A Decision Support System for Water Quality Modeling
A prototype Decision Support System (DSS) has been developed to evaluate the environmental and economic consequences of alternative farming practices. This system was developed to help...
Highway Construction and a Trout Stream Relocation
In 1970, a ten-mile section of Traffic Route 15 in the northern portion of Lycoming County extending into Tioga County was under design as a two-lane limited access highway on four lane...
Optimal Capacity Expansion in Multi-Aquifer Systems
A deterministic optimization model is presented for analyzing the capacity expansion policies in multi aquifer systems. The response of the system is included in the optimization model...
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...
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...
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...
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,...
