Unavoidable uncertainty in the true stress on the prototype and in the true response of the prototype to that stress will introduce errors into the parameter identification problem. A method for evaluating errors in the predictions of future water levels due to errors in recharge estimates was demonstrated. The method involves a Monte Carlo simulation of the parameter identification problem and of the prediction problem. The steps in the method are: (1) to prescribe the distribution of the recharge estimates; (2) to use this distribution to generate random sets of recharge estimates; (3) to use the Gauss optimization technique to identify the corresponding set of parameter estimates for each set of recharge estimates; (4) to make the corresponding set of hydraulic head predictions for each set of parameter estimates; and (5) to examine the distribution of hydraulic head predictions and to draw appropriate conclusions. Similarly, the method can be used independently or simultaneously to estimate the effect on hydraulic head predictions of errors in the measured water levels that are used in the parameter identification problem. The fit of the model to the data that are used to identify parameters is not a good indicator of these errors. A Monte Carlo simulation of the parameter identification problem can be used, however, to evaluate the effects on water level predictions of errors in the recharge (and pumpage) data used in the parameter identification problem.

Dispersion is pronounced in all the resistivity data above 106 Hz. As water content decreases, resistivity dispersion becomes noticeable at lower frequencies. The resistivity data at all frequencies, however, fit an empirical prediction formula relating observed resistivity to water saturation and resistivity of the saturated sample. The data suggest that the dispersion of resistivity of some earth materials with frequency may be predicted on the basis of curve matching of the data obtained in this investigation with the resistivity of the material at a frequency of 100 Hz or lower. \r\n\r\nThe dispersion of dielectric constant with frequency is pronounced at all frequencies, being more pronounced with increasing water content.

It has been prepared to aid and encourage the field-oriented coal scientist to participate directly in petrographic coal-description activities. The objectives and past and current practices of coal description vary widely. These are briefly reviewed and illustrated with examples. Sampling approaches and techniques for collecting columnar samples of fresh coal are also discussed. The recommended procedures and methodology emphasize the fact that obtaining a good megascopic description of a coal bed is much better done in the laboratory with a binocular microscope and under good lighting conditions after the samples have been cut and quickly prepared. For better observation and cross-checking using a petrographic microscope for identification purposes, an in-place polishing procedure (requiring less than 2 min) is routinely used. Methods for using both the petrographic microscope and an automated image analysis system are also included for geologists who have access to such instruments. To describe the material characteristics of a coal bed in terms of microlithotypes or lithotypes, a new nomenclature of (V), (E), (1), (M). (S). (X<sub>1</sub>). (X<sub>2</sub>) and so on is used. The microscopic description of the modal composition of a megascopically observed lithologic type is expressed in terms of (VEIM); subscripts are used to denote the volume percentage of each constituent present. To describe a coal-bed profile, semiquantitative data (without microscopic study) and quantitative data (with microscopic study) are presented in ready-to-understand form. The average total composition of any thickness interval or of the entire coal bed can be plotted on a triangular diagram having V, E, and I+ M +S as the apices. The modal composition of any mixed lithologies such as (X<sub>1</sub>), (X<sub>2</sub>), and so on can also be plotted on such a triangular ternary diagram. Such diagrams can be used either for tracing compositional variations throughout a single coal-bed profile or for comparing variations between different coal beds.","language":"ENGLISH","publisher":"U.S. Geological Survey,","doi":"10.3133/cir894","usgsCitation":"Chao, E., Minkin, J., and Thompson, C., 1983, Recommended procedures and methodology of coal description: U.S. Geological Survey Circular 894, iv, 31 p., https://doi.org/10.3133/cir894.","productDescription":"iv, 31 p.","numberOfPages":"36","costCenters":[],"links":[{"id":139148,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/circ/0894/report-thumb.jpg"},{"id":271070,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/circ/0894/report.pdf"}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a74e4b07f02db644603","contributors":{"authors":[{"text":"Chao, E.C.","contributorId":47358,"corporation":false,"usgs":true,"family":"Chao","given":"E.C.","email":"","affiliations":[],"preferred":false,"id":148153,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Minkin, J.A.","contributorId":38588,"corporation":false,"usgs":true,"family":"Minkin","given":"J.A.","affiliations":[],"preferred":false,"id":148152,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Thompson, C.L.","contributorId":12189,"corporation":false,"usgs":true,"family":"Thompson","given":"C.L.","email":"","affiliations":[],"preferred":false,"id":148151,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

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}]}}

Construction of the Trans-Alaskan Pipeline System has now made the quadrangle accessible by road. In 1975 and 1976 a team of geologists, geochemists, and geophysicists investigated the quadrangle in order to assess its mineral resource potential. This report is a guide to the resulting folio of twelve maps that \r\ndescribe the geology, stream sediment geochemistry, aeromagnetic features, Landsat imagery, and mineral resources of the area. \r\n\r\nThe bedrock geology and aeromagnetic surveys show that mineral deposits associated with intrusive rocks are probably absent. However, the geology and geochemical anomalies do indicate the possibility of vein and strata-bound deposits of copper, lead, and zinc in the Paleozoic shale and carbonate rocks in the southern part of the quadrangle and of stratabound deposits of zinc and copper in the Permian and Mesozoic shales along the mountain front. The northwestern part of the quadrangle has a low to moderate potential for oil or gas; Mississippian carbonate rocks are the most likely reservoir. The only minerals produced to date have been construction materials.","language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/cir759","usgsCitation":"Reiser, H.N., Brosge, W., Hamilton, T.D., Singer, D., Menzie, W., Bird, K.J., Cady, J.W., Le Compte, J., and Cathrall, J.B., 1983, The Alaska Mineral Resource Assessment Program: Guide to information contained in folio of geologic and mineral resource maps of the Philip Smith Mountains quadrangle, Alaska: U.S. Geological Survey Circular 759, iii, 22 p., https://doi.org/10.3133/cir759.","productDescription":"iii, 22 p.","costCenters":[],"links":[{"id":407826,"rank":3,"type":{"id":36,"text":"NGMDB Index Page"},"url":"https://ngmdb.usgs.gov/Prodesc/proddesc_23988.htm","linkFileType":{"id":5,"text":"html"}},{"id":31340,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/circ/1983/0759/report.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":139312,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/circ/1983/0759/report-thumb.jpg"}],"country":"United States","state":"Alaska","otherGeospatial":"Philip Smith Mountains quadrangle","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -150,\n              68\n            ],\n            [\n              -147,\n              68\n            ],\n            [\n              -147,\n              69\n            ],\n            [\n              -150,\n              69\n            ],\n            [\n              -150,\n              68\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4ad5e4b07f02db683538","contributors":{"authors":[{"text":"Reiser, H.

The impacts of subsidence are potentially severe in terms of damage to surface utility lines and structures, changes in surface-water and ground-water conditions, and effects on vegetation and animals. Although subsidence cannot be eliminated, it can be reduced or controlled in areas where deformation of the ground surface would produce dangerous or costly effects. \r\n\r\nSubsidence prediction is highly developed in Europe where there are comparatively uniform mining conditions and a long history of field measurements. Much of this mining has been carried out beneath crowded urban and industrial areas where accurate predictions have facilitated use of the surface and reduced undesirable impacts. Concerted efforts to understand subsidence processes in the United States are recent. Empirical methods of subsidence analysis and prediction based on local conditions seem better suited to the current state of knowledge of the varied geologic and topographic conditions in domestic coal mining regions than do theoretical/mathematical approaches. In order to develop broadly applicable subsidence prediction methods and models for the United States, more information is needed on magnitude and timing of ground movements and geologic properties.","language":"ENGLISH","publisher":"U.S. Geological Survey,","doi":"10.3133/cir876","usgsCitation":"Lee, F.T., and Abel, J., 1983, Subsidence from underground mining; environmental analysis and planning considerations: U.S. Geological Survey Circular 876, iv, 28 p. :ill., maps ;26 cm., https://doi.org/10.3133/cir876.","productDescription":"iv, 28 p. :ill., maps ;26 cm.","costCenters":[],"links":[{"id":124669,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/circ/1983/0876/report-thumb.jpg"},{"id":30794,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/circ/1983/0876/report.pdf","linkFileType":{"id":1,"text":"pdf"}}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4b05e4b07f02db699ae9","contributors":{"authors":[{"text":"Lee, Fitzhugh T.","contributorId":82272,"corporation":false,"usgs":true,"family":"Lee","given":"Fitzhugh","email":"","middleInitial":"T.","affiliations":[],"preferred":false,"id":147500,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Abel, John F.","contributorId":84351,"corporation":false,"usgs":true,"family":"Abel","given":"John F.","affiliations":[],"preferred":false,"id":147501,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

The study covered a 25-hour period beginning 0900 hours 22 October, 1974. Precipitation during the study period averaged 70 millimeters. Sampling stations were located at Boca de Cangrejos, the main ocean outlet; Canal Pinones between Laguna de Pinones and Laguna La Torrecilla; Canal Suarez between Laguna San Jose, connects to Laguna La Torrecilla; and Cano de Martin Pena between Laguna San Jose and Bahia de San Juan. In addition water-elevation recording gages were installed at each lagoon. \r\n\r\nWater samples from the canal stations were analyzed for organic carbon, nitrogen and phosphorus species, and suspended sediment. Specific-conductance measurements were used with the chemical data to estimate the runoff contributions of nutrients. \r\n\r\nRunoff into the lagoon, system during the study period was about 2.8 million cubic meters, or about 70 percent of the average precipitation. The runoff contributed chemical loadings to the lagoons of 95,000 kilograms total-organic carbon; 2,700 kilograms of total phosphorus; and 10,000 kilograms of total Khjeldhal nitrogen. A comparison with a prior study during which there was no significant rain, show that dry-period loadings are less than 10 percent of the wet-period loadings. At the end of the study period the system had not reached equilibrium, and the lagoons retained 80 percent of the water inflows from 50 to 90 percent of the chemical loads. Nearly 95 percent of the water outflows occurred at the Boca de Cangrejos sea outlet. The three lagoons and interconnecting canals form a very complex hydraulic system that is difficult to study using traditional techniques. A model of the system will facilitate management to improve the quality of water in the lagoons.","language":"ENGLISH","publisher":"U.S. Geological Survey,","doi":"10.3133/ofr82349","usgsCitation":"Gómez-Gómez, F., and Ellis, S.R., 1983, Hydrologic characteristics of lagoons at San Juan, Puerto Rico, during an October 1974 tidal cycle: U.S. Geological Survey Open-File Report 82-349, v, 56 p. :ill., maps ;28 cm., https://doi.org/10.3133/ofr82349.","productDescription":"v, 56 p. :ill., maps ;28 cm.","costCenters":[],"links":[{"id":140931,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/of/1982/0349/report-thumb.jpg"},{"id":36808,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/1982/0349/report.pdf","linkFileType":{"id":1,"text":"pdf"}}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a28e4b07f02db611568","contributors":{"authors":[{"text":"Gómez-Gómez, Fernando","contributorId":31366,"corporation":false,"usgs":true,"family":"Gómez-Gómez","given":"Fernando","affiliations":[],"preferred":false,"id":159268,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Ellis, S.

To test the effects of additional irrigation development on water levels and streamflow , computer programs were developed that represent the surface-water system, soil zone, and saturated zone. A two-dimensional, finite-difference ground-water flow model of the 3,374 square-mile study area was developed and calibrated using steady-state and transient conditions. Three management alternatives were examined. First, 125,000 acre-feet of water would be diverted annually from the Platte River. During a water year in which flows are similar to those in 1957, months of zero streamflow at Grand Island increased from the historical 2, to 7. After 5 years of such low flows, in 36 nodes (997.4 acres per node) water levels declined more than 5 feet, with a maximum decline of 10.7 feet. A second alternative would allow no new ground-water development after 1980. The third alternative would allow irrigable but unirrigated land to be developed at an annual rate of 2, 5, and 8 percent and to apply irrigation water at 80, 100, and 120 percent of consumptive irrigation requirements. The maximum projected declines by 2020 are 119 and 139 feet, respectively, for the second and third alternatives.

A multiple linear-regression model was used to synthesize data for the years 1961 through 1977, when power data were not available. The model used a relation between ground-water pumpage and climatic indexes to develop a full suite of pumpage data to be used as input to a digital ground-water model, one of the products of the Central Valley Aquifer Project.

The hydrogeologic framework consists of the surficial aquifer, intermediate aquifers (Tamiami-upper Hawthorn and lower Hawthorn-upper Tampa aquifers) and confining beds, Floridan aquifer, and lower confining bed (or base of the Floridan aquifer). The quality of ground water in the surficial and intermediate aquifers is generally good, except in the western (coastal) and southern parts where saltwater intrusion or incomplete flushing of connate water has occurred. The mineral content of ground water generally increases with depth and areally from the northeast towards the west and south. A water budget for the study area shows that an average annual rainfall of 51.0 inches minus an evapotranspiration of 38.0 inches per year and streamflow of 12.5 inches per year leaves 0.5 inch per year of recharge to the surficial aquifer.

One modification, the Santee-Cooper diversion project, caused a twentyfold increase in freshwater inflow to the harbor. The other modification was deepening of the navigation channels in the harbor from 30 to 35 feet below mean low water. After field and model studies indicated that the diversion was the major cause of the increase in the sedimentation rate, plans were made to redivert most of the Santee River water back to its former channel. This report documents a review of existing data and literature that was made to evaluate rediversion as a means of reducing the rate of maintenance dredging. The postrediversion decrease in the rate of maintenance dredging can be estimated only within broad limits because some important questions lack reliable answers. Analysis of available information indicates that rediversion will eventually reduce the rate of maintenance dredging by about 40 to 75 percent. The reduction in the rate of maintenance dredging may be delayed for a decade or more by the gradual removal of accumulated sediment and may be partially offset by the effects of future channel deepening.&nbsp;</p>","language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/wri834198","usgsCitation":"Patterson, G.G., 1983, Effect of the proposed Cooper River rediversion on sedimentation in Charleston Harbor, South Carolina: U.S. Geological Survey Water-Resources Investigations Report 83-4198, vi, 65 p., https://doi.org/10.3133/wri834198.","productDescription":"vi, 65 p.","costCenters":[],"links":[{"id":413781,"rank":3,"type":{"id":36,"text":"NGMDB Index Page"},"url":"https://ngmdb.usgs.gov/Prodesc/proddesc_49178.htm","linkFileType":{"id":5,"text":"html"}},{"id":57927,"rank":2,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/wri/1983/4198/report.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":119735,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/wri/1983/4198/report-thumb.jpg"}],"country":"United States","state":"South Carolina","otherGeospatial":"Charleston Harbor, Cooper River","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"coordinates\": [\n          [\n            [\n              -80.1667,\n              33.5\n            ],\n            [\n              -80.1667,\n              32.6667\n            ],\n            [\n              -79.75,\n              32.6667\n            ],\n            [\n              -79.75,\n              33.5\n            ],\n            [\n              -80.1667,\n              33.5\n            ]\n          ]\n        ],\n        \"type\": \"Polygon\"\n      }\n    }\n  ]\n}","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4adce4b07f02db6866ea","contributors":{"authors":[{"text":"Patterson, G.

The problem of identifying cumulative effects is evident in the Trout Creek drainage, a tributary to the Yampa River in northwestern Colorado, where a number of mines are active and mine expansions are planned. As an evaluation tool, a model was developed and calibrated for the Trout Creek drainage and a reach of the Yampa River main stem. This model uses a series of nodes on the stream network to sum water quantity and quality through the network. The model operates on a monthly basis and uses data from water years 1976 to 1981. Output is mean monthly discharge, dissolved-solids concentration, and dissolved-solids load. Observed data are needed to initiate the model and for model calibration. Some data were extrapolated from records of nearby streamflow-gaging stations. Some nodes within the stream network were for inputs from anticipated mining and were inactive during calibrations. After calibration, these nodes were used to input water discharge at a given dissolved-solids concentration to reflect various future mine configurations.

Increased use of the water resources of the area will have a direct impact on their quantity and quality. As part of 18 surface-water projects, 35 reservoirs have been proposed with a combined total storage of 2.18 million acre-feet, 41% greater than the mean annual outflow from the basin. Three computer models were used to demonstrate methods of evaluating future impacts of reservoir development in the Yampa River basin. Four different reservoir configurations were used to simulate the effects of different degrees of proposed reservoir development. A multireservoir-flow model included both within-basin and transmountain diversions. Simulations indicated that in many cases diversion amounts would not be available for either type of diversion. A corresponding frequency analysis of reservoir storage levels indicated that most reservoirs would be operating with small percentages of total capacities and generally with less than 20% of conservation-pool volumes.

The deposits range in thickness from 0 to more than 4,000 feet and overlie the upper Mya zone of the San Joaquin Formation of Pliocene age. Some features of their base reflect structural deformation during Quaternary time. Many freshwater fossils occur in the Tulare Formation itself, including the largest fossil assemblage of clams and snails known on the Pacific Coast. Sediments in the Tulare Formation and other continental deposits consist mainly of unconsolidated deposits of clay, silt, sand, and gravel. Texture maps of the Tulare Formation and other continental deposits show the distribution, both laterally and vertically, of the coarse- and fine-grained sediment in the area. Such maps can be used by water managers for selecting areas for recharge and discharge operations and by ground-water modelers for assigning relative values of hydraulic conductivity and storage coefficient.&nbsp;</p>","language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/wri834000","usgsCitation":"Page, R.W., 1983, Geology of the Tulare Formation and other continental deposits, Kettleman City area, San Joaquin Valley, California, with a section on ground-water management considerations and use of texture maps: U.S. Geological Survey Water-Resources Investigations Report 83-4000, Report: iv, 24 p.; 2 Plates: 21.67 x 24.81 inches and 18.84 x 19.65 inches, https://doi.org/10.3133/wri834000.","productDescription":"Report: iv, 24 p.; 2 Plates: 21.67 x 24.81 inches and 18.84 x 19.65 inches","costCenters":[],"links":[{"id":411591,"rank":5,"type":{"id":36,"text":"NGMDB Index Page"},"url":"https://ngmdb.usgs.gov/Prodesc/proddesc_35648.htm","linkFileType":{"id":5,"text":"html"}},{"id":57860,"rank":2,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/wri/1983/4000/report.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":57859,"rank":4,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/wri/1983/4000/plate-2.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":57858,"rank":3,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/wri/1983/4000/plate-1.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":118805,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/wri/1983/4000/report-thumb.jpg"}],"country":"United States","state":"California","otherGeospatial":"Kettleman City area","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"coordinates\": [\n          [\n            [\n              -120.098,\n              36.158\n            ],\n            [\n              -119.25,\n              36.158\n            ],\n            [\n              -119.25,\n              35.5\n            ],\n            [\n              -120.098,\n              35.5\n            ],\n            [\n              -120.098,\n              36.158\n            ]\n          ]\n        ],\n        \"type\": \"Polygon\"\n      }\n    }\n  ]\n}","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4acce4b07f02db67e40f","contributors":{"authors":[{"text":"Page, R.

This report is one of a series presenting hydrologic information of the High Plains aquifer in Oklahoma.\r\nThe predevelopment to 1980 water-level changes in the High Plains regional aquifer in Oklahoma are shown for Harper, Ellis, Woodward, Dewey, and Roger Mills Counties, on the east, and for the Oklahoma Panhandle, consist- ing of Cimarron, Texas, and Beaver Counties, on the west. About 1,470 water-level measurements in the Panhandle were used in compiling the predevelopment water-table map (Havens, 1982c). In the remaining area to the east about 150 water-level measurements from the 1950's to the 1970's are representative of predevelopment water levels. For the 1980 water-table map, about 330 measurements were made in the Panhandle and about 350 measurements in the eastern area by the Oklahoma Water Resources Board (Havens, 1982b).","language":"ENGLISH","publisher":"U.S. Geological Survey,","doi":"10.3133/wri834073","usgsCitation":"Havens, J., 1983, Water-level changes in the high plains regional aquifer, northwestern Oklahoma, predevelopment to 1980: U.S. Geological Survey Water-Resources Investigations Report 83-4073, 1 map :col. ;on sheet 82 x 58 cm., https://doi.org/10.3133/wri834073.","productDescription":"1 map :col. ;on sheet 82 x 58 cm.","costCenters":[],"links":[{"id":158879,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/usgs_thumb.jpg"},{"id":56461,"rank":400,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/wri/1983/4073/plate-1.pdf","linkFileType":{"id":1,"text":"pdf"}}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e49e6e4b07f02db5e7761","contributors":{"authors":[{"text":"Havens, J.S.","contributorId":12043,"corporation":false,"usgs":true,"family":"Havens","given":"J.S.","email":"","affiliations":[],"preferred":false,"id":198375,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}
