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...
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....
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...
Reliability Curves for Reservoir Performance
Seattle District, U.S. Army Corps of Engineers, has developed a family of reservoir guide curves that illustrate reliabilities when storage conditions gradually decline from 98% to as...
Geographic Information System Application: Water Right Places of Use as Polygon Attributes
A Geographic Information System (GIS) was tested for potential use as a water resource management tool by application to a ground water study area. Because of the limitations of the particular...
GIS Reconstruction of Exposure to Water Supply Contaminants
Groundwater pollution resulting from improper waste handling practices in the aerospace industry contaminated the water supply in Tucson, Arizona. State and federal health officials concluded...
Stochastic Forecasts in Reservoir Planning and Operations
The factors involved in stochastic forecasts of water supply and demand are discussed in relationship to reservoir planning and operating decisions....
Characterization of Uncertainty in Reservoir Operations
The development of operating policies for complex reservoir systems typically requires a consideration of various system component interrelationships and several conflicting operating...
Hydrologic Forecasting?What are the Issues?
The paper briefly describes hydrologic forecasting techniques that are being used today and raises issues that should be addressed as new hydrologic forecast systems are developed and...
The Development and Use of Policy Statements in River Simulation Models
There are a number of ways in which the physical operation of a river system can be expressed in simulation models. Most of the earlier simulation models have incorporated the operating...
Advanced Decision Support Systems for Environmental Simulation Modeling
Some new computer approaches for integrating simulation models into water-quality management and planning are described. A system for integrating models, databases and decision-support...
