Eddy Pump Dredging Demonstration at Cresta Reservoir
A demonstration test of a new environmentally ifiendly slurry dredging technology using the EDDY Pump, a patented vortex slurry pump, was perfbrmed in 1994 at Cresta Reservoir in northern...
Sediment Impacts on Yield from a Two-Reservoir System in Puerto Rico
The Dos Bocas and Caonillas reservoirs in Puerto Rico are being considered for conversion from hydroelectric to water supply operation. Both reservoirs are approximately 50 years old and...
Impacts of Reservoir Sedimentation on Decommissioning of Dams
A large number of dams in the United States of America and elsewhere are reaching the limits of their design lives. Owners, agencies and environmentalists are either considering or demanding...
US/Mexico Border Drinking Water Study
This report is an outgrowth of a more detailed report, written as part of an Environmental Protection Agency (EPA) study. This report represents my views, and does not necessarily represent...
Emerging Concepts for Management of Salinity and Drainage in Irrigated Regions
The purpose of this paper is to very briefly highlight some physical and design concepts important to management of salinity and drainage in irrigated regions in an environmentally sensitive...
Shallow Ground Water Management with a Modified Subsurface Drainage System
An existing subsurface drainage system was modified to control the flow from the drain laterals and to control the water table depth on a portion of the field. Tomatoes and cotton have...
Efficiencies of Drainage Systems and Improved Water Management
Drainage of agricultural lands has become a contentious issue as concern increases over the actual economic benefits of subsurface drainage in irrigated regions relative to the impacts...
Vulnerability of Water Resources to Global Climate Change in the Agricultural Midwest- Ecological, Economic, and Regulatory Aspects
As climate changes, so will water resources. General climate change will alter the distribution of hydrometeorological events and will affect water use, in turn resulting in further alterations...
Forcing Function and Climate Change
A system framework for investigating the effect of climate change in the upper Rio-Grande river basin, New Mexico, is developed. The forcing function or input into a climate change model...
Integrated Hydrological/Ecological/Economic Modeling for Examining the Vulnerability of Water Resources to Climate Change
A methodology for assessing regional-scale hydrologic vulnerability to climate variability which incorporates ecologic and economic factors is presented. A simple economic model of damages...
Adapting Water Resources of the Canadian Prairies under the impact of Climatic Warming
Given that future droughts could become more frequent and more severe because of climatic warming, this paper discusses some strategies to manage and to develop the water resources of...
Beneficial Aspects of Flood and Rain in Countries Where the Drinking Water is Naturally Contaminated with Fluoride Where Fluorosis is a Major Public Health Problem
Floods, although considered destructive, have beneficial aspects too. This report is about one such instance where flood waters are considered extremely beneficial in countries where drinking...
Aspects of River House Cleaning during Floods
In spite of all the destructive forces of floods, the washing and scouring of polluted bottom deposits during spring floods gives the rivers a new start at the beginning of what is usually...
Pier Scour at Wide Piers
Scour at relatively wide piers in shallow water is not explicitly accounted for in the current HEC-18 scour equation. The scour estimated for this case is often overpredicted. In this...
Effects of Ignoring Well Losses on the Specific Capacity Function
This paper combines these equations with the traditional step-drawdown equation to generate a more realistic relationship among discharge, specific capacity, and drawdown. Under both confined...
Delineating Subsurface Contamination Using Geostatistical and Non-Intrusive Geophysical Methodologies
Electromagnetic (EM) conductivity surveys are becoming a more practiced technique in screening for contamination of soil and groundwater. This non-intrusive geophysical approach detects...
PCE in Dewatering Flows?A Case Study Risk-Based Clean-Up Action Levels
Up to 70 micrograms per liter (?g/L) of tetrachloroethylene (PCE) was detected in dewatering flows associated with a construction project (Project) in the City of Los Angeles. Because...
Technical Activities in a Large Branch or Section
The Texas Section of the American Society of Civil Engineers (ASCE) is currently one of the largest Sections in the Society. Similarly, the Houston Branch is one of the two largest Branches...
Organizing a Local Water Resources Technical Group
Participating in a local water resource technical group can be rewarding professionally as well as socially. However, if such a group does not exist in your area, organizing one is an...
The Birth and Success of Orange County's Hydrology and Hydraulics Technical Group
The Orange County.s Hydrology and Hydraulics Technical Group (HHTG) has been very successful ever since it was founded in 1991. The HHTG is incorporated as a Technical Group under the...
