Hydraulic Characteristics and Water-Supply Potential of the May 1975 Aquifers in the Vicinity of the Wastewater Treatment Plant, South Bend, Indiana (open access)

Hydraulic Characteristics and Water-Supply Potential of the May 1975 Aquifers in the Vicinity of the Wastewater Treatment Plant, South Bend, Indiana

Abstract: An intensive study was made of a 24-square mile (62-square kilometer) area surrounding the South Bend wastewater treatment plant to document the effects of dewatering about 40 feet (12 meter) of the 130-feet (40-meter) thick aquifer during construction at the plant, define the hydrologic system in order to allow development of a predictive model and select and evaluate one possible water-supply development plan as a model demonstration. Model-simulated water levels agree very well with those observed, both before and during dewatering. Model results indicate that the hydrologic system can sustain withdrawal of 28 million gallons per day (106,300 cubic meter per day) indefinitely with little effect on ground-water levels. The quantity that would be diverted from the St. Joseph River is less than 10 percent of the estimated minimum daily flow.

Sediment Transport and Source Areas of Sediment and Runoff, Big Sandy River Basin, Wyoming (open access)

Sediment Transport and Source Areas of Sediment and Runoff, Big Sandy River Basin, Wyoming

Abstract: A study was conducted for the resolution of sediment source areas in the Big Sandy River basin, southwestern Wyoming. Suspended-sediment and bedload data were collected in order to determine total sediment transport at several locations within the basin. The bedload data were compared to the Einstein bedload function and total load data were compared to the Colby method. The bedload comparison showed a higher estimation of transport rates with Helley-Smith sampler measurements than with the Einstein beadload function. The Colby method yielded higher transport rates at high flows and lower transport rates at low flows than the measured total transport rate. The Big Sandy reservoir acts as a control in the basin. The area upstream of the reservoir was interpreted separately from the area downstream for source-area determination. In the arid plains upstream of the reservoir, the amount of sediment transported increased 98 percent with an increase in runoff of only 1 percent.

Experimental Study of Artificial Recharge Alternatives in Northwest Hillsborough County, Florida (open access)

Experimental Study of Artificial Recharge Alternatives in Northwest Hillsborough County, Florida

Abstract: Extensive water withdrawal from Floridian aquifer in the urban Tampa Bay area has induced leakage from the overlying surficial aquifer adversely effecting the water table and lake levels. Artificial recharge could reduce the impact of these adverse effects. Four experiments were conducted to investigate possible recharge alternatives; sinkhole recharge, water-spreading, connector wells, and subsurface-tile drainage to a deep well. Experiments indicate that all four methods can be effective. However, the sinkhole recharge experiment moved the greatest potential for draining the surficial aquifer. Combinations of the four methods could be used where potential exists for downward movement of water and sufficient unsaturated aquifer for water storage.

Availability of Ground Water near Carmel, Hamilton County, Indiana (open access)

Availability of Ground Water near Carmel, Hamilton County, Indiana

Abstract: Flow in the unconsolidated glacial deposits near the city of Carmel in central Indiana was simulated by a digital-computer model in a study of hydraulic characteristics of the deposits. The study shows that 21 • 3 million gallons per day (933 liters per second) of additional water could be withdrawn from the aquifer for an indefinite period of time. This pumpage is approximately 5 million gallons per day (219 liters per second) above the projected water needs of Carmel for 1990. Saturated thickness, transmissivity, and storage coefficient of the outwash aquifer along the White River east of Carmel were determined, using available data supplemented by test drilling . The saturated thickness of the aquifer ranges from 10 to 110 feet 0 to 34 meters ); transmissivity ranges from 1,000 feet squared per day (93 meters squared per day) to 24 ,000 feet squared per day (2 ,230 meters squared per day); and the average storage coefficient is 0.11.

Graphical Method for Estimating Occurence and Duration of a Critical Low Flow in the Sacramento River at Freeport, California (open access)

Graphical Method for Estimating Occurence and Duration of a Critical Low Flow in the Sacramento River at Freeport, California

Abstract: Sacramento County expected to begin operation of the Sacramento Regional Wastewater Treatment Plant in 1982. The California State Water Resources Control Board has ruled that the plant will not be allowed to release effluent into the Sacramento River when flow in the river is 4,000 cubic feet per second or less. Depending on tide condition, flows less than 4,000 cubic feet per second may occur either once or twice during each 24-hour 50-minute tide cycle when the daily mean flow is less than about 12,000 cubic feet per second. Daily mean flows less than 12,000 cubic feet per second occur about 28 percent of the time. Riverflow at the plant outfall is monitored by an acoustic streamflow measuring system. Regulation of effluent released from the plant will normally be based on real-time flow data computed by the acoustic system. A graphical method for determining the occurrence and duration of flows of 4,000 cubic feet per second and less was developed as a backup system to be used if a temporary failure in the acoustic system occurs.

Historic Water-Level Changes and Pumpage from the Principal Aquifers of the Memphis Area, Tennessee: 1886-1975 (open access)

Historic Water-Level Changes and Pumpage from the Principal Aquifers of the Memphis Area, Tennessee: 1886-1975

Abstract: Annual pumpage for both the Memphis Sand ("500-foot" sand) and Fort Pillow Sand ("1400-foot" sand) from the time of initial pumping from these aquifers to 1975 is presented in both tabular and graphic forms . The Memphis Sand supplied 188 million gallons per day in 1975 or 95 percent of the total water used in the area . Pumpage from the Fort Pillow Sand has decreased in recent years and in 1975 was about 4 million gallons per day. Pumping increases from the Memphis Sand have caused an almost continual decline of water levels as shown by graphs , tables, and a series of potentiometric-surface maps. Water-level-change maps show the fluctuations in water levels for two periods of high water use. Water levels in the Fort Pillow Sand are also shown by tables and graphs and a potentiometric-surface map . These graphs illustrate a rise of water levels since 1963, coincidental with pumping reductions. The data presented suggest that a constant pumping rate will cause little water-level decline and that the water levels can be altered for efficient resource management by areally varying the distribution of pumping . The references listed support the information presented in this report .

Effects of Ground-Water Development on the Proposed Palmetto Bend Dam and Reservoir in Southeast Texas (open access)

Effects of Ground-Water Development on the Proposed Palmetto Bend Dam and Reservoir in Southeast Texas

Abstract: Ground water continues to discharge into the Navidad and Lavaca Rivers by seepage out-flow even though large amounts of ground water are pumped for irrigation. Although a reduction in streamflow probably has occurred, a complete loss of the low flow of the streams by infiltration to a lowered water table seems remote. The large ground-water withdrawals will continue to cause land-surface subsidence, which will range from 0.012 foot to more than 0.026 foot per year. A minimum of about 0.013 to 0.015 foot of annual subsidence at the upper ends of the proposed reservoir and a maximum of about 0.019 foot near the dam site can be expected. Structural failures of manmade features have not occurred from the subsidence, but regional changes in the land slope have occurred and will continue . Numerous fault traces have been mapped in the area, but most of the faults are inactive. If movement along the fault planes should occur, the vertical displacement probably will not exceed the total subsidence.

Hydrology of the Albemarle-Pamlico Region, North Carolina -- a Preliminary Report on the Impact of Agricultural Developments

From abstract: Extensive agricultural land clearing and drainage operations underway in a 650 square mile part of the Albemarle-Pamlico region--a 1,634 square mile peninsula in North Carolina lying between Albemarle Sound on the North and the Pamlico River on the south--are changing the hydrology of the area. The artificial drainage system being constructed in the region, although it will probably result in only a slight modification of the natural annual evatranspiration, overland runoff, and ground-water discharge, will likely result in several important problems.
