Risk Analysis for Urban Stormwater Quality Management

Flood Quantiles for Small Watersheds Using Peak Elevation to Volume Method

Two-dimensional Sheetflow Modeling for Wetland Restoration
The hydrologic-hydraulic behavior of wetlands and transitional upland-wetland areas on coastal flat terrains in the Cocohatchee Canal Watershed in Collier County, Florida was simulated...

Effect of Grade Control Structures on DEC Streams
Controlling the grade of a channel with structures has been an effective means applied to streams. Although, the effectiveness of grade control structures is not readily apparent until...

Santa Clara River Fluvial Analysis
The Santa Clara River watershed, located in Los Angeles County, has been subject to rapid increases in population and urban development, resulting in channelization, new bridges, and increased...

Simulating Evapotranspiration on Semi-Arid Rangelands
Detailed simulations of the surface energy balance using the Simultaneous Heat and Water (SHAW) model were compared with measurements collected at the Reynolds Creek Experimental Watershed...

Watershed Management for a Limited Coastal Aquifer System
Developing a watershed strategy, which incorporates key issues of a particular watershed, may entail the coordination of several different agencies. Work performed by the USGS, local public...

Selecting Design Conditions as Part of a Watershed Approach to Water Quality Control
EPA water quality guidance recommends that water quality criteria be exceeded no more than once in three years. Standard approaches, based on the use of critical design conditions, have...

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...

Watershed Characteristics and Hydrological Parameters vs. Sediment Yield—Northern Regions of Pakistan
In order to manage, restore, or effectively maintain a watershed it is necessary to know what is really going on inside that watershed, which includes the effects of watershed and hydrological...

Modeling the Lake Decatur Watershed in Illinois to Evaluate Effects of Best Management Practices on Nitrate Loading
The Illinois State Water Survey recently completed a two-year monitoring and modeling study of the Lake Decatur watershed in Illinois to develop land use management alternatives that would...

Stormwater Management Plan Updated for Climate System Changes
When large watershed stormwater management plans are updated, climate system change factors due to global warming effects should be considered. Climate system changes may cause changes...

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,...

The Treatment Train Detention Concept
With the recent concern for nonpoint source pollution impacts to receiving waters, the Village of Saukville, Wisconsin took advantage of state funding grants to conduct a Stormwater Management...

Water Quality Modeling of the Rouge River Watershed
A relatively detailed modeling framework for calculating pollution flows and loads to the Rouge River has been developed and tested successfully. The framework includes consideration of...

Interdisciplinary Research of Mountainous Areas: Past, Present, and Future
In the past few years, there has been a growing recognition internationally, of a need to better understand hydrometeorologic, hydraulic, sedimentologic, geomorphic processes in gravel-,...

A DEM Based Hydrologic and Sediment Transport Model
A DEM-based, physically-distributed model was developed for simulating event runoff and erosion on an agricultural watershed. Runoff was described using the diffusion equation with flow...

Effects of Spatial Data Resolution and Subarea Size on a Distributed Runoff Model
Spatial data layers of elevation, land use, and soils for a small agricultural watershed in Pennsylvania were used to study the effect of resolution degradation of raster data on the output...

The Sawmill Creek Watershed Restoration Project
The Sawmill Creek project is a comprehensive watershed restoration effort. The goal is to demonstrate that existing programs can be coordinated in order to improve water quality, and habitat...
