Solving MWRA's Supply Issues Through Conservation
Facing a supply/demand imbalance where demand was exceeding supply by over 10%, MWRA acted to implement a balanced water conservation strategy. The strategy included leak detection and...
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...
Estimating Urban and Suburban Sewage Flows with Assistance of GIS Technology
The Massachusetts Water Resource Authority (MWRA), an agency created by the Massachusetts legislature to provide wholesale water and sewer services to the metropolitan Boston areea, is...
Modeling Variable Width Buffer Zones with a Geographic Information System
It is possible to gain significant protection of water resources from nonpoint pollution with buffer strips, but frequently a single width strip is not appropriate. Geographic information...
Water Planning Using an Expert GIS
The development of an expert geographic information system (expert GIS) for long-term regional water resources planning is discussed. The system is comprised of an expert system to capture...
Lunacy, Legerdemain or Levitation: Legal Assessment of the ASCE Model Water Code
The Water Laws Committee of the ASCE Water Resources Planning and Management Division established a Model State Water Code Task Committee in 1990 which has the task of preparing a text...
Evaluation of the Model Water Code from an Environmental Ethic Perspective
In order to allocate water in an equitable and orderly process, laws have been constructed. The two basic methods of allocation are 1) a market system and 2) a political system. In a market...
Interfacing with the Public on Water-Related Issues?What TVA is Doing
Management of the water resources of the Tennessee River Basin has been a primary responsibility of the Tennessee Valley Authority (TVA) since its creation almost 60 years ago. In the...
The 1991 Revolution in Water Management
A revolution in water management took place in California in 1991, the fifth consecutive year of drought. Deliveries from California's major water projects in 1991 were reduced 70 to 100...
Water Availability and Water Demand Study for the Citanduy River Basin, West and Central Java, Indonesia
This paper will discuss the water availability and water demands in the Citanduy River Basin located in West and Central Java, Indonesia. A program of development of water and other natural...
Computer Modeling Responsibilities for Municipalities
Municipal organizations are often faced with a complex set of water resource problems which can best be analyzed through the use of computer models. The development of such models can...
Habitat Simulation in United States, Britain, and France
The need to identify an instream flow requirement for water resources management exists in a number of countries. The use of habitat simulation in the United States, Great Britain, and...
Prediction and Sensitivity of Recharges Due to Rainfall
This paper evaluates two models for predicting recharges due to rainfall: i) a simple mass balance model, and ii) a numerical model using the commercial software, UNSAT1. The models differ...
We Need to Integrate Water Transportation and Environmental Protection Planning and Policy
There are important connections between environmental natural resources and transportation policies and programs. Such links between air quality and transportation have been recognized...
The Changing Alliance Between Navigational and Environmental Interests in the ACF Basin
Structural modifications imposed on the Apalachi-cola River for navigation, their environmental impacts and government actions to address these impacts are reviewed. Past structural modifications...
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...
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...
Reservoir Operating Rules for Maximum Hydropower Production
A procedure for testing the effectiveness of reservoir operating rules for real-time, multi-purpose reservoir operation is presented. Particularly, models that may be used to achieve maximum...
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...
Urban Nonpoint Source Control Strategies Outside North America
Control practices for urban nonpoint source quality management varies widely around the world. Many countries have instituted controls to a greater or lesser degree, and they vary in complexity...
