Using a mass-balance model, the author calculated P loadings from present-day P concentrations measured in lake water and from other easily measured physical characteristics in a total of 28 lakes in drainage basins that contain only forest and residential land. The loadings from background sources (forest-land drainage and bulk precipitation) to each of the lakes were estimated by methods developed in a previous study. Differences between estimated present-day P loadings and loadings from background sources were attributed to changes in land use. The mean increase in annual P yield resulting from conversion of forest to residential land use was 7 kilograms per square kilometer, not including septic tank system contributions. Calculated loadings from septic systems were found to correlate best with the number of near-shore dwellings around each lake in 1940. The regression equation expressing this relationship explained 36 percent of the sample variance. There was no significant correlation between estimated septic tank system P loadings and number of dwellings present in 1960 or 1970. The evidence indicates that older systems might contribute more phosphorus to lakes than newer systems, and that there may be substantial time lags between septic system installation and significant impacts on lake-water P concentrations. For lakes in basins that contain agricultural land, the P loading attributable to agriculture can be calculated as the difference between the estimated total loading and the sum of estimated loadings from nonagricultural sources. A comprehensive system for evaluating errors in all loading estimates is presented. The empirical relationships developed allow preliminary approximations of the cumulative impact development has had on P loading and the amounts of P loading from generalized land-use categories for Puget Sound lowland lakes. In addition, the sensitivity of a lake to increased loading can be evaluated using the mass-balance model. The data required are presently available for most lakes. Estimates of P loading are useful in developing water-quality goals, setting priorities for lake studies, and designing studies of individual lakes. The suitability of a method for management of individual lakes will often be limited by relatively high levels of uncertainty, especially if the method is used to evaluate relatively small increases in P loading.","language":"ENGLISH","publisher":"U.S. G.P.O.,","doi":"10.3133/wsp2240","usgsCitation":"Gilliom, R.J., 1983, Estimation of nonpoint source loadings of phosphorus for lakes in the Puget Sound region, Washington: U.S. Geological Survey Water Supply Paper 2240, iv, 24 p. :ill., 1 map ;28 cm., https://doi.org/10.3133/wsp2240.","productDescription":"iv, 24 p. :ill., 1 map ;28 cm.","costCenters":[],"links":[{"id":138235,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/wsp/2240/report-thumb.jpg"},{"id":26749,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/wsp/2240/report.pdf","linkFileType":{"id":1,"text":"pdf"}}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a0ae4b07f02db5fb25d","contributors":{"authors":[{"text":"Gilliom, Robert J. rgilliom@usgs.gov","contributorId":488,"corporation":false,"usgs":true,"family":"Gilliom","given":"Robert","email":"rgilliom@usgs.gov","middleInitial":"J.","affiliations":[{"id":451,"text":"National Water Quality Assessment Program","active":true,"usgs":true}],"preferred":true,"id":143954,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}} ,{"id":36549,"text":"fwsobs82_10_32 - 1983 - Habitat Suitability Index Models: Lewis' woodpecker","interactions":[],"lastModifiedDate":"2022-02-15T14:24:02.893398","indexId":"fwsobs82_10_32","displayToPublicDate":"1994-01-01T00:00:00","publicationYear":"1983","noYear":false,"publicationType":{"id":18,"text":"Report"},"publicationSubtype":{"id":1,"text":"Federal Government Series"},"seriesTitle":{"id":20,"text":"FWS/OBS","active":false,"publicationSubtype":{"id":1}},"seriesNumber":"82/10.32","subseriesTitle":"Habitat Suitability Index","title":"Habitat Suitability Index Models: Lewis' woodpecker","docAbstract":"

The Shield is bordered on the southwest by Cenozoic sedimentary and igneous rocks of the Red Sea paar and on the east by the Arabian Platform, an area of basin sedimentation throughout Phanerozoic time. The Shield appears to have been formed by successive episodes of island arc volcanism and sea-floor spreading, followed by several cycles of compressive tectonism and metamorphism. An interpretation and synthesis of a deep-refraction seismic profile from the Riyadh area to the Farasan Islands, and regional gravity, aeromagnetic, heat flow, and surface geologic data have yielded a self-consistent regional-scale model of the crust and upper mantle for this area. \r\n\r\nThe model consists of two 20 km-thick layers of crust with an average compressional wave velocity in the upper crust of about 6.3 km/s and an average velocity in the lower. crust of about 7.0 km/s. This crust thins abruptly to less than 20 km near the southwestern end of the profile where Precambrian outcrops abut the Cenozoic rocks and to 8 km beneath the Farasan Islands. The data over the coastal plain and Red Sea shelf areas are fit satisfactorily by an oceanic crustal model. A major lateral velocity inhomogeneity in the crust is inferred about 25 km northeast of Sabhah and is supported by surface geologic evidence. \r\n\r\nThe major velocity discontinuities occur at about the same depth across the entire Shield and are interpreted to indicate horizontal metamorphic stratification of the Precambrian crust. Several lateral inhomogenities in both the upper and lower .crust of the . Shield are interpreted, to indicate bulk compositional variations. \r\n\r\nThe subcrustal portion of the model is composed of a hot, low-density lithosphere beneath the Red Sea which is systematically cooler and denser to the northeast. This model provides a mechanism which explains the observed topographic uplift, regional gravity pattern, heat flow, and mantle compressional wave velocities. Such a lithosphere could be produced by upwelling of hot asthenosphere beneath the Red Sea which then flows laterally beneath the lithosphere of the Arabian Plate.","language":"ENGLISH","publisher":"U.S. Geological Survey,","doi":"10.3133/ofr83638","usgsCitation":"Gettings, M.E., Blank, H., Mooney, W.D., and Healy, J.H., 1983, Crustal structure of southwestern Saudi Arabia: U.S. Geological Survey Open-File Report 83-638, ii, 55 p. ill., maps ;28 cm., https://doi.org/10.3133/ofr83638.","productDescription":"ii, 55 p. ill., maps ;28 cm.","costCenters":[],"links":[{"id":140175,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/of/1983/0638/report-thumb.jpg"},{"id":34400,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/1983/0638/report.pdf","linkFileType":{"id":1,"text":"pdf"}}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4acee4b07f02db67f432","contributors":{"authors":[{"text":"Gettings, M.

A study was made, in cooperation with the Division of Water Resources, Kansas State Board of Agriculture, to determine geohydrologic conditions in an area comprising nearly 850,000 acres along the Arkansas River valley in Kearny and Finney Counties, southwestern Kansas. The Arkansas River meanders atop and interacts hydraulically with the area's multilayered, unconsolidated aquifer system. Declines in static water levels in wells in
the heavily pumped lower aquifer ranged from 20 to 80 feet during 1974-80. The river is dry in much of the area.

A digital computer model was calibrated to simulate the trends of historic water levels. Simulated 1974-80 conditions depicted an average annual recharge to the unconsolidated aquifer system of 66,900 acre-feet from precipitation and 36,200 acre-feet from river and canal seepage and boundary inflow. Simulated average annual discharge consisted of 634,800 acre-feet from pumpage and boundary outflow. Simulated average annual recharge to the unconsolidated aquifer system was 531,700 acre-feet less than average annual discharge, indicating the ground-water resource is currently (1982) being mined in the study area.

Simulation also indicated that there would be sufficient saturated thickness in 2005 for irrigation if 1980 hydrologic conditions continued. Seepage losses from the Arkansas River and irrigation canals are a major source of recharge to the unconsolidated aquifer system. Therefore, the amount of flow in the Arkansas River would be important in determining the rate of future water-level declines in the study area. Streamflow seepage losses could be decreased by (1) decreasing the number of wells pumping in the study area in order to reduce downward leakage from the valley aquifer, or (2) increasing streamflow discharge in order to recharge the valley aquifer. The rate and direction of flow between the river and the valley aquifer depend on the hydraulic conductivity of the streambed and the hydraulic gradient between the river stage and the water table. As long as river stage remains high, the water table in the valley aquifer continues to rise. Seepage from the river to the valley aquifer decreases as the altitude difference between the river stage and the valley aquifer decreases, becoming insignificant when the water level in the valley aquifer nearly equals river stage. However, a rise in the water table in the valley aquifer because of recharge from the river will correspond to increased downward leakage to the lower aquifer, impeding recharge to the valley aquifer.

These induced compressive stresses are predicted by computer calculations, but have never been adequately confirmed by field measurements, owing primarily to the unique difficulties of obtaining such field data. Vibrating-wire stressmeter measurements made near the Mighty Epic nuclear detonation, however, qualitatively indicate that within 150 meters of the working point, permanent compressive stress increases of several megapascals were present 15 weeks after the event. Additionally, stress-change magnitudes interpreted from the stressmeter data between the 75- and 260-meter range from the working point compare favorably with calculational predictions of the stress changes believed to be present shortly after detonation of the event. The measurements and calculations differ, however, with regard to the pattern of stress change radial and transverse to the explosion source. For the range of the field measurements from the working point, computer models predict the largest compressive-stress increase to be radial to the explosion source, while the field data indicate the transverse component of. stress change to be the most compressive. The significance of time-dependent modification of the initial explosion-induced stress distribution is, however, uncertain with regard to the comparison of the field measurements and theoretical predictions.","language":"ENGLISH","publisher":"U.S. Geological Survey,","doi":"10.3133/ofr83642","usgsCitation":"Ellis, W., and Kibler, J., 1983, Explosion-induced stress changes estimated from vibrating-wire stressmeter measurements near the Mighty Epic event, Nevada Test Site: U.S. Geological Survey Open-File Report 83-642, i, 28 p. ill., maps ;28 cm., https://doi.org/10.3133/ofr83642.","productDescription":"i, 28 p. ill., maps ;28 cm.","costCenters":[],"links":[{"id":142035,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/of/1983/0642/report-thumb.jpg"},{"id":36313,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/1983/0642/report.pdf","linkFileType":{"id":1,"text":"pdf"}}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a0ee4b07f02db5fdea6","contributors":{"authors":[{"text":"Ellis, William L.","contributorId":89128,"corporation":false,"usgs":true,"family":"Ellis","given":"William L.","affiliations":[],"preferred":false,"id":158231,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Kibler, J.D.","contributorId":68311,"corporation":false,"usgs":true,"family":"Kibler","given":"J.D.","email":"","affiliations":[],"preferred":false,"id":158230,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}} ,{"id":9438,"text":"ofr82901 - 1983 - Microcumpter computation of water quality discharges","interactions":[],"lastModifiedDate":"2012-02-02T00:06:23","indexId":"ofr82901","displayToPublicDate":"1994-01-01T00:00:00","publicationYear":"1983","noYear":false,"publicationType":{"id":18,"text":"Report"},"publicationSubtype":{"id":5,"text":"USGS Numbered Series"},"seriesTitle":{"id":330,"text":"Open-File Report","code":"OFR","onlineIssn":"2331-1258","printIssn":"0196-1497","active":true,"publicationSubtype":{"id":5}},"seriesNumber":"82-901","title":"Microcumpter computation of water quality discharges","docAbstract":"A fully prompted program (SEDQ) has been developed to calculate daily and instantaneous water quality (QW) discharges.

H. Darton at the turn of the century. Since then, hydrogeologists have debated the source of the large quantities of water which have been discharged by artesian flow from the Dakota. Among suggestions for the source of this water are (1) recharge of the aquifer at outcrops in the Black Hills, (2) compaction and compressive storage within the aquifer, (3)leakage through confining layers, and (4) upward flow from the underlying Madison Group limestones. \r\n\r\nA series of increasingly refined models of the aquifer system in South Dakota have been developed and used for numerical simulations of the ground-water flow. The simulations have provided estimates of leakage through the confining layers. The results indicate that, before development, most of the flow into and out of the Dakota Sandstone occurred as leakage through confining layers and, since development, most of the water released from storage has come from the confining layers. \r\n\r\nIn situ and laboratory hydraulic conductivity measurements have been made for the Cretaceous shale confining layer which overlies the Dakota. These data indicate hydraulic conductivities which are one to three orders of magnitude lower than the conductivities indicated by the numerical analyses; this suggests that the leakage through the confining layer is largely through fractures. The fractures apparently did not influence the laboratory and in situ measurements. \r\n\r\nTo test the conception of flow in the aquifer-confining layer system derived from our analyses, the transport of sulfate in the system was simulated. Simulations using a numerical ground-water transport model were reasonably successful in explaining the present distribution of sulfate in the system. This result increases confidence in the flow system implied by the flow simulations in which leakage through confining layers is dominant.","language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/wsp2237","usgsCitation":"Bredehoeft, J.D., Neuzil, C., and Milly, P.C., 1983, Regional flow in the Dakota aquifer: A study of the role of confining layers: U.S. Geological Survey Water Supply Paper 2237, iv, 45 p., https://doi.org/10.3133/wsp2237.","productDescription":"iv, 45 p.","costCenters":[],"links":[{"id":411005,"rank":3,"type":{"id":36,"text":"NGMDB Index Page"},"url":"https://ngmdb.usgs.gov/Prodesc/proddesc_25541.htm","linkFileType":{"id":5,"text":"html"}},{"id":25731,"rank":2,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/wsp/2237/report.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":138082,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/wsp/2237/report-thumb.jpg"}],"country":"United States","state":"Nebraska, South Dakota","otherGeospatial":"Dakota aquifer","geographicExtents":"{\n \"type\": \"FeatureCollection\",\n \"features\": [\n {\n \"type\": \"Feature\",\n \"properties\": {},\n \"geometry\": {\n \"coordinates\": [\n [\n [\n -96.432,\n 45.946\n ],\n [\n -104.049,\n 45.946\n ],\n [\n -104.049,\n 42.477\n ],\n [\n -96.432,\n 42.477\n ],\n [\n -96.432,\n 45.946\n ]\n ]\n ],\n \"type\": \"Polygon\"\n }\n }\n ]\n}","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a27e4b07f02db610782","contributors":{"authors":[{"text":"Bredehoeft, John D.","contributorId":86747,"corporation":false,"usgs":true,"family":"Bredehoeft","given":"John","email":"","middleInitial":"D.","affiliations":[],"preferred":false,"id":143104,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Neuzil, C.

Geologic, geochemical, and geophysical studies within the Raywood \"Flat Roadless Areas, together with an investigation of mines and prospects within the further planning area, resulted in (1) identification of nonmetallic mineral resources at a marble mine in the further planning area and (2) recognition of a small area in the recommended wilderness that has moderate potential for base-metal resources. Except for these two areas of identified and suspected resources, we did not observe indications of resource potential elsewhere in the Raywood Flat Roadless Areas.

\n

The area having nonmetallic mineral resources is in the vicinity of the Mill Creek mine near the northeastern boundary of the further planning area (B5-187); there, we identified marginal reserves of marble suitable for the production of lime and construction stone. The reserves are marginal because of their remote location and poor accessibility. Geologic mapping did not reveal any additional marble occurrences within the study area.

\n

The area having moderate potential for base-metal resources forms a small zone in the eastern part of the recommended wilderness (A5-187). Within this zone, evidence provided by stream-sediment geochemistry suggests that crystalline bedrocks in several drainages contain concentrations of metallic elements. Because the terrain is inaccessible and covered with dense brush, most of the bedrock in the specific drainages containing the geochemical anomalies could not be examined. Thus, although we infer that mineral occurrences exist in the drainage basins, we have little data on which to base an estimate of their extent and quality. Locally, the crystalline rocks probably contain hydrothermal veins or disseminated occurrences where lead, copper, molybdenum, tin, cobalt, bismuth, and arsenic have been concentrated. However, the geochemical anomalies for these metals are small, and the stream drainages also are relatively small. Therefore, the inferred occurrences of metallic minerals probably are small scale, scattered, and low grade. There is only low probability that the inferred mineral occurrences are large scale.

About 500 lode gold occurrences, prospects, and mines have been reported from the Medford 1o x 2o quadrangle, Oregon-California. Summary descriptions of individual lode gold deposits and districts which include those occurrences in the Medford 1o x 2o quadrangle have been published by Brooks and Ramp (1968) and Hotz (1971) and by others cited in the reference lists in these two publications. As part of the Medford CUSMAP project between 1974 and 1980, some of these deposits were examined in the field during geologic mapping and geochemical sampling and most of the available information on individual deposits was compiled into a CRIB computer file (Computerized Resource Information Bank). This report is a summary of the more pertinent geologic and economic characteristics of the lode gold deposits for use in the resource evaluation part of the Medford CUSMAP project. The significant features described include the distribution of deposits and their relation to gross geologic and lithologic features, production information, mineralogy of the ore and gangue, gold-silver ratios, and speculations on possible genetic models for some types of deposits.

The N aquifer consists of the Navajo Sandstone and parts of the underlying Kayenta Formation and Wingate Sandstone of Jurassic and Triassic age. Maximum saturated thickness of the aquifer is about 1,050 feet in the northwestern part of the area, and the aquifer thins to extinction to the southeast. Water is under confined conditions in the central 3,300 square miles of the area. To the east, north, and west of Black Mesa, the aquifer is exposed at the surface, and water is unconfined. The aquifer was in equilibrium before about 1965. Recharge of about 13,000 acre-feet per year was balanced primarily by discharge near Moenkopi Wash and Laguna Creek and by evapotranspiration. At least 180 million acre-feet of water was in storage. The estimated average hydraulic conductivity of the aquifer is 0.65 foot per day. The confined storage coefficient is estimated to be about 0.0004 where the aquifer is thickest, and the estimated unconfined storage coefficient ranges from 0.10 to 0.15. \r\n\r\nGround-water withdrawals that averaged 5,300 acre-feet per year from 1976 to 1979 have caused water levels to decline in wells in the confined part of the aquifer. Withdrawals include an average of 3,700 acre-feet per year to supply a coal-slurry pipeline from a coal mine on Black Mesa. Six observation wells equipped with water-level recorders have been used to monitor aquifer response. The water level in one well 32 miles south of the mine declined 17 feet from 1972 through 1979 and 3.5 feet during 1979. \r\n\r\nA mathematical model of the N aquifer was developed and calibrated for equilibrium and nonequilibrium conditions. The model was used in part to improve estimates of aquifer characteristics and the water budget, and it successfully reproduced the observed response of the aquifer through 1979. The model results indicate that about 95 percent of the 44,000 acre-feet of water pumped from 1965 to 1979 was withdrawn from storage, but the reduction amounted to less than 0.03 percent of total storage. Water-level declines through 1979 were estimated to be more than 100 feet in an area of 200 square miles. Four projections of future water-level changes were made using the model. The most probable projection indicates that water-level declines would exceed 100 feet in an area of 440 square miles by 2001.

High aeroradioactivity is associated with potassium-rich granitic plutons, muscovite-rich gneisses, schists, and metavolcanic rocks; positive gravity and magnetic anomalies are associated with gabbro plutons; and negative gravity anomalies are associated with granitic plutons. \r\n\r\nAt the west side of the slate belt, the Tillery phyllite is interpreted as having undergone progressive metamorphism. The underlying Uwharrie Formation extends into the Charlotte belt where it is mapped as metavolcanic rocks. Gravity models of the Carolina slate belt indicate that it is a synform containing a wedge of metasedimentary and volcanoclastic rock on plutonic basement. The basement is exposed in the adjacent Charlotte belt antiform. \r\n\r\nThe northern Charlotte belt contains mainly plutonic rocks which have been divided into 3 supergroups of plutons based upon chemistry, mineralogy, texture, and age. They are: \r\n\r\n1. Old Plutonic supergroup - plutons 545-490 m.y. that are medium to coarse-grained tonalite, quartz diorite, and granodiorites. \r\n\r\n2. Concord-Salisbury supergroup -- plutons 426-350 m.y. which form sheet-like intrusions of differentiated gabbro; local volcanic centers with ring complexes 13 km in diameter that suggest magma chambers 0 - 8 km deep; smaller bodies of diorite, monzonite, and syenite; and small Salisbury type granodiorites. \r\n\r\n3. Landis supergroup -- plutons 350-280 m.y. that are usually very coarse-grained, porphyritic, 'big feldspar,' potassium-rich granites. \r\n\r\nThe Mecklenburg-Weddington gabbro complex of the Concord-Salisbury supergroup, the largest feature in the study area, contains three large gabbro plutons. The gabbro intruded old Plutonic complex rocks and could-have produced the metamorphic reaction K-feldspar + sillimanite quartz + muscovite reflected in the mineral assemblage of adjacent felsic metavolcanic rocks. Gravity models indicate a lopolith 3.5- to 4.5-km thick with a 2 km sill extending to the northeast. Positive magnetic and gravity anomalies suggest the lopolith is. connected with the Concord gabbro complex to the northeast. \r\n\r\nThe sheet-like intrusions of Concord-Salisbury group gabbros, forming the core of the composite 5atholith, have medium-grained Salisbury type granodiorite above, and coarser-grained Landis granite below. The position of the supergroups as presently exposed may be a function of level of erosion versus level of emplacement. The plutons in the composite batholith span 200 m.y. according to current age data and are arranged with the oldest at the top and the youngest at the bottom. However, Rb-Sr and K-At ages in the Piedmont are more likely to reflect age of crustal uplift than the age of metamorphism or intrusion. The Charlotte belt composite batholith, therefore, may very well be the result of a shorter single tectonic event or process.","language":"ENGLISH","publisher":"U.S. Geological Survey,","doi":"10.3133/ofr8393","usgsCitation":"Wilson, F., 1983, Geophysical and geologic studies in southern Mecklenburg County and vicinity, North Carolina and South Carolina: U.S. Geological Survey Open-File Report 83-93, 199 p. ill., maps ;28 cm., https://doi.org/10.3133/ofr8393.","productDescription":"199 p. ill., maps ;28 cm.","costCenters":[{"id":13634,"text":"South Atlantic Water Science Center","active":true,"usgs":true}],"links":[{"id":39562,"rank":401,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/of/1983/0093/plate-2.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":39561,"rank":400,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/of/1983/0093/plate-1.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":39563,"rank":402,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/of/1983/0093/plate-3.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":39564,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/1983/0093/report.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":144993,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/of/1983/0093/report-thumb.jpg"}],"country":"United States","state":"North Carolina, South Carolina","county":"Mecklenburg County","geographicExtents":"{\n \"type\": \"FeatureCollection\",\n \"features\": [\n {\n \"type\": \"Feature\",\n \"properties\": {},\n \"geometry\": {\n \"type\": \"Polygon\",\n \"coordinates\": [\n [\n [\n -81.19308471679688,\n 34.84762101276787\n ],\n [\n -81.19308471679688,\n 35.74316846139925\n ],\n [\n -80.4144287109375,\n 35.74316846139925\n ],\n [\n -80.4144287109375,\n 34.84762101276787\n ],\n [\n -81.19308471679688,\n 34.84762101276787\n ]\n ]\n ]\n }\n }\n ]\n}","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4ac8e4b07f02db67c208","contributors":{"authors":[{"text":"Wilson, Frederick A.","contributorId":100352,"corporation":false,"usgs":true,"family":"Wilson","given":"Frederick A.","affiliations":[],"preferred":false,"id":163574,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}} ,{"id":29288,"text":"wri834022 - 1983 - Simulations of non-steady flow in a glacial outwash aquifer, southern Franklin County, Ohio","interactions":[],"lastModifiedDate":"2012-02-02T00:08:45","indexId":"wri834022","displayToPublicDate":"1994-01-01T00:00:00","publicationYear":"1983","noYear":false,"publicationType":{"id":18,"text":"Report"},"publicationSubtype":{"id":5,"text":"USGS Numbered Series"},"seriesTitle":{"id":342,"text":"Water-Resources Investigations Report","code":"WRI","active":false,"publicationSubtype":{"id":5}},"seriesNumber":"83-4022","title":"Simulations of non-steady flow in a glacial outwash aquifer, southern Franklin County, Ohio","docAbstract":"A two-dimensional, finite-difference model is used to simulate transient flow conditions in a glacial outwash aquifer in southern Franklin County, Ohio.

Since 1973, the U.S. Geological Survey (USGS), with support from the Nuclear Regulatory Commission, has conducted extensive investigations of the tectonic and seismic history of the Charleston, S.C., earthquake zone and surrounding areas. The goal of these investigations has been to discover the cause of the large intraplate Charleston earthquake of 1886, which dominates the record of seismicity in the Southeastern United States, through an understanding of the historic and modern seismicity at Charleston and of the tectonic setting of the seismicity. This goal is being pursued to evaluate the potential for additional large earthquakes in the Charleston area and surrounding regions and to determine whether the Charleston area differs tectonically in any significant fashion from other parts of the Southeastern United States. An understanding of the specific cause for the 1886 event and of the regional distribution of any structures that are generically related to or geometrically and mechanically similar to the source structure is essential for evaluation of seismic hazards throughout the Southeast.

The results given herein represent significant progress toward understanding the tectonic setting of the Charleston-area seismicity. Several chapters in the volume address the distribution and origin of pre-Cretaceous rocks and structures beneath Coastal Plain sediments in the Charleston area and regionally beneath the southern Atlantic Coastal Plain and adjacent Continental Shelf. The modern seismicity at Charleston is occurring at depths equal to or greater than the known extent of these older structures, and rejuvenation of an older fault in the modern stress field is a possible cause of the seismicity. Accordingly, several chapters discuss the possible relationships of the various pre-Cretaceous structures to faults identified near Charleston that have a known Cretaceous and Cenozoic movement history and to the historic and instrumentally recorded seismicity. However, at the present time, none of the young structures can be related unequivocally to the seismicity because earthquake fault-plane solutions and hypocenter distributions do not agree with the locations and orientations of these structures. Therefore, a major emphasis of continuing USGS investigations near Charleston will be to identify additional faults, if any exist, to delineate fault movement histories, and to further refine earthquake locations, focal mechanisms, and related seismological interpretations.

In a few places the anomalies are caused by intrusions. Correlation between magnetic properties measured from rock samples and those derived from rock unit-magnetic anomaly associations is excellent. Anomaly characteristics, extensive magnetic gradients, and marked changes in the regional magnetic field can be coupled with the magnetic properties of the rock units to delineate structural boundaries. Three major boundaries are indicated by contrasts in regional magnetic expressions. Less extensive but more clearly indicated boundaries in the immediate vicinity of Yucca Mountain are interpreted from a distinctive pairing of northerly-trending linear positive and negative anomalies which are caused by vertical displacement in generally gently dipping volcanic beds. The displacement between beds is located approximately along the border line between the linear anomaly pairs. One series of pairs of more northeasterly trend lies over the general location of a change from moderately thick to very thick volcanic units that was interpreted from gravity data. Several low amplitude but distinctively shaped anomalies in areas underlain primarily by sedimentary strata indicate the presence of intrusions and faults.","language":"ENGLISH","publisher":"U.S. Geological Survey,","doi":"10.3133/ofr83616","usgsCitation":"Kane, M.F., and Bracken, R.E., 1983, Aeromagnetic map of Yucca Mountain and surrounding regions, southwest Nevada: U.S. Geological Survey Open-File Report 83-616, i, 19 p. :maps ;28 cm.; 1 over-size sheet; scale 1:48000 (1 inch = 4000 feet), https://doi.org/10.3133/ofr83616.","productDescription":"i, 19 p. :maps ;28 cm.; 1 over-size sheet; scale 1:48000 (1 inch = 4000 feet)","costCenters":[],"links":[{"id":110628,"rank":700,"type":{"id":15,"text":"Index Page"},"url":"https://ngmdb.usgs.gov/Prodesc/proddesc_75697.htm","linkFileType":{"id":5,"text":"html"},"description":"75697"},{"id":143105,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/of/1983/0616/report-thumb.jpg"},{"id":37479,"rank":400,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/of/1983/0616/plate-1.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":37480,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/1983/0616/report.pdf","linkFileType":{"id":1,"text":"pdf"}}],"scale":"48000","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4aeee4b07f02db6911ca","contributors":{"authors":[{"text":"Kane, Martin Francis","contributorId":87923,"corporation":false,"usgs":true,"family":"Kane","given":"Martin","email":"","middleInitial":"Francis","affiliations":[],"preferred":false,"id":160213,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Bracken, Robert E. 0000-0001-7759-2743 rbracken@usgs.gov","orcid":"https://orcid.org/0000-0001-7759-2743","contributorId":2640,"corporation":false,"usgs":true,"family":"Bracken","given":"Robert","email":"rbracken@usgs.gov","middleInitial":"E.","affiliations":[{"id":35995,"text":"Geology, Geophysics, and Geochemistry Science Center","active":true,"usgs":true}],"preferred":true,"id":160212,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}} ,{"id":7782,"text":"ofr83677 - 1983 - Hydrology of the Jasper (Miocene) Aquifer in the Southeast Texas coastal plain","interactions":[],"lastModifiedDate":"2025-09-23T16:51:31.349837","indexId":"ofr83677","displayToPublicDate":"1994-01-01T00:00:00","publicationYear":"1983","noYear":false,"publicationType":{"id":18,"text":"Report"},"publicationSubtype":{"id":5,"text":"USGS Numbered Series"},"seriesTitle":{"id":330,"text":"Open-File Report","code":"OFR","onlineIssn":"2331-1258","printIssn":"0196-1497","active":true,"publicationSubtype":{"id":5}},"seriesNumber":"83-677","title":"Hydrology of the Jasper (Miocene) Aquifer in the Southeast Texas coastal plain","docAbstract":"

The Jasper (Miocene) aquifer is one of several important hydrologic units in the Gulf Coastal Plain. Because the Jasper aquifer underlies shallower aquifers in many areas, regional water withdrawals from the Jasper are not significant; however, it is capable of yielding 3,000 gallons per minute (200 liters per second) or more of water to wells in certain areas. The Jasper is underlain by the Catahoula confining system (restricted) and overlain by the Burkeville confining system. The Evangeline and Chicot aquifers, in turn, overlie the Burkeville and also are prolific water-yielding aquifers.

The ground-water hydrology of the Jasper aquifer in an area of about 20,000 square miles (52,000 square kilometers) was simulated by a two-dimensional digital model using a steady-state approach. The model represents hydrologic conditions prior to development by wells, when natural recharge equaled natural discharge. The model's grid pattern of 15 x 24 nodes varies from a dimension of 5 by 10 miles (8 by 16 kilometers) in the outcrop to 10 by 10 miles (16 by 16 kilometers) in the artesian section downdip from the outcrop.

This survey (888 km), of the New Jersey nearshore area, extended between Corson Inlet to the south and Mlanasquan Inlet to the north and from about 8 m depth to about 25 m depth. The lines were located between latitudes 39° and 40°10'N and longitudes 73°50' and 74° 40'W. High-resolution seismic­reflection data were collected using an EG&G Uniboom (400-4000 Hz) and an ORE Mode! 1035 (3.5 kHz) subbottom profiling system in conjunction with a Klein Sidescan Sonar System (100 kHz). While the quality of the data is variable, it is virtually all usable and generally of good quality but rarely excellent. Due to equipment failure, only 880 km of 3.5 kHz and 796 km of sidescan-sonar data were recorded. Navigation was by Loran-C. and fixes were recorded at 5-minute time intervals with some gaps in the data.

Analysis of the sidescan-sonar data shows five recognizable features in the study area. Megaripples (2-3 m crestal spacing) were recorded almost exclusively on coast parallel tracklines, and were most abundant at distances of 10 to 20 km offshore. Nonlinear light and dark patches were abundant in the northern half of the study area and offshore to the south. Two groups of linear light and dark bands were observed as being clearly parallel or oblique to the bathymetric contours and were noted throughout the survey area. Trawl marks were noted on only one line near the shore, just north of Barnegat Inlet.

These observations indicate widespread, perhaps frequent, movement of the surface sands on the Inner New Jersey continental shelf. Directions of sediment transport are suggested by the orientation of the alternating light and dark bands and the ripples, assuming a parallel and/or transverse relative movement. Asymmetry of the ripples was not observed on the sidescan sonographs.

The high-resolution seismic-reflection profiles indicate three distinct types of subbottom stratigraphy in the top 20 to 40 m of sediment. Reflectors in the area north of Barnegat Inlet dip gently (<1° ) to the south-southeast. The thirty plotted reflectors are 5 to 12 m apart (vertically), are essentially parallel, and are truncated on the updip (northern) limits where they outcrop or subcrop (under a 2-4 m overburden). Truncated by erosion, they are the dominant cause of N65° east-striking topographic ridges in this offshore region. The age of the reflectors is· inferred to be Tertiary from the strike and dip, which are the same as the Tertiary beds of adjacent New Jersey.
