Third Party Impacts of Proposed Water Banking in the Colorado River Basin
Colorado River water is allocated to the seven Basin states based on a set of legal entitlements. Little flexibility is explicitly granted for addressing water shortages to particular...
Design Modification of Water Supply Intakes in Mountainous Regions
Existing river intakes for several water treatment plants in the mountainous areas of western Venezuela have experienced severe difficulties with deposition of sediment. Excessive sediment...
Stochastic Determination of Wave Heights for Flood Control Channels
Physical model data for subcritical and supercritical flow has been collected and analyzed to determine a statistically-based relationship for wave runup heights in a trapezoidal channel....
Application of a Three-Dimensional Model to Assess Seawater Intrusion in the South San Diego Embayment
The San Diego Formation is a Pliocene through Quaternary age aquifer occupying the southwestern-most part of San Diego County. Though the formation is widespread, thicknesses of up to...
Strategies for Operation of Orange County Water District Talbert Seawater Intrusion Barrier, California
Heavy groundwater production in the area of coastal Orange County accounts for large seasonal fluctuations in water levels that can cause groundwater gradients to reverse seasonally. The...
Transport Modeling of the Coastal Waters of Oahu, Hawaii
A hydrodynamic model of the coastal waters around the island of Oahu, Hawaii has been constructed to provide quantitative information on the movements and mixing of water that are to be...
The Fate of Pathogenic Organisms in Mamala Bay
The fate of enteric organisms in Mamala Bay is studied using coupled hydrodynamic and pathogen fate models. The purpose of the study is to determine the contributions of various sources...
The Mamala Bay Study, Oahu, Hawaii: Introduction
A comprehensive multi-disciplinary study was conducted to evaluate the effects of point and non-point source discharges on the water quality of Mamala Bay, Oahu, Hawaii. The investigation...
Comprehensive Modelling of Water Distribution Networks
An analyst of a water distribution systems must frequently contend with a host of problems with very different time scales. Traditionally, such concerns have been accommodated by having...
Moving from a Model to a Decision Support System: Salt River Project's Experience with a Reservoir Simulation System
The Salt River Project (SRP) is in the third year of a process to develop a computerized hydra-meteorological decision support system (Hydromet) that will eventually cover all aspects...
Integrated Facility Information Systems: Total Information Access
This paper will attempt to fill the void in computer information handling with regards to facility management information by providing those in the water industry with tips and suggestions...
A Knowledge Based System for the Design of Open Channels
The design of open channel facilities often calls for evaluation of a unique set of physical conditions which do not lend themselves to standard designs and textbook solutions. Consequently,...
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...
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...
