Calibration and Validation of the Storm Water Management Model to the Providence Area Combined Sewer System
This paper exemplifies the calibration and validation of the EPA Storm Water Management Model (SWMM) to one drainage area within the Providence (RI) area combined sewer overflow system....

Management of Portland's Combined Sewer System
The City of Portland, Oregon, has embarked upon a two-year program to develop a long-term management program for its combined sewer system. A team of consultants is assisting the City...

A Multi-objective Criteria Analysis for Alternative Route Planning
A multi-objective criteria analysis was used to identify a proposed rail spur route with the optimal combination of low environmental impact, favorable engineering characteristics and...

Information Theory and Multi-Objective Evaluation
The evaluation of alternatives with scarce knowledge is a common decision-making situation. This situation contrasts with decision-making in the presence of abundant knowledge, which is...

Ongoing Monitoring Results Pilot Stormwater Disposal Facilities, Pierce County, Washington
The three stormwater disposal facilities evaluated appeared to increase in pollutant removal effectiveness after approximately 4 to 5 months of operation. This may be due to the deposition...

Dry Weather Field Screening as an Indicator for Urban Drainage System Rehabilitation
In November 1990, EPA published final rules governing National Pollution Discharge Elimination System (NPDES) Permit Application Regulations for stormwater discharges. The rules affect...

Coupled Water-Wastewater Management Issues
The concept of coupled alternatives is an emerging engineering issue in master planning for water resources management. Coupled alternatives involve the concurrent evaluation of water...

Winter Nutrient Losses to Groundwater Associated with Various Tillage Manure Systems
Excessive nutrient leaching to groundwater in agricultural watersheds has initiated research to develop control systems. Loading of nutrients are enhanced during the non-growing season...

Building a Pipeline?Not a Flow Through Process
This paper will illustrate that the planning, design, and construction of a 32-mile water supply pipeline from Stockton Lake to Springfield involves more than just digging a trench, placing...

Modeling of a Large-Scale Water Distribution System
Metropolitan Water District of Southern California (MWD) imports water from the California State Water Project and the Colorado River, providing for supplemental water demands for six...

Environmental Management Issues in Developing Countries of Southeast Asia
Acknowledging the escalating concerns regarding the environmental impact of water resource projects, a serious effort must be made to identify and review environmental issues which directly...

The Total System Solution
Most pipeline reconstruction programs carried out to date have been crisis driven or reactive instead of system wide approaches to problem solving. Two tools have been devised to change...

CSO Rehabilitation Strategies for Urban Areas
The USEPA national strategy for reduction of combined sewer overflows places high priority on maximizing the amount of combined wastewater that is captured and treated in the existing...

Managing Existing Reservoirs to Meet New Challenges
The current planning and management environment for many reservoirs differs significantly from the situation which existed when the projects were initially planned and constructed. Yet,...

Urban Infrastructure: Our Crumbling POTW's
There is a need to address the problem of deferred maintenance at public owned treatment works. While specific data regarding the nations deferred maintenance bill is not available, we...

The Challenge of Kissimmee River Restoration
Between 1962 and 1971, the Kissimmee River in central Florida was channelized by the Corps of Engineers as part of a flood control project. Channelization has resulted in degradation of...

Funding of Wastewater Reuse Systems Under the Federal Small Reclamation Projects Act
The Small Reclamation Projects Act (SRPA) and its amendments were enacted to encourage State and local participation with the Federal government in water resources development. A key element...

Usefulness of Low-Cost Watershed Monitoring: A Case Study
A one-year monitoring study was conducted for Harford County, Maryland to identify water quality problems and sources in the 98 mi² Bush River watershed....

Delaware Estuary Nonpoint Source Control Program
Preparation of the Delaware Estuary Management Plan, sponsored by the EPA and the three states of New Jersey, Pennsylvania and Delaware, is part of the national estuaries program. As part...

Water Management as an Instrument for Cooperation and Reconciliation
Empirical models for identifying potential water quantity and water quality conflicts in water resources development are presented. These planning models are applied to a previously developed...
