Water Resources Investigation Along Salt River in Phoenix and Tempe Area
The Salt River originates in the White Mountains of eastern Arizona and drains westward through the Phoenix metropolitan area to its confluence with the Gila River approximately 15 miles...
Suspended Sediment Loads in Dry and Wet Years
Many factors other than water discharge influence the suspended sediment load in rivers. The climate condition is one of the factors. It is expected that the relation between Qs...
Specification of Cu, Pb and Cr in Contaminated Sediment Effected by pH
Sediment was sampled from a contaminated river. Sequential extraction was applied to determine the speciations of Cu, Pb, and Cr in the sediment with varied pH (5?9), and the redox potential...
Use of Channel Forming Discharge Concepts for Flood Control Channel Design
Evidence suggests that for perennial and ephemeral rivers that are in regime, bankfull flow is strongly correlated with channel morphology. Evidence suggests that this discharge is also...
The Integration of Receiving Water Impacts in the Evaluation Process of Alternative Designs for CSO Abatement in Providence, RI
The Providence, Rhode Island sewer system is undergoing a combined sewer overflow abatement program. One measure of the program's effectiveness is the reduction of water quality...
Operational Aspects of Warning
Uzbekistan is referred to as the region where the most dangerous natural phenomena are: mudfloods, floods, and avalanches. During the last decades the areas of their manifestation were...
A Paradox at the Rocky Mountain Arsenal, Colorado: Benefits of Applied Research
The Rocky Mountain Arsenal (RMA), which is located north of Denver, Colorado, was a manufacturing site for chemical weapons during World War II and pesticides for several decades after...
Effect of Surface Water and Ground Water Interaction on Atrazine Transport to Pumping Wells
High concentrations of agricultural chemicals in flood waters have been reported in many Midwestern rivers and streams. The public water supply wells of a number of riparian communities...
Pollutant Transport Across Porous Stream Beds
The presence of porous streambeds generates a significant interaction between the main stream flow above it and the flow through the porous sub-stratum. This coupling affects both flows,...
Application of Regime Theory in Practice: A Case Study
Alluvial channels are known to adjust their slope, width, depth and velocity to achieve stable conditions given a supply of water and sediment. Scientific investigations of stable channels...
Identifying Trends from Streamflow Records?A Case Study
Historical streaniflow records for the Ruby River, in southwestern Montana were analyzed for trends and for changes in the precipitation-runoff relationship. Trends were first identified...
The Last Two Extreme Floods in Germany?Analyses and Consequences
The last two extreme floods in Germany occurred in December 1993/January 1994 and January 1995 within the River Rhine basin with both floods having different causes. In a comparison study,...
Impact of Anthropogenic Activities in Rivers Upon Accuracy of Hydrological Forecasts and on Development of Forecasting Methodologies?Experiences from the Slovak-Hungarian Reach of Danube
The Danube, as an international river, crosses eight states of Europe. This calls for the need of close cooperation of the Danubian countries, particularly for operational forecasts issuance,...
Quantitative Monitoring of Plata River Basin Waters
The governments of Argentina, Bolivia. Brazil, Paraguay, and Uruguay, represented in the First Extraordinary Meeting of Chancellors of the Nations bordering the Plata River Basin, held...
Design and Construction of the Santa Ana River Wash Crossing of the Inland Feeder
The Inland Feeder Pipeline passes beneath the Santa Ana River in Southern California. The flood plain of the river provides the habitat for two endangered species and to avoid surface...
California Border Environment Activities Since Passage of NAFTA
This paper presents a summary of the activities undertaken by the State of California to improve the border environment since passage of the North American Free Trade Agreement (NAFTA)...
Modeling Climate Change Impacts on Water Resources
As part of the Electric Power Research Institute's (EPRI) comprehensive evaluation of the economic effects of climate change in the United States, we have developed methods...
Reduction of Downstream Impacts Through Use of Variable Detention Basin Volume Requirements
The Pre-post Match is the standard policy for regulating the design of detention basins for new developments despite evidence showing that as multiple developments occur in a watershed,...
Floodplain Analysis of the Lower Santa Margarita River in Camp Pendleton Marine Air Base, California
