Assessment Of Surface Water Runoff And Groundwater Recharge Using Mathematical Models, Khaled Omar Mohamed Haroon

Accounting Dissertations

In and semi-arid regions, surface water resources are scarce and, in most cases, groundwater is the onlynatural resource of freshwater. Pumping of groundwater often exceeds natural recharge. Therefore,groundwater level are declining and its quality is deteriorating. Sustainable management of groundwater is thus a key Issue and requires implementation of appropriate technologies to augment ground water resources. Artificial recharge augments the natural movement of surface water into the underground form' illations using some means of construction whereby surface water from streams or lakes is made to infiltrate into the ground.

A Concept Of Maximum Stream Depletion Rate For Leaky Aquifers In Alluvial Valleys, Vitaly A. Zlotnik

Department of Earth and Atmospheric Sciences: Faculty Publications

Existing analytical models for evaluating stream depletion by wells in alluvial aquifers are based on the assumption that stream depletion supplies 100% of groundwater withdrawals. Analysis of specific hydrostratigraphic conditions in leaky aquifers indicates that stream depletion may range from 0 to 100%. A new concept of maximum stream depletion rate (MSDR) is introduced and defined as a maximum fraction of the pumping rate contributed by the stream depletion. Several new analytical solutions indicate that the MSDR is determined by aquifer hydrostratigraphic conditions, geometry of recharge and discharge zones, and locations of pumping wells.

Geomorphic And Environmental Change Around A Large, Aging Reservoir: Lake C. W. Mcconaughy, Western Nebraska, Usa, R. Matthew Joeckel, Robert F. Diffendal Jr.

Robert F. Diffendal, Jr., Publications

Lake C. W. McConaughy, a 63-year-old manmade reservoir in the North Platte Valley of western Nebraska, is the largest standing body of water in the state. From the time that Kingsley Dam was completed in 1941 until the present day (2004), many geomorphic and environmental changes have occurred along the shores and within the North Platte Valley. Erosion on the southeastern shoreline of the lake had been perceived as a problem for landowners and managers for at least three decades, but the full scale of erosion was revealed only after a cumulative 18-m drawdown in lake level: bedrock platforms, extending …

Testing Density-Dependent Groundwater Models: Two-Dimensional Steady State Unstable Convection In Infinite, Finite And Inclined Porous Layers, Douglas Weatherill, Craig T. Simmons, Clifford I. Voss, Neville I. Robinson

United States Geological Survey: Staff Publications

This study proposes the use of several problems of unstable steady state convection with variable fluid density in a porous layer of infinite horizontal extent as two-dimensional (2-D) test cases for density-dependent groundwater flow and solute transport simulators. Unlike existing density-dependent model benchmarks, these problems have well-defined stability criteria that are determined analytically. These analytical stability indicators can be compared with numerical model results to test the ability of a code to accurately simulate buoyancy driven flow and diffusion. The basic analytical solution is for a horizontally infinite fluid-filled porous layer in which fluid density decreases with depth. The proposed …

Potential Contaminants At A Dredged Spoil Placement Site, Charles City County, Virginia, As Revealed By Sequential Extraction, Jianwu Tang, G. Richard Whittecar, Karen H. Johannesson, W. Lee Daniels

OES Faculty Publications

Backfills of dredged sediments onto a former sand and gravel mine site in Charles City County, VA may have the potential to contaminate local groundwater. To evaluate the mobility of trace elements and to identify the potential contaminants from the dredged sediments, a sequential extraction scheme was used to partition trace elements associated with the sediments from the local aquifer and the dredged sediments into five fractions: exchangeable, acidic, reducible, oxidizable, and residual phases. Sequential extractions indicate that, for most of the trace elements examined, the residual phases account for the largest proportion of the total concentrations, and their total …

The Effects Of The 2001-2002 Drought On Maine Surface Water Supplies, Catherine Schmitt

Electronic Theses and Dissertations

Maine lakes and streams serve as significant sources of public water supply, serving 40% of the population. Drought affects surface water resources by reducing water quantity and altering water quality, for example by reducing inputs of materials from the watershed and increasing water residence times. The 2001-2002 drought was the worst in Maine in over thirty years, and it exposed deficiencies in current water resources planning and management. In this study, I evaluated the effects of the 2001-2002 drought on Maine public water systems in order to identify characteristics of systems vulnerable to drought and determine appropriate indicators of drought …
