Juvenile Fish Separator Design
Separation by size of downstream migrant juvenile salmonids at hydroelectric projects in the Columbia River basin is an integral part of transportation and bypass programs. However, separation...
Estimation of the Probable Maximum Rainfall and Snowmelt Floods Via Physically Based Model of River Runoff Generation
Disastrous floods can be caused by unusual combinations of hydrometeorological factors and river basin conditions that have not been observed during a long observation period. The physically-based...
Debris Basin Design Procedures
Debris basins are widely used in the southwestern areas of the United States, with the majority of the structures located in the Southern California area. More and more development is...
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,...

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,...
Flood Control in the Brazilian Electric System Reservoirs at Parana River Basin
This paper describes the experience of the Brazilian Electric System in flood control at Parana River basin, and presents the factors that required the consideration of flood impacts in...
A Stormwater Management Plan
Part 2 of the National Pollutant Discharge Elimination System (NPDES) Stormwater Permit requires both sampling and analysis of stormwater and the control of illicit discharges to stormwater...
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...
Searching for Optimal Combinations of Stormwater Detention Basins
Hydrology of urban areas is dominated by two distinct characteristics: (1) a preponderance of impervious surfaces created primarily by pavement and roofs, and (2) the presence of constructed...
Effective Subsurface Retention/Detention Systems
Stringent environmental regulations and increasing land values have made finding an effective way to manage storm water runoff a high priority for consulting engineers and land developers....
Cooperative Approaches in Achieving Additional Water Conservation at Prado Dam
The Orange County Water District (OCWD) has successfully negotiated multi party agreements that provide for the use of Prado Basin for water conservation while ensuring protection of the...
Identification of a General Linear Model for Reservoir Inflows Forecasting
General linear stochastic models represent a valuable alternative to conceptual models in order to describe runoff generating mechanisms in a drainage basin. In regions such as Quebec,...
The Part of Precipitation in Some Ecological Problems of the Dnister Basin
The purpose of the present paper is to study the peculiarity of precipitation falling in the Dnister basin, their distribution on territory, and research of several year's precipitation...
Flash Floods and Their Control in the Indian Arid Zone
Flash floods are common hydrologic phenomena in the arid north west India. Drainage basins of high relief, a large percentage of surficial bed rock, sparse vegetation, and shallow soils...
Are Erosion Control Programs Reducing Sedimentation?
In the Midwest, the USEPA National Watershed Monitoring Program is determining the effectiveness of land management strategies to improve water quality and biological diversity. The illinois...
Development of Islandwide Groundwater Pollution Potential for Taiwan
Using the modified DRASTIC and existing and newly surveyed data, groundwater pollution potentials for all 10 groundwater basins in Taiwan were calculated on 2 km by 2 km grids. This paper...
Development of a Hydrologic Model with Both Spatially Distributed and Physically Based Capabilities
