Wetland Designs for Environmental Protection?Application in India
In many developing countries raw sewage are discharged into rivers and lakes. This practice causes severe degradation of regional water quality, and often results in serious public health...
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;...
Direct Measurement of Turbulence Structures in a Standard Jar Test Tank Using PIV System
Particle image velocimetry (PIV) is applied to the measurement of instantaneous two-dimensional velocity fields in a standard 2-liter jar test tank for several different impeller speeds....
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,...
Vegetation-Induced Drag: An Experimental Study
Open-channel flow models through vegetative canopies require a quantitative measure of the ability of plants to absorb momentum by form drag, which is commonly characterized in terms of...
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...
On Silt Abrasion Erosion of Three Gorges Hydraulic Turbine in the Future
In this paper the basic parameters of Three Gorges hydraulic turbine have been reviewed and the operation characteristics of Three Gorges hydropower Station pointed out. Combined with...
The Influence of Peak-Regulation of the Three Gorges Power Plant on Navigation
The paper studies the unsteady flow resulted from peak-regulation by daily regulation at both Three Gorges and Gezhouba Power Plants and concludes that the river section between the dam...
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...
Designing Concrete Culverts to Resist Scour Damage
Concrete culverts have been used for over 100 years. In this period, the main design concern centered on structural and hydraulic adequacy of the culvert. Scour is a relatively recent...
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...
