Test drilling based on conceptual models of ground-water occurrence in carbonate-rock aquifers indicate that multimillion-gallon-per-day supplies could be developed from strategically located production wells in the Shiloh and Overall Creek localities. The Shiloh locality which encompasses an elongated synclinal depression in the bedrock has the potential to supply 5 to 8 million gallons per day. The Overall Creek locality which straddles a joint-oriented lineament has the potential to supply 3 to 6 million gallons per day. Some local springs could be used as a supplemental source of potable water, but storage facilities would be needed to offset poorly sustained flows during dry periods. An exception is Fox Camp Spring which appears to be a natural well. The quality of ground water in the Murfreesboro area is typically hard, moderately mineralized and moderately to highly alkaline. Although the shallowest aquifers are subject to bacterial contamination from the land surface, aquifers beneath a depth of 100 feet are prone to yield potable water.

Differences between the computed and measured potentiometric surface were generally less than 3 feet, with a maximum error of 15 feet. The calibrated model may be used as a predictive tool.

A linear combination of these equations leads to a parametric equation of characteristic form, which consists of two parts: total differentiation along the bicharacteristics and partial differentiation in space. For its numerical solution, the specified-time-interval scheme has been used. The unknown, partial space-derivative terms can be eliminated first by suitable combinations of difference equations, converted from the corresponding differential forms and written along four selected bicharacteristics and a streamline. Other unknowns are thus made solvable from the known variables on the current time plane. The computation is carried to the second-order accuracy by using trapezoidal rule of integration. Means to handle complex boundary conditions are developed for practical application. Computer programs have been written and a mathematical model has been constructed for flow simulation. The favorable computer outputs suggest further exploration and development of model worthwhile.

The Sonoma Volcanics are the principal water-bearing materials in the lower Milliken-Sarco-Tulucay Creeks area, which occupies about 15 square miles (39 square kilometers) in and east of Napa, Calif. The distribution and composition of these volcanic units are highly variable and complex. Within the Sonoma Volcanics the tuffs constitute the best ground-water reservoir. They are principally pumicitic ash-flow tuffs, partly welded and moderately permeable. These tuffs extend to a depth exceeding 500 feet (150 meters), and are irregularly interbedded with clay, igneous flows, and other volcanically derived material of very low permeability which locally confine the tuffs. Recharge and movement of ground water within these tuffs are affected by the highly variable character of this rock sequence, by adjacent formations, and by tectonic features such as the Cup and Saucer ridge and the Soda Creek fault. The lithology of the area limits specific yields to about 4 percent (unconfined conditions). Specific capacities of wells average less than 3 gallons per minute per foot of drawdown (0.6 liter per second per meter) except in the most permeable areas.

\n

Annual pumpage of 3,000 acre-feet (3.7 cubic hectometers), mostly from the Sonoma tuffs, represents a significant portion of the ground-water discharge. The seasonal change in ground-water storage was about 6,600 acre-feet (8.1 cubic hectometers) in 1975. Water-level data from the area reflect the seasonal change in ground-water storage, with fluctuations of 3 to 60 feet (1 to 18 meters). The storage capacity to a depth of 500 feet (150 meters) may be as much as 196,000 acre-feet (242 cubic hectometers) in the study area, but physical and economic factors may restrict the usable capacity to about 20,000 acre-feet (25 cubic hectometers).

\n

Recharge within the area is generally inadequate to marginal under 1975 demand. There is insufficient recharge in the Milliken and Sarco Creeks area to support 1975 pumpage. Long-term changes in the seasonal peak water levels indicate an average decline of 1.5 feet per year (0.5 meter per year). By 1975 annual pumpage was not exceeding recharge in the Tulucay Creek area. Although a downward trend in water levels was noted in the western part of this basin in the late 1940's, the pumping distribution and its stress on the ground-water system have since changed, and no overall downward trend was evident in the Tulucay Creek area in 1975.

Simulation studies were made of flow and sediment transport for the Atchafalaya River basin, Louisiana using a mathematical model calibrated and supplied by the Hydrologic Engineering Center and the New Orleans District, U.S. Army Corps of Engineers. The study results are based on three, 50-year computer simulations for the following alternatives: (1) no-action alternative, (2) channelization with a center-channel flow area of 80,000 sq ft, and (3) channelization with a center-channel flow area of 100,000 sq ft. Analyses of the simulated data base for depth-frequency, inundated-area, floodway cross-section and water-surface profile relationships were made for 10 flow rates. The analyses indicate a general trend of aggradation in the lower part of the floodway with a consequent trend toward increasing the inundated area, especially at higher flood flows.

The Pineland Sands area consists of 770 square miles of surficial glacial outwash, which is undergoing increasing ground-water development for irrigation. The aquifer material is commonly very fine sand to fine gravel, and grain size generally increases from south to north. Thickness, transmissivity, and theoretical well yields are highest in the northern part. In places, saturated thickness exceeds 100 feet, transmissivity exceeds 20,000 feet squared per day, and expected well yields exceed 2,000 gallons per minute.

\n

Water in the aquifer is chemically suitable for irrigation. It is calcium bicarbonate water generally containing dissolvedsolids concentrations of 100-300 milligrams per liter.

\n

An estimated long-term water budget for the aquifer involves inflow and outflow of 295 cubic feet per second. Over 80 percent of recharge to the aquifer is directly from snowmelt and spring rain; the remainder is from underflow across the northern boundary of the aquifer and locally from streams and lakes. Over 90 percent of discharge from the aquifer is flow to streams and lakes; the remainder is through evapotranspiration.

\n

A mathematical model of the surficial aquifer was made to facilitate analysis of the hydrologic system. The model was calibrated through simulation of the natural ground-water flow system. Subsequent applications of the model to estimate effects of future ground-water development indicate that much of the system can safely support long-term, large-scale withdrawals.

\n

Results of model analysis show that present development (withdrawals totaling 3.3 cubic feet per second) has no significant effect on the aquifer system. Simulations of hypothetical withdrawals of 60 to 120 cubic feet per second resulted in computed water-table declines as great as 12 feet in places. Most pumpage is derived from intercepted base flow to streams, thus reducing streamflow. Similarly, some lake levels can be expected to decline in response to nearby intensive development.

The stream circuits of an electric analog model of the ground-water system of Long Island were modified to more accurately represent the relationahip between streamflow and ground-water levels. Assumptions for use of the revised circuits are (1) that streams are strictly gaining, and (2) that ground-water seepage into the streams is proportional to the difference between streambed elevation and the average water-table elevation near the stream. No seepage into streams occurs when ground-water levels drop below the streambed elevation. Regional simulation of the 1962-68 drought on Long Island was significantly improved by use of the revised stream circuits.

The Iaygia quadrangle, in the equatorial region of Mars just north of the Hellas basin, is mainly ancient, hilly, and cratered upland terrain. The southern one-third of the quadrangle is dominated by mountains and knobby materials representing mountains of pre-Hellas material and material related to the Hellas basin and mappable in a 500-km-wide zone circumjacent to it. The northeast quadrant of the quadrangle contains two large arcuate structural scarps and moderately low-albedo mountain material and knobby deposits, both associated with formation of the Isidis basin (Meyer and Grolier, 1977). The major part of the Iapygia quadrangle is mapped as hilly and cratered upland materials units with subordinate various plains deposits. Although the southern rim of the Syrtis Major basin coincides with the northern margin of the quadrangle along the equator from 285˚ to 295˚ W., no structural features or ejecta associated with the basin have been identified in either the Iaypgia or Syrtis Major (MC-13) quadrangle. A dominant feature of the landscape with Iaypgia is the 475-km-diameter basin-crater Huygens, which shows subtle evidence of having an inner ring structure (Wilhelms, 1973). A second basin-sized crater, Schroeter (265-km-diameter), shares its northern rim with the Syrtis Major quadrangle (MC-13) and has a more distinct inner ring structure than Huygens.

Lajas Valley is plagued with salinity and waterlogging problems of the soils. Use of brackish (500 milligrams per liter) ground water for irrigation compounded the problem until an irrigation-drainage system was constructed in 1955.

Lajas Valley is an alluvium-filled trough between volcanic and limestone highlands. The alluvium, mostly clay and as much as 300 feet (90 meters) thick, contains brackish ground water except in the recharge areas located along the foothills. Artesian conditions exist in the eastern part of the valley where upward hydraulic gradients have increased due to the addition of irrigation water in the recharge areas.

Wells yield up to 200 gallons per minute (13 liters per second) from alluvial fan deposits in the recharge areas. Wells tapping the buried limestone aquifer in the northwest will yield as much as 2,000 gallons per minute (126 liters per second).

Results from a digital models show that a network of discharge wells could alleviate waterlogging of the soils in the artesians

The proposed Great Bear wilderness has a good potential for oil and gas (mainly gas), and a moderate potential for submarginal resources of copper and silver in a belt 25 miles (40 km) long and about 1 mile (1.6 km) wide that is partly within the study area along the western boundary. The eastern part of the area may contain small submarginal resources of coal. Sand and gravel, dimension stone, and high calcium limestone are in the area, but they occur in abundance in more accessible areas elsewhere in northwest Montana. The potential for geothermal resources is nil.

A mineral survey of the proposed Great Bear wilderness was made in 1974 and 1976. The work by the U.S. Geological Survey consisted of geologic mapping, and geochemical and geophysical surveys. The U.S. Bureau of Mines made a courthouse search for mining claims, and sampled and mapped prospects.

Precambrian sulfide deposits in the Southern Rocky Mountains in Colorado are being studied and re-evaluated according to geologic concepts which were developed in recent years in other parts of the world during successful research regarding economic massive sulfide deposits. These studies, initiated in 1974 in Colorado by the U.S. Geological Survey, have indicated that a new look at areas containing long dormant mines and prospects may well lead to the discovery of minable Precambrian sulfide deposits. The zinc, copper, and lead contents of ores investigated to date, supplemented by silver and gold contents, indicate that many long-forgotten deposits are minable in terms of grade. The deposits occur in Precambrian rocks metamorphosed to the lower amphibolite facies in one major region and to the upper amphibolite facies in other regions. Field studies have provided ample evidence indicating that the search for commercial tonnages can he facilitated by using newer concepts of economic geology regarding ore-host rock associations as prospecting guides and by using structural considerations aimed toward learning how metamorphism and folding have modified the shapes and distribution of the ore bodies. A newly recognized concept, originating from the current studies by the U.S. Geological Survey in Colorado, concerns the potential economic significance of gahnite, a zinc spinel. The field and laboratory data indicate that gahnite can be used by geologists as a prospector's guide to ore and can be considerd by mining engineers as a potential major ore mineral, contributing significant amounts of zinc to the sulfide ores in many of the deposits. Studies to date indicate that the Gunnison area, the Salida area, and the Guffey area are particularly favorable to the search for minable deposits, and the potential is equally present in many other areas.

The Mekong River, one of the world's largest rivers, flows through Cambodia. Also, the Tonle Sap (Grand Lac), a highly productive fresh-water lake, functions as a huge off-channel storage reservoir for flood flow of the Mekong River. Surfacewater discharge in streams and rivers of Cambodia is abundant during the wet season, mid-May through mid-November, when 85 percent of the precipitation falls, but is frequently deficient during the remainder of the year. Annual rainfall ranges from 1,370 mm in the central lowlands to more than 5,000 mm in the mountainous highlands. The mean annual temperature for the country is 27.5?C and the evaporation rate is high. \r\n\r\nDuring 1960-63, 1,103 holes were drilled in 16 of the 18 khets (provinces), of which 795 or approximately 72 percent, were productive wells at rates ranging from 1.1 to 2,967 l/min. The productive wells ranged in depth from 2 to 209.4 m and were 23.2 m deep on the average. \r\n\r\nMr. Rasmussen ' studied the subsurface geology of Cambodia in considerable detail by examining drillers' logs and constructing nine geologic cross sections. The principal aquifer tapped by drilled wells in Cambodia is the Old Alluvium. In many places, however, dug wells and a few shallow drilled wells obtain water from the Young Alluvium. Sandstone of the Indosinias Formation yields moderate to small quantities of water to wells in a number of places. Also, wells tapping water-bearing basalt have a small to moderate yield. The quality of water is recorded in only a few analyses. The dissolved solids concentrations appear to be generally low so that the water is usable for most purposes without treatment. Some well waters, however, are high in iron and would have to be aerated and filtered before use. In this report, well records are tabulated, and the geology and hydrology is discussed by khets. The bulk of the available information is on the central lowlands and contiguous low plateaus, as the mountainous areas on the west and the high plateaus on the east are relatively unexplored with respect to their ground-water availability. \r\n\r\nNo persistent artesian aquifer has been identified nor have any large potential ground-water sources been found .although much of the country yet remains to be explored by test drilling. Well irrigation for garden produce is feasible on a modest scale in many localities throughout Cambodia. It does not seem likely, however, that large-scale irrigation from wells will come about in the future. Ground water may be regarded as a widely available supplemental source to surface water for domestic, small-scale industrial, and irrigation use.","language":"ENGLISH","publisher":"U.S. Govt. Print.

Field-study methods were of a reconnaissance nature, and thus the interpretations in the report are tentative. \r\n\r\nLandscape of the Metlakatla Peninsula, on which the city of Metlakatla is located, is characterized by a muskeg-covered terrane of very low relief. In contrast, most of the rest of Annette Island is composed of mountainous terrane with steep valleys and numerous lakes. During the Pleistocene Epoch the Metlakatla area was presumably covered by ice several times; glaciers smoothed the present Metlakatla Peninsula and deeply eroded valleys on the rest. of Annette Island. The last major deglaciation was completed probably before 10,000 years ago. Rebound of the earth's crust, believed to be related to glacial melting, has caused land emergence at Metlakatla of at least 50 ft (15 m) and probably more than 200 ft (61 m) relative to present sea level.\r\n\r\nBedrock in the Metlakatla area is composed chiefly of hard metamorphic rocks: greenschist and greenstone with minor hornfels and schist. Strike and dip of beds are generally variable and minor offsets are common. Bedrock is of late Paleozoic to early Mesozoic age. Six types of surficial geologic materials of Quaternary age were recognized: firm diamicton, emerged shore, modern shore and delta, and alluvial deposits, very soft muskeg and other organic deposits, and firm to soft artificial fill. A combination map unit is composed of bedrock or diamicton. Geologic structure in southeastern Alaska is complex because, since at least early Paleozoic time, there have been several cycles of tectonic deformation that affected different parts of the region. Southeastern Alaska is transected by numerous faults and possible faults that attest to major movements of the earth's crust. The latest of the major tectonic events in the Metlakatla region occurred in middle Tertiary time; some minor fault activity probably continues today at depth. Along the outer coast of southeastern Alaska and British Columbia, major faulting activity occurs in the form of active, strike-slip movement along the Queen Charlotte fault about 100 mi (160 kin) west-southwest of Metlakatla. Some branching subsidiary faults also may be active, at least one of which may be the Sandspit fault. \r\n\r\nMany major and smaller earthquakes occur along the outer coast. These shocks are related to movements along the Queen Charlotte fault. A few small earthquakes occur in the region between the outer coast and the Coast Mountains, which includes Metlakatla. 0nly a few earthquakes have been reported as felt at Metlakatla; these shocks and others felt in the region are tabulated. Historically, the closest major earthquake was the magnitude 8.1 Queen Charlotte Islands earthquake of August 22, 1949, which occurred along the Queen Charlotte fault 125 mi (200 km) southwest of Metlakatla. No damage was reported at Metlakatla. The probability of destructive earthquakes affecting Metlakatla is unknown. A consideration of the tectonics and earthquake history of the region, however, suggests that sometime in the future an earthquake with a magnitude of about 8 will occur along that segment of the Queen Charlotte fault nearest to Metlakatla. Smaller earthquakes with magnitudes of 6 or more might occur elsewhere in the Metlakatla region or south-southeastward near Dixon Entrance or Hecate Strait. \r\n\r\nSeveral geologic effects that have characterized large earthquakes elsewh6re may be expected to accompany some of the possible major earthquakes that might affect the Metlakatla area in the future. Evaluation of effects indicates that fault displacement and tectonic uplift or subsidence are probably unlikely, and ground shaking in general probably would be strongest","language":"ENGLISH","publisher":"U.S. Geological Survey,","doi":"10.3133/ofr77272","usgsCitation":"Yehle, L.A., 1977, Reconnaissance engineering geology of the Metlakatla area, Annette Island, Alaska, with emphasis on evaluation of earthquakes and other geologic hazards: U.S. Geological Survey Open-File Report 77-272, iv, 93 p. :maps (4 fold.) ;28 cm.; (2 sheets, scale 1:9,600; 2 sheets, scale 1:25,000 - PGS), https://doi.org/10.3133/ofr77272.","productDescription":"iv, 93 p. :maps (4 fold.) ;28 cm.; (2 sheets, scale 1:9,600; 2 sheets, scale 1:25,000 - PGS)","costCenters":[],"links":[{"id":95023,"rank":400,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/of/1977/0272/plate-01.pdf","size":"494","linkFileType":{"id":1,"text":"pdf"}},{"id":95024,"rank":401,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/of/1977/0272/plate-02.pdf","size":"674","linkFileType":{"id":1,"text":"pdf"}},{"id":95025,"rank":402,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/of/1977/0272/plate-03.pdf","size":"542","linkFileType":{"id":1,"text":"pdf"}},{"id":95026,"rank":403,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/of/1977/0272/plate-04.pdf","size":"906","linkFileType":{"id":1,"text":"pdf"}},{"id":95027,"rank":404,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/of/1977/0272/plate-05.pdf","size":"1561","linkFileType":{"id":1,"text":"pdf"}},{"id":95028,"rank":405,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/of/1977/0272/plate-06.pdf","size":"441","linkFileType":{"id":1,"text":"pdf"}},{"id":95029,"rank":406,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/of/1977/0272/plate-07.pdf","size":"542","linkFileType":{"id":1,"text":"pdf"}},{"id":95030,"rank":407,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/of/1977/0272/plate-08.pdf","size":"305","linkFileType":{"id":1,"text":"pdf"}},{"id":95031,"rank":408,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/of/1977/0272/plate-09.pdf","size":"285","linkFileType":{"id":1,"text":"pdf"}},{"id":95032,"rank":409,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/of/1977/0272/plate-10.pdf","size":"224","linkFileType":{"id":1,"text":"pdf"}},{"id":144982,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/of/1977/0272/report-thumb.jpg"},{"id":39664,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/1977/0272/report.pdf","linkFileType":{"id":1,"text":"pdf"}}],"scale":"9600","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a74e4b07f02db6442c3","contributors":{"authors":[{"text":"Yehle, Lynn A. yehle@usgs.gov","contributorId":3794,"corporation":false,"usgs":true,"family":"Yehle","given":"Lynn","email":"yehle@usgs.gov","middleInitial":"A.","affiliations":[],"preferred":true,"id":163717,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}} ,{"id":11808,"text":"ofr77744 - 1977 - Uranium mobility during interaction of rhyolitic glass with alkaline solutions: dissolution of glass","interactions":[],"lastModifiedDate":"2012-02-02T00:06:34","indexId":"ofr77744","displayToPublicDate":"1994-01-01T00:00:00","publicationYear":"1977","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":"77-744","title":"Uranium mobility during interaction of rhyolitic glass with alkaline solutions: dissolution of glass","docAbstract":"This report concerns investigations designed to identify the important physical and chemical parameters influencing the rate of release of uranium from glass shards of rhyolitic air-fall ash. Oxidizing, silica undersaturated, alkaline solutions are eluted through a column of rhyolitic glass shards at a carefully controlled temperature, pressure, and flow rate. The solutions are monitored for the concentration of uranium and selected additional elements (Si, K, Li, F), and the glass is recovered and examined for physical and/or chemical evidence of attack. The flushing mode is designed to mimic leaching of glass shards by intermittent, near-surface waters with which the glass is not in equilibrium. \r\n\r\nReported rates are applicable only to the experimental conditions (120?C, 7,000 psi), but it is assumed that the reaction mechanisms and the relative importance of rate-influencing parameters remain unchanged, at reduced temperature and pressure. Results of the above experiment indicate that silica and uranium are released from glass shards at comparable rates, while lithium and potassium are released faster and fluorine slower than either Si or U. Rates of release of silica and uranium correlate positively with the surface area of the shards. Rhyolitic shards release uranium at faster rates than rhyodacitic shards of comparable surface area. Changes in the shards resulting from experimental treatment and observed in the original glass separates from an Oligocene ash (compared to a Pleistocene ash) include; surface pitting, increased surface area, devitrification rinds (<1l micron wide) and reduced lithium contents. Future investigations will study the effect of temperature, pressure, solution composition, and flow rate on the relative mobility of U, Si, Li, F, and K.","language":"ENGLISH","publisher":"U.S. Geological Survey,","doi":"10.3133/ofr77744","usgsCitation":"Zielinski, R.A., 1977, Uranium mobility during interaction of rhyolitic glass with alkaline solutions: dissolution of glass: U.S. Geological Survey Open-File Report 77-744, 36, [5] leaves of plates :ill. ;28 cm.; (41 p. - PGS), https://doi.org/10.3133/ofr77744.","productDescription":"36, [5] leaves of plates :ill. ;28 cm.; (41 p. - PGS)","costCenters":[],"links":[{"id":145048,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/of/1977/0744/report-thumb.jpg"},{"id":39701,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/1977/0744/report.pdf","linkFileType":{"id":1,"text":"pdf"}}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a18e4b07f02db60541a","contributors":{"authors":[{"text":"Zielinski, Robert A. 0000-0002-4047-5129 rzielinski@usgs.gov","orcid":"https://orcid.org/0000-0002-4047-5129","contributorId":1593,"corporation":false,"usgs":true,"family":"Zielinski","given":"Robert","email":"rzielinski@usgs.gov","middleInitial":"A.","affiliations":[{"id":164,"text":"Central Energy Resources Science Center","active":true,"usgs":true}],"preferred":true,"id":163765,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}} ,{"id":10891,"text":"ofr77276 - 1977 - Application of digital profile modeling techniques to ground-water solute transport at Barstow, California","interactions":[{"subject":{"id":10891,"text":"ofr77276 - 1977 - Application of digital profile modeling techniques to ground-water solute transport at Barstow, California","indexId":"ofr77276","publicationYear":"1977","noYear":false,"title":"Application of digital profile modeling techniques to ground-water solute transport at Barstow, California"},"predicate":"SUPERSEDED_BY","object":{"id":2612,"text":"wsp2050 - 1978 - Application of digital profile modeling techniques to ground-water solute transport at Barstow, California","indexId":"wsp2050","publicationYear":"1978","noYear":false,"title":"Application of digital profile modeling techniques to ground-water solute transport at Barstow, California"},"id":1}],"supersededBy":{"id":2612,"text":"wsp2050 - 1978 - Application of digital profile modeling techniques to ground-water solute transport at Barstow, California","indexId":"wsp2050","publicationYear":"1978","noYear":false,"title":"Application of digital profile modeling techniques to ground-water solute transport at Barstow, California"},"lastModifiedDate":"2012-02-02T00:06:25","indexId":"ofr77276","displayToPublicDate":"1994-01-01T00:00:00","publicationYear":"1977","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":"77-276","title":"Application of digital profile modeling techniques to ground-water solute transport at Barstow, California","language":"ENGLISH","publisher":"U.S. Geological Survey,","doi":"10.3133/ofr77276","usgsCitation":"Robson, S.G., 1977, Application of digital profile modeling techniques to ground-water solute transport at Barstow, California: U.S. Geological Survey Open-File Report 77-276, v, 56 leaves :ill., maps ;27 cm., https://doi.org/10.3133/ofr77276.","productDescription":"v, 56 leaves :ill., maps ;27 cm.","costCenters":[],"links":[{"id":143000,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/usgs_thumb.jpg"}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4ac6e4b07f02db67aa1a","contributors":{"authors":[{"text":"Robson, Stanley G.","contributorId":73187,"corporation":false,"usgs":true,"family":"Robson","given":"Stanley","email":"","middleInitial":"G.","affiliations":[],"preferred":false,"id":162152,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}} ,{"id":10854,"text":"ofr77150 - 1977 - A brief investigation of the surface-water hydrology of Yemen Arab Republic","interactions":[],"lastModifiedDate":"2019-04-26T09:10:54","indexId":"ofr77150","displayToPublicDate":"1994-01-01T00:00:00","publicationYear":"1977","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":"77-150","title":"A brief investigation of the surface-water hydrology of Yemen Arab Republic","docAbstract":"Yemen, near the southwest tip of the Arabian Peninsula, is a mountainous country bordered by a desert on the east and a coastal plain on the west.

As part of ongoing research by the U.S. Geological Survey on the geology and resource potential of the Gulf of Alaska Tertiary Province, a vast amount of data has been accumulated over the past 25 years on the lithology and paleontology of bedded rocks in the province. This report brings together available information on the occurrence, age, and paleoecologic, significance of benthonic foraminifers and presents correlations based on these data from 16 measured stratigraphic sections and 12 exploratory wells. Relatively few reports employing modern taxonomic methods developed during the past 40 years have been published on foraminiferal biostratigraphy of the Gulf of Alaska. Reports by Cushman (1941), Cushman and Todd (1947), Tappan (1951), Todd (1953), Loeblich and Tappan (1953), Todd (1957), Rau (1963), Cooper (1964), and Todd and Low (1967) are primarily concerned with taxonomy, ecology and paleoecology, or the geologic age of assemblages from isolated outcrops. Almost no data have been published on foraminiferal correlations of measured sections and wells. The paucity of such information has prompted the synthesis and interpretation of foraminiferal data that provide the framework of correlation presented in this report. Some of the benthonic provincial stages that have been assigned to lower and middle parts of the Tertiary of other west coast areas are recognized for the Gulf of Alaska. Divisions for the upper part of the Tertiary are broad, but specific faunal occurrences are recognized as possible aids to correlations. Regional correlations presented in this report are necessarily broad and may be modified and redefined when new data become available from the current round of exploratory drilling for petroleum in the offshore part of the Gulf of Alaska Tertiary Province.

It is anticipated that this report will be of particular interest to readers associated with petroleum exploration. As a convenience to them and because most foraminiferal data from wells, including those of this report, are from cuttings, all checklists are arranged to show plainly the highest occurrence of each species within each measured section and well. Furthermore, in conformity with these data, all sections and wells are described from the top to bottom. The text describes the stratigraphic and paleoecologic significance of foraminifers by biostratigraphic units and by individual sections and wells.

The principal source of ground water in the basin is a shallow unconfined aquifer in the valley alluvium. Continuous pumping of the shallow aquifer has induced the flow of saltwater and has caused the chloride concentration to increase from about 30 to 540 milligrams per liter in the lower part of the valley. A study from January 1971 to December 1974 indicated that the hydraulic conductivities of the aquifer materials, in the basin, are less than 1 foot per day for the metavolcanic and igneous rocks. Estimated conductivities range from 10 to 100 feet per day for the alluvium. The average transmissivity of the alluvial aquifer is estimated to be 4,000 feet squared per day and the average specific capacity is 20 gallons per minute per foot of drawdown. In December 1974, the alluvial aquifer contained an estimated 10 ,000 acre-feet of water in recoverable storage. The data suggest that water supplies to meet future needs could be supplemented by the construction of surface-water-control structures and additional wells. Analysis of a digital simulation model suggests that wells be located in the upper reaches of the alluvial aquifer where a sustained yield of 3,000 gallons per minute could be obtained.

Fractures and root tubes with chemically oxidized and (or) reduced soil in their walls extend to 3 to 4.5 meters below natural land surface. Preliminary simulations of pressure heads with a digital model suggest that hydraulic conductivity is an order of magnitude greater in the fractured till near land surface than at greater depth. Hydraulic gradients are predominantly downward, even beneath small valleys. The upper part of a body of underlying lacustrine silt is unsaturated; in the lower, saturated part, slow lateral flow may occur. In the older trenches, water began to build up in 1971, overflowed briefly in 1975, and was pumped out in 1975-76. Water levels rose abruptly during major rainstorms in mid-1975, indicating rapid infiltration through cracks in the cover material. The new trenches have maintained low, stable water levels, perhaps because of thicker, more compact cover and less waste settlement; pressure heads near these trenches are low, locally approaching zero, perhaps because of slight infiltration and limited near-surface storage. Peak tritium concentrations in test-hole cores (generally 0.00001 to 0.001 microcuries per milliliter) were found within 3 meters of land surface and are attributed to surface contamination. Concentrations declined rapidly with depth within the fractured till; secondary peaks found at about 9 meters in three holes are attributed to lateral migration from trenches. Other radioisotopes were detected only near land surface. Samples from the walls of shallow fractures revealed no accumulation of radioisotopes.
