A digital model of the ground water/surface-water system was stressed with recharge and withdrawal functions determined from a linear reservoir model of the soil zone.</p><p>The geohydrologic system includes a regional aquifer which containssand and gravel ranging in age from Pliocene through Pleistocene. The regional aquifer is unconfined in the western part of the watershed and confined in the eastern part. The confining layer, or blue clay, in the east is of Pleistocene age and comprises principally saturated eolian silts with very fine sand interbeds overlying a basal lacustrine clay. Where unconfined conditions exist in the regional aquifer, perennial flow of Willow Creek is sustained principally by ground-water discharge. Where confined conditions exist, the low hydraulic conductivity of the blue clay effectively isolates the regional aquifer from Willow Creek.</p><p>The stream-aquifer models were tested by comparing simulated against measured water levels and streamflow during 1975 and 1976. Agreement between simulated and observed values was obtained by modifying initial estimates of aquifer hydraulic conductivity and specific storage.</p><p>Future ground-water discharge to Willow Creek (base flow) was simulated by super-imposing different patterns of ground-water withdrawals upon variations from average recharge for a monthly climatic sequence identical with the period 1931 to 1954. Frequency analyses of the simulated monthly base flows showed that they would be less than 12 feet<sup>3</sup> per second at least 50 percent of the time under all but completely undeveloped conditions. Simulated water-level declines in the regional aquifer at the end of the pumping season after a drought period similar to that of the 1930's were less than 5 feet where unconfined conditions exist and were more than 80 feet where confined conditions exist. </p>","language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/wri7867","collaboration":"Prepared in cooperation with Lower Elkhorn Natural Resources District and Conservation and Survey Division, Institute of Agriculture and Natural Resources, the University of Nebraska-Lincoln","usgsCitation":"Dugan, J.T., and Lappala, E.G., 1978, Predictive analyses of ground-water discharges in the Willow Creek Watershed, northeast Nebraska: U.S. Geological Survey Water-Resources Investigations Report 78-67, v, 66 p., https://doi.org/10.3133/wri7867.","productDescription":"v, 66 p.","costCenters":[],"links":[{"id":363537,"rank":2,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/wri/1978/0067/report.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":157351,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/wri/1978/0067/report-thumb.jpg"}],"country":"United States ","state":"Nebraska","otherGeospatial":"Willow Creek watershed","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -97.97744750976562,\n              41.964085349226664\n            ],\n            [\n              -97.24067687988281,\n              41.964085349226664\n            ],\n            [\n              -97.24067687988281,\n              42.36919824433563\n            ],\n            [\n              -97.97744750976562,\n              42.36919824433563\n            ],\n            [\n              -97.97744750976562,\n              41.964085349226664\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a18e4b07f02db605281","contributors":{"authors":[{"text":"Dugan, Jack T.","contributorId":102456,"corporation":false,"usgs":true,"family":"Dugan","given":"Jack","email":"","middleInitial":"T.","affiliations":[],"preferred":false,"id":197175,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Lappala, Eric G.","contributorId":23182,"corporation":false,"usgs":true,"family":"Lappala","given":"Eric","email":"","middleInitial":"G.","affiliations":[],"preferred":false,"id":197174,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

These quadrangles are in southwest New Mexico and include the well-known mineral deposits of the Silver City area. The sampling was designed to gain semidetailed information on the metal-anomaly characteristics of the strongly mineralized area surrounding Silver City, New Mexico, and to seek geochemical clues for the continuation of these mineral deposits beneath overlying Tertiary volcanic rocks to the north.&nbsp;</p><p>The data obtained within areas of known mineral deposits provide information on the metallogenic processes and metal suites that both relate and distinguish metal systems. Evaluation of this information relative to the regional geologic framework and the distribution of known mineral deposits will result in the identification of additional target areas for exploration, as well as further our understanding of the geochemical characteristics of mineralized areas. Extrapolation of models developed from the study of areas of known, exposed mineralization to areas covered by Tertiary volcanic rocks, such as the northern part of this tier of quadrangles, is a promising procedure for continuing research into geochemical-anomaly characteristics of covered mineral deposits.&nbsp;</p><p>Preliminary interpretation of the data indicates that the southern part of the area in which Paleozoic-Mesozoic rocks and mineral deposits are exposed, should be reassessed to the classification and genesis of some of the deposits and to the types of mineral commodities that may be present. Some wholly new exploration targets within these areas are also indicated by some of the data. In addition, geochemical clues to buried mineral deposits, possibly representing continuation northward of some features of the Silver City mining district, have been observed in data from the northern, Tertiary volcanic areas. The meanings of these clues are still speculative.</p><p>For this study, 917 stream-sediment and 921 stream-sediment concentrate samples were collected. The stream-sediment-concentrate samples, which consist of heavy minerals, were split into magnetic and nonmagnetic fractions, each of which was analyzed. This resulted in the analysis of 1,842 heavy-mineral and 917 sieved stream-sediment samples.&nbsp;</p><p>Analytical results for all of the sample types are summarized statistically on table 1 and

Force levels throughout bridges and mathematical model parameters are found from hypothetical strong motions for two example bridges. The fourth section describes how digitized records can be analyzed. A linear least-squares fitting procedure in the time domain for identifying mathematical model parameters from recorded strong motions is described. Hypothetical motions for three example bridges are analyzed using this procedure to yield best-fit mathematical models. The last section consists of appendices.

The profile model is able to simulate confined or unconfined aquifers with nonhomogeneous anisotropic hydraulic conductivity, nonhomogeneous specific storage and porosity, and nonuniform saturated thickness. An aquifer may be simulated under either steady or nonsteady flow conditions provided that the ground-water flow path along which the longitudinal axis of the model is oriented does not move in the aquifer during the simulation time period. The profile model parameters are more difficult to quantify than are the corresponding parameters for an areal-oriented water-fluality model. However, the sensitivity of the profile model to the parameters may be such that the normal error of parameter estimation will not preclude obtaining acceptable model results. Although the profile model has the advantage of being able to simulate vertical flow and water-quality changes in a single- or multiple-aquifer system, the types of problems to which it can be applied is limited by the requirements that (1) the ground-water flow path remain oriented along the longitudinal axis of the model and (2) any subsequent hydrologic factors to be evaluated using the model must be located along the land-surface trace of the model. Simulation of hypothetical ground-water management practices indicates that the profile model is applicable to problem-oriented studies and can provide quantitative results applicable to a variety of management practices. In particular, simulations of the movement and dissolved-solids concentration of a zone of degraded ground-water quality near Barstow, Calif., indicate that halting subsurface disposal of treated sewage effluent in conjunction with pumping a line of fully penetrating wells would be an effective means of controlling the movement of degraded ground water.","language":"ENGLISH","publisher":"Dept. of the Interior, Geological Survey : for sale by the Supt. of Docs., U.S. Govt.

These data along with similar data from the Sierra Nevada and along the San Andreas fault system permit a reconstruction of basement rocks offset by the Cenozoic lateral faulting along both the San Andreas and Garlock fault systems. \r\n\r\nThe location of the line of initial 87Sr/ 86 Sr = 0.7060 can be related to the edge of the Precambrian continental crust in the western United States. Our model explains the present configuration of the edge of Precambrian continental crust as the result of two stages of rifting that occurred about 1,250 to 800 m.y. ago, during Belt sedimentation, and about 600 to 350 m.y. ago, prior to and during the development of the Cordilleran geosyncline and to left-lateral translation along a locus of disturbance identified in the central Mojave Desert. The variations in Rb, Sr, and initial 87Sr/ 86 Sr of the Mesozoic granitic rocks are interpreted as due to variations in composition and age of the source materials of the granitic rocks. The variations of Rb, Sr, and initial 87Sr/ 86 Sr in Mesozoic granitic rocks, the sedimentation history during the late Precambrian and Paleozoic, and the geographic position of loci of Mesozoic magmatism in the western United States are related to the development of the continental margin and different types of lithosphere during rifting.","language":"ENGLISH","publisher":"U.S. Govt.

There are two programs. One is for plane strain motions, that is, motions in the plane perpendicular to the long axis of the structure, and the other is for antiplane strain motions, that is motions parallel to the axis. The seismic input is provided by specifying what the motion of the rock-soil boundary would be if the soil were absent and the boundary were a free surface. This may be done by supplying a magnetic tape containing the values of particle velocity for every boundary point at every instant of time. Alternatively, a punch card deck may be supplied giving acceleration values at every instant of time. In the plane strain program it is assumed that the acceleration values apply simultaneously to every point on the boundary; in the antiplane strain program it is assumed that the acceleration values characterize a plane shear wave propagating upward in the underlying elastic medium at a specified angle with the vertical. The nonlinear hysteretic behavior of the soil is represented by a three-dimensional rheological model. A boundary condition is used which takes account of finite rigidity in the elastic substratum. The computations are performed by an explicit finite-difference scheme that proceeds step by step in space and time. Computations are done in terms of stress departures from an unspecified initial state. Source listings are provided here along with instructions for preparing the input. A more detailed discussion of the method is presented elsewhere.","language":"ENGLISH","publisher":"U.S. Geological Survey,","doi":"10.3133/ofr78287","usgsCitation":"Joyner, W.B., 1978, FORTRAN programs for calculating nonlinear seismic ground response in two dimensions: U.S. Geological Survey Open-File Report 78-287, 69 leaves :ill. ;28 cm.; (73 p. - PGS), https://doi.org/10.3133/ofr78287.","productDescription":"69 leaves :ill. ;28 cm.; (73 p. - PGS)","costCenters":[{"id":237,"text":"Earthquake Science Center","active":true,"usgs":true},{"id":379,"text":"Menlo Park Science Center","active":false,"usgs":true}],"links":[{"id":126475,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/ofr_78_287.gif"},{"id":111002,"rank":100,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/of/1978/0287/","linkFileType":{"id":5,"text":"html"}}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a06e4b07f02db5f88d6","contributors":{"authors":[{"text":"Joyner, W.

Two networks of precise horizontal control were established in Mexicali Valley by the U.S. Geological Survey in 1977-78 to measure both types of movement as they occur. These networks consisted of (1) a regional trilateration net brought into the mountain ranges west of the geothermal area from survey stations on an existing U.S. Geological Survey crustal-strain network north of the international border, and (2) a local net tied to stations in the regional net and encompassing the area of present and planned geothermal production. Survey lines in this net were selected to span areas of probable ground-surface movements in and around the geothermal area.</p><p>Electronic distance measuring (EDM) instruments, operating with a modulated laser beam, were used to measure the distances between stations in both networks. The regional net was run using a highly precise long-range EDM instrument, helicopters for transportation of men and equipment to inaccessible stations on mountain peaks, and a fixed wing airplane flying along the line of sight. Precision of measurements with this complex long-range system approached 0.2 parts per million of line length. The local net was measured with medium range EDM instrument requiring minimal ancillary equipment.

At the disposal site, wastewater is stored in two 850-acre (344-ha) lagoons and then spray-irrigated on crop land. About 70 miles (105 km) of drainage tile, which underlies the irrigated land, has caused the water table to be lowered substantially. The decline in water levels has been partially offset by irrigation and leakage from the lagoons; at some places the water table is higher than it was prior to construction. Predictive simulations by the model were used to study the effects of varying tile drainage, amount of irrigation water applied, lagoon leakage, and natural ground-water recharge. If the effectiveness of the tile to collect drainage is reduced by 75 percent, large areas within the wastewater site would become waterlogged.

In a 400-square-mile area directly north and east of Johnstown, rainfall totals of 6 to 12 inches were measured in a six to eight-hour period. Flood peaks having recurrence intervals greater than 100 years were recorded at several sites, primarily in the Conemaugh River basin. Runoff rates were as high as 2,390 cubic feet per second per square mile, in a 5.86-square-mile drainage area in the Little Conemaugh River basin. The Conemaugh River at Seward, which drains 715 square miles, had a peak discharge of 161 cubic feet per second per square mile. The flood waters claimed at least 78 lives and caused total losses in excess of $300 million. Also, seven earthfill dams, used mainly for water supply in the Johnstown area, failed. This report describes the storm and the associated flooding. A tabulation of peak gage heights and discharges for the July 1977 flood and for the maximum flood previously known is included for 57 sites. Data pertaining to the dams that failed are included also.

In this study we have synthesized the results of previous geologic, geophysical, geochemical, and hydrologic investigations of the Long Valley area to develop a generalized conceptual and mathematical model which describes the gross features of heat and fluid flow in the hydrothermal system. \r\n\r\nCenozoic volcanism in the Long Valley region began about 3.2 m.y. (million years) ago and has continued intermittently until the present time. The major event that resulted in the formation of the Long Valley caldera took place about 0.7 m.y. ago with the eruption of 600 km 3 or more of Bishop Tuff of Pleistocene age, a rhyolitic ash flow, and subsequent collapse of the roof of the magma chamber along one or more steeply inclined ring fractures. Subsequent intracaldera volcanism and uplift of the west-central part of the caldera floor formed a subcircular resurgent dome about 10 km in diameter surrounded by a moat containing rhyolitic, rhyodacitic, and basaltic rocks ranging in age from 0.5 to 0.05 m.y. \r\n\r\nOn the basis of gravity and seismic studies, we estimate an aver- age thickness of fill of 2.4 km above the precaldera granitic and metamorphic basement rocks. A continuous layer of densely welded Bishop Tuff overlies the basement rocks, with an average thickness of 1.4 km; the fill above the welded Bishop Tuff consists of intercalated volcanic flows and tuffs and fluvial and lacustrine deposits. Assuming the average grain density of the fill is between 2.45 and 2.65 g/cm 3 , we calculate the average bulk porosity of the total fill as from 0.11 to 0.21. Comparison of published values of porosity of the welded Bishop Tuff exposed southeast of the caldera with calculated values indicates average bulk porosity for the welded tuff (including fracture porosity) from 0.05 to 0.10. Because of its continuity and depth and the likelihood of significant fracture permeability in the more competent rocks such as the welded tuff, our model of the hydrothermal system assumes that the Bishop Tuff provides the principal hot-water reservoir. However, because very little direct information exists from drill holes below 300 m, this assumption must be considered tentative. \r\n\r\nLong Valley caldera is drained by the Owens River and several tributaries which flow into Lake Crowley in the southeast end of the caldera. Streamflow and springflow measurements for water years 1964-74 indicate a total inflow to Lake Crowley of about 10,900 L/s. In contrast, the total discharge of hot water from the hydrothermal reservoir is about 300 L/s. For modeling purposes, the ground-water system is considered as comprising a shallow subsystem in the fill above the densely welded Bishop Tuff containing relatively cold ground water, and a deep subsystem or hydrothermal reservoir in the welded tuff containing relatively hot ground water. Hydrologic, isotopic, and thermal data indicate that recharge to the hydrothermal reservoir occurs in the upper Owens River drainage basin along the western periphery of the caldera. Temperature profiles in a 2.11- km-deep test well drilled by private industry in the southeastern part of the caldera suggest that an additional flux of relatively cool ground water recharges the deep subsystem around the northeast rim. Flow in the shallow ground-water subsystem is neglected in the model except in recharge areas and along Hot Creek gorge, where approximately 80 percent of the hot-water discharge from the hydrothermal reservoir moves upward along faults toward springs in the gorge. \r\n\r\nHeat-flow data from the Long Valley region indicate that the resurgent dome overlies a residual magma chamber more circular in plan than the original magma chamber that supplied the Bishop Tuff","language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/pp1044A","usgsCitation":"Sorey, M., Lewis, R.E., and Olmsted, F.H., 1978, The hydrothermal system of Long Valley Caldera, California: U.S. Geological Survey Professional Paper 1044, Report: 60 p.; 1 Plate: 34.00 x 25.00 inches, https://doi.org/10.3133/pp1044A.","productDescription":"Report: 60 p.; 1 Plate: 34.00 x 25.00 inches","costCenters":[],"links":[{"id":33842,"rank":2,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/pp/1044a/report.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":104540,"rank":4,"type":{"id":36,"text":"NGMDB Index Page"},"url":"https://ngmdb.usgs.gov/Prodesc/proddesc_4695.htm","linkFileType":{"id":5,"text":"html"},"description":"4695"},{"id":33841,"rank":3,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/pp/1044a/plate-1.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":117933,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/pp/1044a/report-thumb.jpg"}],"country":"United States","state":"California","otherGeospatial":"Long Valley Caldera","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"coordinates\": [\n          [\n            [\n              -119.0969,\n              37.7778\n            ],\n            [\n              -119.0969,\n              37.5\n            ],\n            [\n              -118.635,\n              37.5\n            ],\n            [\n              -118.635,\n              37.7778\n            ],\n            [\n              -119.0969,\n              37.7778\n            ]\n          ]\n        ],\n        \"type\": \"Polygon\"\n      }\n    }\n  ]\n}","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a86e4b07f02db64da25","contributors":{"authors":[{"text":"Sorey, M.L.","contributorId":73185,"corporation":false,"usgs":true,"family":"Sorey","given":"M.L.","affiliations":[],"preferred":false,"id":152712,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Lewis, Robert Edward","contributorId":73595,"corporation":false,"usgs":true,"family":"Lewis","given":"Robert","email":"","middleInitial":"Edward","affiliations":[],"preferred":false,"id":152713,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Olmsted, F.
