Logarithmic transformation and first-order differencing of the data sets were necessary to produce second-order, stationary time series and remove seasonal trends. \r\n\r\nCyclic models accounted for less than 42 percent of the variance in the water series and 31 percent in the sediment series. Analysis of the apparent oscillations of given frequencies occurring in the data indicates that frequently occurring storms can account for as much as 50 percent of the variation in sediment discharge. \r\n\r\nComponents of the frequency analysis indicate that a linear representation is reasonable for the water-sediment system. Models that incorporate lagged water discharge as input prove superior to univariate techniques in modeling and prediction of sediment discharges. The random component of the models includes errors in measurement and model hypothesis and indicates no serial correlation. An index of sediment production within or between drain-gage basins can be calculated from model parameters.","language":"ENGLISH","publisher":"U.S. Geological Survey,","doi":"10.3133/wsp2216","usgsCitation":"Fitzgerald, M.G., and Karlinger, M.R., 1983, Daily water and sediment discharges from selected rivers of the eastern United States; a time-series modeling approach: U.S. Geological Survey Water Supply Paper 2216, vi, 24 p. :ill., 1 map ;27 cm., https://doi.org/10.3133/wsp2216.","productDescription":"vi, 24 p. :ill., 1 map ;27 cm.","costCenters":[],"links":[{"id":137526,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/wsp/2216/report-thumb.jpg"},{"id":26423,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/wsp/2216/report.pdf","linkFileType":{"id":1,"text":"pdf"}}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a96e4b07f02db65acb2","contributors":{"authors":[{"text":"Fitzgerald, Michael G.","contributorId":42942,"corporation":false,"usgs":true,"family":"Fitzgerald","given":"Michael","email":"","middleInitial":"G.","affiliations":[],"preferred":false,"id":143606,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Karlinger, Michael R.","contributorId":10777,"corporation":false,"usgs":true,"family":"Karlinger","given":"Michael","email":"","middleInitial":"R.","affiliations":[],"preferred":false,"id":143605,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

Three drill holes placed to test anomalies within these formations yielded negative results. \r\n\r\nStudies of a long, narrow anomaly north of the Rabathan area indicated a similar geological environment. This northern area also contains limited zones that are highly anomalous in copper and zinc and extensive zones that are slightly anomalous in those metals. Drilling was not undertaken in this area. \r\n\r\nThe Bilajimah airborne electromagnetic anomaly west of Wadi Bidah coincides with a broad synclinorium of layered felsic turfs and gossans. Geochemical studies indicated slightly anomalous copper, zinc, and silver values in gossans within the anomaly area. Two drill holes intersected carbonaceous rock that contained approximately 15 percent pyrrhotite and traces of sphalerite and chalcopyrite. \r\n\r\nTwo geophysically anomalous areas west of Wadi Bidah surround ancient mines at Mahawiyah and Khayal al Masna'ah. Results of geochemical sampling at these workings were positive. An airborne electromagnetic anomaly located in the Assifar area in the southwestern corner of the Wadi Bidah district is underlain principally by metasedimentary rocks that include large linear zones of cherty iron-manganese formation and a few gossans .containing secondary base metal minerals.\r\n\r\nDetailed mapping and sampling of the Mulhal ancient mine, located west of Wadi Bidah, revealed two types of polymetallic gossans : (1) stratiform deposits interlayered with ignimbrites and mafic volcanic rocks and (2) barite-bearing gossanous material in shear zones that grade into hydrothermally altered shear zones and extend beyond the mine area. The gossans and gossanous shear zones contain anomalous amounts of gold, silver, lead, copper, zinc, barium, and selenium. \r\n\r\nTwo gossans west of Wadi Bidah were mapped and sampled in detail; both gossans are interlayered, with siliceous volcanic rocks. Although the gossan at Jabal Mohr covers a large area, it contains low amounts of precious and base metals.

The aquifer overlies a thick clay layer at an average depth of 65 feet. The water table is about 10 feet below land surface in the western part of the Base and about 25 feet below land surface in the eastern part. A ground-water divide cuts diagonally across the Base from northwest to southeast. South of the divide, ground water flows to the Au Sable River; north of the divide, it flows to Van Etten Creek and Van Etten Lake. Mathematical models were used to aid in calculating rates of groundwater flow. Rates range from about 0.8 feet per day in the eastern part of the Base to about 0.3 feet per day in the western part. Models also were used as an aid in making decisions regarding purging of contaminated water from the aquifer. </p><p>In 1977, trichloroethylene was detected in the Air Force Base water-supply system. It had leaked from a buried storage tank near Building 43 in the southeastern part of the Base and moved northeastward under the influence of the natural ground-water gradient and the pumping of Base water-supply wells. In the most highly contaminated part of the plume, concentrations are greater than 1,000 micrograms per liter. Current purge pumping is removing some of the trichloroethylene, and seems to have arrested its eastward movement. Pumping of additional purge wells could increase the rate of removal. </p><p>Trichloroethylene has also been detected in ground water in the vicinity of the Base alert apron, where a plume from an unknown source extends northeastward off Base. A smaller, less well-defined area of contamination also occurs just north of the larger plume. Trichloroethylene, identified near the waste-treatment plant, seepage lagoons, and the northern landfill area, is related to activities and operations in these areas.

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}]}}

Bedrock in the area is shale, siltstone, sandstone, and the McAlester (Stigler) and Hartshorne coals of the McAlester Formation and Hartshorne Sandstone of Pennsylvanian age. The two coal beds, upper and lower Hartshorne, associated with the Hartshorne Sandstone converge or are separated by a few feet or less of bony coal or shale in the McCurtain area. Many small faults cut the Hartshorne coal in all the McCurtain-area mines. The main avenues of water entry to and movement through the bedrock are the exposed bedding-plane openings between layers of sandstone, partings between laminae of shale, fractures and joints developed during folding and faulting laminae of shale, fractures and joints developed during folding and faulting of the brittle rocks, and openings caused by surface mining--the overburden being shattered and broken to form spoil. Water-table conditions exist in bedrock and spoil in the area. Mine pond water is in direct hydraulic connections with water in the spoil piles and the underlying Hartshorne Sandstone.\r\nSulfate is the best indicator of the presence of coal-mine drainage in both surface and ground water in the Oklahoma coal field. Median sulfate concentrations for four sites on Mule Creek ranged from 26 to 260 milligrams per liter. Median sulfate concentrations increased with increased drainage from unreclaimed mined areas. The median sulfate concentration in Mule Creek where it drains the reclaimed area is less than one-third of that at the next site downstream where the stream begins to drain abandoned (unreclaimed) mine lands.\r\n\r\nWater from Mule Creek predominantly is a sodium sulfate type. Maximum and median values for specific conductance and concentrations of calcium, magnesium, sodium, sulfate, chloride, dissolved solids, and alkalinity increase as Mule Creek flows downstream and drains increasing areas of abandoned (unreclaimed) mining lands. Constituent concentrations in Mule Creek, except those for dissolved solids, iron, manganese, and sulfate, generally do not exceed drinking-water limits. Reclamation likely would result in decreased concentrations of dissolved solids, calcium, magnesium, sodium, sulfate, and alkalinity in Mule Creek in the vicinity of the reclaimed area.\r\n\r\nGround water in the area is moderately hard to very hard alkaline water with a median pH of 7.2 to 7.6. It predominately is a sodium sulfate type and, except for dissolved solids, iron manganese, and sulfate, constituent concentrations generally do not exceed drinking-water limits. Ground-water quality would likely be unchanged by reclamation.\r\n\r\nThe quality of water in the two mine ponds is quite similar to that of the shallow ground water in the area. Constituents in water from both ponds generally do not exceed drinking-water limits and the water quality is unlikely to be changed by reclamation in the area.","language":"ENGLISH","publisher":"U.S. Geological Survey,","doi":"10.3133/wri834202","usgsCitation":"Slack, L.J., 1983, Hydrology of an abandoned coal-mining area near McCurtain, Haskell County, Oklahoma: U.S. Geological Survey Water-Resources Investigations Report 83-4202, v, 117 p. :ill., maps ;28 cm., https://doi.org/10.3133/wri834202.","productDescription":"v, 117 p. :ill., maps ;28 cm.","costCenters":[],"links":[{"id":124782,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/wri/1983/4202/report-thumb.jpg"},{"id":58548,"rank":400,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/wri/1983/4202/plate-1.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":58549,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/wri/1983/4202/report.pdf","linkFileType":{"id":1,"text":"pdf"}}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e49dee4b07f02db5e2ef3","contributors":{"authors":[{"text":"Slack, L.

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}]}}

Outflows from the aquifer were 26.7 cubic feet per second to surface water and 2.3 cubic feet per second to wells. A finite-difference ground-water flow model was used to simulate conditions observed in the aquifer during 1981. Model conditions observed in the aquifer during 1981. Model simulations indicate that a 50 percent reduction of average 1981 recharge to the aquifer would cause water level declines of up to 20 feet in some areas. Model simulations of increased pumping at a high yield well in the northern part of the aquifer indicate that resulting changes in the water table will not be sufficient to intercept groundwater contaminated by a sludge disposal site.

Transient-decay voltages in profile mode were measured across the Sha'ab at \r\nTare and Rabathan prospects by use of three transmitterreceiver loop configurations. At the Sha'ab at Tare prospect all of the loop configurations indicated the mineralized \r\nzone. Analysis of the coincident loop data at Sha'ab at Tare reveals that gossanous and altered rock of i0 ohm-m resistivity extends to a depth of 35 m, where there is an unweathered, dry mineralized zone of about 1 ohm-m resistivity. The model further suggests that the rocks at a depth of 55 m and below the water table are even less resistive (0. 1 ohm-m). The TDEM method successfully discriminated conductors within from those below the weathered zone at the Rabathan prospect. Conductors below the weathered zone are identified by a lack of transient response in the early part of the transient decay curve, followed by an increasing response in the middle to late parts of the transient decay curve. Results of these limited tests suggest the potential value of integrating TDEM with other geophysical tools in the Kingdom. Recommendations are made to expand these tests into a more comprehensive program that will evaluate the TDEM potential in various geologic environments that are host to mineral deposits of diverse origin.","language":"ENGLISH","publisher":"U.S. Geological Survey,","doi":"10.3133/ofr83613","usgsCitation":"Flanigan, V.J., Sadek, H., Smith, B., and Tippens, C.L., 1983, Time-domain electromagnetic tests in the Wadi Bidah District, Kingdom of Saudi Arabia: U.S. Geological Survey Open-File Report 83-613, ii, 27 p. ill., maps ;28 cm., https://doi.org/10.3133/ofr83613.","productDescription":"ii, 27 p. ill., maps ;28 cm.","costCenters":[],"links":[{"id":140730,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/of/1983/0613/report-thumb.jpg"},{"id":35040,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/1983/0613/report.pdf","linkFileType":{"id":1,"text":"pdf"}}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a53e4b07f02db62b578","contributors":{"authors":[{"text":"Flanigan, Vincent J.","contributorId":37735,"corporation":false,"usgs":true,"family":"Flanigan","given":"Vincent","email":"","middleInitial":"J.","affiliations":[],"preferred":false,"id":156208,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Sadek, Hamdy","contributorId":97491,"corporation":false,"usgs":true,"family":"Sadek","given":"Hamdy","affiliations":[],"preferred":false,"id":156210,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Smith, Bruce 0000-0002-1643-2997","orcid":"https://orcid.org/0000-0002-1643-2997","contributorId":43350,"corporation":false,"usgs":true,"family":"Smith","given":"Bruce","affiliations":[],"preferred":false,"id":156209,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Tippens, C.

Basin response to normal and extreme rainfall and snowmelt can be simulated to evaluate changes in water balance relationships, flow regimes, flood peaks and volumes, soil-water relationships, sediment yields, and groundwater recharge. Parameter-optimization and sensitivity analysis capabilites are provided to fit selected model parameters and evaluate their individual and joint effects on model output.

The analyses implemented an approach in which the control for sensitivity testing was a hypothetical aquifer representative of potential injection zones in south Florida, and parameter variations in sensitivity tests represented possible variations in aquifer conditions in the area. The permeability of the aquifer determined whether buoyancy stratification could reduce recovery efficiency. The range of permeability leading to buoyancy stratification became lower as resident fluid salinity increased. Thus, recovery efficiency was optimized by both low permeability and low resident fluid density. High levels of simulated hydrodynamic dispersion led to the lowest estimates of recovery efficiency. Advection by regional flow within the artesian injection zone could significantly affect recovery efficiency, depending upon the storage period, the volume injected, and site-specific hydraulic characteristics. Recovery efficiency was unrelated to the rate of injection or withdrawal or to the degree of penetration of permeable layers, and improved with successive cycles of injection and recovery.

Although a previous, airborne electromagnetic survey found no anomalies in the vicinity of the ancient mines in the region, surface indications of anomalous copper and zinc at both Dhahar and Al Hajrah are abundant. \r\n\r\nReconnaissance Crone electromagnetic traverses across the Dhahar prospect area delineated numerous conductive zones, but none had a dip-angle anomaly of more than 10?. Similar results were obtained at Al Hajrah. \r\n\r\nWith one or two encouraging exceptions, self-potential surveys at Al Hajrah showed only broad gradients and anomalies having amplitudes of less than 40 mV. Dipole-dipole induced polarization surveys at Al Hajrah delineated two nearly continuous polarizable zones having an aggregate strike length of almost 7 km. The two zones are symmetrically disposed on either side of a median aplitic dike and may lie on opposing limbs of a south-plunging antiform. Chargeabilities in the anomalous zones are weak to moderate but in most places are clearly associated with anomalous copper and (or) zinc concentrations found by surface sampling. \r\n\r\nGround electromagnetic traverses are recommended to determine the most conductive intervals of anomalous induced polarization effect in the anomalous zones; these conductive intervals should then be tested by drilling, where appropriate. Reconnaissance self-potential traverses are also recommended at Dhahar, and additional ground electromagnetic surveys are recommended across two airborne electromagnetic anomalies located immediately southeast of the Al Hajrah target.","language":"ENGLISH","publisher":"U.S. Geological Survey,","doi":"10.3133/ofr83778","usgsCitation":"Blank, H., 1983, Geophysical investigations in the Dhahar-Al Hajrah region, Wadi Malahah Quadrangle, southwestern Saudi Arabia: U.S. Geological Survey Open-File Report 83-778, ii, 31 p. :ill., maps ;28 cm., https://doi.org/10.3133/ofr83778.","productDescription":"ii, 31 p. :ill., maps ;28 cm.","costCenters":[],"links":[{"id":150539,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/of/1983/0778/report-thumb.jpg"},{"id":47548,"rank":400,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/of/1983/0778/plate-1.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":47549,"rank":401,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/of/1983/0778/plate-2.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":47550,"rank":402,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/of/1983/0778/plate-3.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":47551,"rank":403,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/of/1983/0778/plate-4.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":47552,"rank":404,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/of/1983/0778/plate-5.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":47553,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/1983/0778/report.pdf","linkFileType":{"id":1,"text":"pdf"}}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4ac8e4b07f02db67c1b6","contributors":{"authors":[{"text":"Blank, H.
