Quality Control/Inspection�Upper Stillwater Dam
Roller compacted concrete construction, or RCC, is a relatively new method of constructing concrete dams and involves placing and spreading no-slump concrete in horizontal layers and compacting...

Shallow Foundation on Sand Underlain by Soft Clay with Geotextile Interface
One technique for improving the load-bearing capacity of shallow foundations on soft clay soil is to construct them over a compact granular fill laid over the clay layer. However, the...

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...

Effect of Air Gap on Platform Reliability
A simplified reliability study of the effect of lateral wave forces impacting the deck of a fixed platform is presented. The reliability of the deck legs, considered the primary resistance...

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...

Irrigation-Induced Contamination Problems
At the Kesterson National Wildlife Refuge in the San Joaquin Valley of California, severe fish and wildlife problems (waterfowl mortality, embryonic deformities, and reproductive failures)...

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....

An Operations Advisor for Regional Water Management
The application of artificial intelligence techniques was evaluated for implementation for water control structure operations at the South Florida Water Management District. After an analysis...

Design of the Oasis Advisory System
Once the decision was made to develop an advisory system for the operation of water control structures within the South Florida Water Management District, a schedule of activities leading...

Assessing WQ Impacts Using a Hydraulic Model
Engineering projects may cause water quality impacts in estuarine systems. It is important to assess those impacts during the planning phase of the project so that mitigation measures...

Sea Level Rise and Water Resources Management
Sea level rise due to greenhouse effect will create significant impacts on coastal water resources management. Possible future management strategies to offset salinity intrusion and to...

Modeling Hydrologic Components of the Upper St. Johns River Project
Off-line stormwater management areas and riverine marsh conservation areas are the major components of the Upper St. Johns River Project, Florida. Dimensions and operations of these components...

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...

Mass Transport Modeling of Pearl Harbor
The U.S. Navy is planning to implement the use of organotin antifouling paints into the fleet. Such paints are already in use by commercial vessels and private pleasure crafts. As part...
