Evaluation of Reservoir Seepage in Karst Topography
Areas where seepage is likely to occur in the karst environment of the proposed West County Reservoir, Roanoke County, Virginia have been indentified. Solutioning exists in the form of...
Regulatory and Environmental Issues of the Chisman Creek Superfund Site
This paper discusses the regulatory and environmental issues arising from the response to the Record of Decision (ROD) for the Chisman Creek Superfund Site in York County, Virginia. Field...
First-Order Reliability Analysis of Groundwater Flow
A method for stochastic analysis of groundwater flow based on the first-order reliability approach is presented. The method is well suited for problems in which statistical information...
Expert Systems for Drought Management: A Case Study
This paper describes the development and application of a computer model used by the Seattle Water Department (SWD) for operations during drought. This model provides guidance for initiating...
Extent of Water Quality Effects of Dams?A National Viewpoint
An overview of phosphorus impacts on impoundments, a subset of the contents of the Dam Water Quality Report is presented. The U.S. Environmental Protection Agency (EPA) is the lead investigator...
A Simple Nonpoint Source Groundwater Quality Management Model
A model is examined which efficiently produces information required by decision makers to assess water quality tradeoffs associated with alternative groundwater protection strategies,...
Tidewater Virginia's Water Supply Problem: Implications for State Water Management
Attempts to expand water supply in response to continuing urban growth in Virginia's Tidewater region has produced prolonged conflict among the area's local governments...
Regional Water Cooperation: An Alternative to Interbasin Transfer
Due to political and environmental impacts interbasin transfer is often regarded as an undesirable alternative for water supply development. However, water authorities will pursue interbasin...
Conflict Over Urban Water: An Economic Perspective
Water conflicts in the East are associated primarily with infrequent proposals by public water systems to move water across political boundaries. Also, most conflicts arise among political...
Socio-Economic Issues in Financing Water Resources Development Compared to Non-Structural Alternatives
Like the hydrologic cycle, financing water resources development requires a holistic view of the technical, legal, institutional (social and economic) factors before alternative selection....
Modeling Water Supply Benefits of a Shallow Lake in a River Reach
Minimum flow and level requirements based on ecological, water quality, recreation and other needs are established and used as limiting criteria in the development of a riverine lake as...
Water Quality Assessment and Management System in Regulatory Environments
State water quality regulatory agencies need to prioritize water bodies for program actions so that agency workload can be determined and resources allocated in order to achieve positive...
Spreadsheet Applications in Water Quality Management
The state regulatory environment requires simple, quick, easy to use and maintain water quality analysis tools. Therefore, for the evaluation of toxic substances, a new approach towards...
Reservoir Safe Yield Evaluation Using Simulation
The safe yield available from surface water impoundments serving the City of Portsmouth, Virginia, was evaluated, and the sensitivity of the reservoir system to several factors was investigated....
Risk Consideration in Water Supply Reservoir Capacity Design
This study develops a method for estimating the risk in reservoir capacity design by applying frequency analysis to the mass curve method. It provides a means for the engineer to use familiar...
Risk Management for Water Supplies During Droughts
This paper describes a method for deriving policies for the operation of public water supplies under impending and actual drought conditions. Unlike previous models based on optimization...
Determining Impacts of Sediment Using Cesium-137
Tecumseh Lake, in east-central Oklahoma, completed about 1934, has been identified by the Oklahoma Water Resource Board as a water supply critical to future development of the state. Aerial...
Stochastic Model for the Management of a Stream-Aquifer System
The management of a system of groundwater and surface water requires that the hydraulic connection of the two sources be investigated. The inherent uncertainties that exist in the data,...
Conjunctive Use Study of Groundwater and Surface Water in Chino Basin, California
The purpose of this paper is to study the effects of artificial recharge on an already contaminated unconfined aquifer and propose optimal recharging and pumping schemes to prevent the...
