The Use of an Equivalent Porosity Method to Model Flow in Marshes
Two dimensional modeling of marshes under unsteady flow conditions often involves description of sections that alternately wet and dry. The equivalent porosity method (King and Roig, 1988;...
Two- and Three-Dimensional Hydrodynamic Modeling of the Salton Sea, California
The Salton Sea, the largest surface water body in California, faces a myriad of problems related to rapidly changing water levels, rising salinity, accelerated eutrophication, fish kills,...
Data Analysis for Computer Modeling of Thermal Discharges
Assessment of the thermal discharge impact upon the environment and design of the appropriate discharge structure necessitate a range of data activities, from extensive field measurements,...
The Three Gorges Project: Relocation of Reservoir Population
The Three Gorges Project of China, the world.s largest single water resources project, was officially begun its construction in December 1994. The project involves a massive reservoir...
Capillary Pressure-Saturation Relationships in Fracture
Understanding and quantifying unsaturated flow through fractures in rocky slope is important for design and construction of drainage system in large-scale hydraulic engineering. The data...
Observations of Tidal Circulation in Mamala Bay, Hawaii
A comprehensive measurement program, designed to study circulation processes and support hydrodynamic modeling, has been carried out in Mamala Bay on the south coast of the Island of Oahu,...
Comparison of Near-Field Dilutions Derived from In Situ Measurements and Simulated Dilutions at the Sand Island Sewage Outfall Plume, HI
Near-field dilutions of the Sand Island Treatment Plant (SITP) wastewater plume were derived from salinity measurements made at the sewage outfall between Sept. 25?Oct. 1, 1994, a period...
Groundwater Recharge with Reclaimed Water Another Step Closer to Potable Reuse
California.s water supply is becoming increasingly unreliable, and investments to make water more reliable must be seriously investigated. In this arid region of Southern California, reclaimed...
Water and Sanitation Intervention in Flood Mitigation Programs
Disasters, like floods and cyclones, are almost annual events in Bangladesh. Often post-disaster epidemics of diarrhoeal diseases cause more short- and long-term health problems than injuries...
Flood Risk Management: New Concepts for an Objective Negotiation
It has been tested in a real situation like the Bourbre catch ment, a Rhone tributary in the Isere department, not far from Lyon (France). This catchment is 700 km large, the river is...
Scour at Culvert Outlets: Considerations Present and Future
One of the major considerations in the design and rehabilitation of the national transportation system is the conveyance of tributary drainage through constructed embankments. As drainage...
The Use of Hydrologic Budget Techniques in Assessing Site Suitability for Wetland Creation
This paper discusses the general concepts and benefits of using of hydrologic budget techniques to describe the typical hydrologic conditions that might be expected at prospective site...
Water Based Land Use Regulations Using GIS Water Budgeting Model
Protection of water quality and supplies in developing watersheds requires maintenance of the natural water budget. Water budgeting model using GIS provides foundation for land use regulatory...
Sustainable Watershed Management in Developing Watersheds
In many parts of the country, land development at the fringe of major metropolitan areas has accelerated and is occurring in historically unprecedented land consuming patterns. This development...
Implementation of Watershed Planning in Chester County Pennsylvania
The author presents portions of a study into the current watershed regulatory framework in Pennsylvania, and how effectively this framework supports watershed sustainability when faced...
A Decision Making Approach for Stormwater Management Measures?A Case Example in the City of Waukesha, Wisconsin
An urban nonpoint source pollution predictive model (Source Load and Management Model?SLAMM; Wisconsin Department of Natural Resources, 1990), and a decision matrix developed specifically...
Los Angeles River as a Water Source for a Freshwater Reservoir
Simons, Li & Associates, Inc., performed a study to examine the technical feasibility of a freshwater reservoir in the ocean at the mouth of the Los Angeles River through a conceptual...
Los Angeles County Department of Public Works Storm Water Quality Assessments, Los Angeles, California
This study included a general assessment of the surface water quality conditions within the Los Angeles County area by examination of the surface water quality data collected by LACDPW...
Modeling Combined Stresses on Aquatic Ecosystems
A mechanistic ecosystem response model is being developed by incorporating exposure/response relationships for selected natural and anthropogenic stresses into an existing hydrodynamic...
Effect of Pump-Ins on California Aqueduct Water Quality
A model has been developed, based on the assumption of constant Aqueduct volume, to predict the effect of ground water pump-ins on Aqueduct water quality. Designated SuperCAMP (California...
