Privatization and Water Supply/Treatment Projects
Privatization is often mentioned as a way to get much needed, but difficult to finance infrastructure projects delivered for both developed and developing countries. However, the suitability...
Managing Conflicting Demands from Endangered Species: Taking the Challenge
Reservoir system managers face conflicting demands from interests such as water supply, flood control, recreation, hydropower, and environmental preservation. Historically, water resource...
Consensus as the Measure of Sustainability
Sustainable development is the Holy Grail of the `90s. Yet, its practical implications seem to be elusive. Metrics for measuring the level of sustainability are eagerly sought. It is very...
Laboratory Evaluation of a Conductivity Probe for Scour Monitoring
Laboratory tests were used to evaluate the ability of conductivity sensors to measure streambed elevation. Tests were completed on a 2.1-m probe with a resolution of about 8 cm that was...
Evaluation of Selected Instruments for Monitoring Scour at Bridges in New York
Reliable methods to monitor scour at bridges are needed to ensure public safety and minimize the cost to repair or replace vulnerable bridges. The U.S. Geological Survey, in cooperation...
Design of Guide Banks for Bridge Abutment Protection
As an alternate to designing bridge abutments to withstand the development of the full scour prism predicted by equations currently available for estimating abutment scour, FHWA recommends...
Restoration Design for Urban Streams: Anacostia River Basin, Maryland
Several stream restoration projects have been undertaken by the Army Corps of Engineers in the Maryland portion of the Anacostia River basin. Measures used include bank stabilization,...
Retrofitting an Urban Watershed for Improved Water Quality
A study was conducted for the Baltimore County, Maryland, Department of Enviromnental Protection, to assess the watershed conditions and stream channel stability of Stemmer's...
Lake/Reservoir Restoration Activities in Taiwan
The paper presents a brief overview of recent lake and reservoir restoration project activities in Taiwan, an island nation in a sub-tropical and relatively wet climate. Because of steep...
An Engineering Information System Application for Water Supply and Distribution Systems
Engineering information systems are characterized by both static infrastructure and dynamic time dependent data. Telemetered readings can often be relatively substantial over an extended...
Effect of Reservoir Hedging on Crop Yield Under Deficit Irrigation Conditions
In case of irrigation projects, irrigation scheduling at the field has a direct bearing on yield crops. Hence, the various reservoir operating policies considered have to be evaluated...
Commercial Wetland Mitigation Banking
Wetland mitigation banking, although practiced for more than fifteen years, is a concept just beginning to be widely embraced and implemented as an important wetlands regulatory and management...
Washington State's Stormwater Management Program
Significant progress has been made in developing a stormwater management program at the Washington State Department of Transportation (WSDOT). Topics highlighted in this paper include:...
Salinity Management for the Upper Gila River
Over development and over allocation of the limited water supply of the S afford valley in eastern Arizona has resulted in serious depletion of water for irrigation in the San Carlos Apache...
Derivation of New Dispersion Coefficient Equation for Natural Streams
A new simple method for predicting dispersion coefficient by using hydraulic and geometric data easily obtained in natural streams has been developed. Dimensional analysis was implemented...
Pollution Transport in Karst
A new model of pollution transport in natural streams was developed and tested. Dead zone storage is modeled as a two time constant process. This approach better matches the observed persistence...
Utilizing Coordinated Billing and Metering Systems Analysis to Enhance Utility Revenue on a Shared Revenue Basis
The Jefferson Parish Water Department provides water service to over 450,000 residents through 132,000 active utility connections and provides billing services for all Parish operated...

The Costs and Benefits of Dam Removal on the Elwha River
The Elwha River is located on the Olympic Peninsula in the State of Washington. In the early 1900s two hydroelectric dams were built on the Elwha River. Construction of Glines Canyon and...
Use of ??8O and ?D to Define Seawater Intrusion
On the basis of previous studies, more than 60 km? of upper aquifer system underlying the Oxnard Plain was believed to be intruded by seawater. Recent work has shown that there are sources...
