An Isolated Wetland Used for Stormwater Treatment
A marsh used for stormwater management showed gradually increasing levels of pH, dissolved oxygen and conductivity in the flow path. The system was especially effective in removing suspended...
Innovative Wetlands in Urban Settings Using Dredged Material
As a result of its work in the waterways of the nation, the U. S. Army Corps of Engineers (USACE) has restored or constructed wetlands using dredged material in a number of urban/suburban...
Innovative Wetland Re-creation in Urban Setting
The project site is a 106 hectare, mixed-used, commercial development east of Tampa, Florida and at the westerly limit of the town of Brandon, Florida. Delaney Creek traverses the site...
Water Temperature Issues in the 90's and Beyond
Temperature impacts are among the most common and most expensive environmental issues requiring mitigation at water projects. Several emerging environmental and regulatory concerns and...
Sacramento and Trinity River Systems: A Demonstration of River Temperature Management for the 90's
Drought in Northern California resulted in the potential that summer and early fall, 1992, Sacramento and Trinity River temperatures would exceed critical levels for sustaining salmon...
Development of Bioretention Practices for Stormwater Management
This paper introduces the concept of bioretention as an innovative stormwater quality management practice. Bioretention is a method to treat the first flush of runoff using a combination...
Design Considerations Associated with Bioretention Practices
This paper presents the design requirements of bioretention practices. Bioretention is a stormwater management practice using a combination of retention, native terrestrial vegetation...
Pollutant Removal Efficiency of Detention Basins
A simple method is presented for quick estimates of pollutant removal efficiency of detention basins under dynamic conditions. The method is based on the generalized solutions to the reservoir...
Long-Term Performance of Wet Detention Ponds
Wet detention is a technology which has been successfully applied in recent years to improve stormwater runoff quality in urban areas. Since most systems have a short operational history,...
Managing Snake River Operations for Juvenile Salmon Migration
A simulation model of Snake River hydrology and water management institutions has been developed. The model was used to investigate management changes to enhance flow conditions for migrating...
Columbia River System Operations ? Water Quality Assessment
In mid-1990, the U.S. Army Corps of Engineers, U.S. Bureau of Reclamation, and Bonneville Power Administration embarked on a Columbia River system operation review. Ten technical work...
Snake Reservoir Drawdown ? A Brief Progress Report
The Northwest Power Planning Council has directed the region to employ the use of 'Drawdown' as tool to help threatened and endangered salmon stocks in Snake and Columbia rivers unless...
Water Quality Impacts from Development of Port Ludlow, Washington
Port Ludlow Bay is a tidal estuary located adjacent to Admiralty Inlet in Puget Sound, Washington. A planned development has been under construction along the bay since 1976. A 0.64 mgd...
Multiobjective Models for Determining Fresh Water Inflows to Bays and Estuaries
This paper presents two formulations of multiobjective models for the estuary management problem that are based on goal programming procedures. The multiobjectives are selected to be minimum...
City of Federal Way Panther Lake Surface Water Study?A Case Study of HSPF Modelling in Urban Detention Basins
This paper presents a case study of using Hydrologic Simulation Program-Fortran (HSPF) as a tool for sizing large urban detention facilities. The Panther Lake drainage basin is a textbook...
Water Quality Model of the Chicago Waterway
In 1992, the Metropolitan Water Reclamation District of Greater Chicago (the District) developed a QUAL2E water quality model of the Chicago waterway and Upper Illinois waterway. The model...
Simulation of Water Quality Processes in the Chicago Waterway and Upper Illinois River Systems
The U.S. Environmental Protection Agency QUAL2E-UNCAS (QUAL2EU) computer program was used to simulate the water quality processes in the Chicago waterway and Upper Illinois River Systems....
Optimization of Operations?The Manitoba Hydro Experience
As part of a decision support system, Manitoba Hydro implemented a comprehensive optimization model for operations planning in the mid 1980's (Barritt-Flatt and Cormie 1991). Since that...
Impacts of Hydropower Operation on Water Supply from Lower Colorado River in Texas
The Lower Colorado River Authority (LCRA) of Texas is both a water and energy supplier to a large area of Central Texas. LCRA generates approximately 10 percent of its power from hydroelectric...
Optimal Utilization of a Multi-Reservoir Water Distribution System
A water supply distribution system planning model (DSPM) has been developed using a linear programming approach. Unlike the conventional formulation, the water demand requirements are...
