Instream Flow Studies: Susquehanna Basin and Pennsylvania
Proposed methodology for developing regional criteria for determining instream flow needs are described. The methodology includes: classification of streams; reconnaissance level studies...

Lake Ontario Regulation Utilizing an Expert System Approach Constrained by Interest Satisfaction Relationships
Mass balance of historic and predicted total basin supplies to Lake Ontario forms the basis of an Expert Systems model constrained by interest satisfaction (IS) relationships. The IS Model...

Willingness and Ability to Pay for Rural Water
Estimates of willingness to pay for rural water systems were developed in South Dakota, Oklahoma, and Montana from responses to contingent valuation surveys. Ability to pay was also estimated...

Lewis and Clark Rural Water System: A Regional Approach to Solving Domestic Water Supply Problems for a Tri-State Area
The proposed Lewis and Clark Rural Water System (L&CRWS) is a treated, bulk water delivery system. Membership includes twenty-two communities and rural water systems in southeastern...

Determinants and Trends in Water Right Market Prices
As the demand for existing water supplies continues to grow, increasing attention is being placed on transferring water rights through markets for urban uses. Transfers are proposed as...

Reservoir Operation Using Bayesian Inferencing and Balancing Rules
The water resources problem addressed in this paper is real-time, multi-purpose reservoir operation. Specifically, daily, or at the most, weekly operations are considered. A hybrid modeling...

Optimal Groundwater Reclamation with Captial Costs
A dynamic optimal control model for groundwater remediation was extended to incorporate treatment facility capital costs. Incorporation of the capital costs had the greatest impact on...

Optimization of the Design and Operation of Soil Vapor Extraction Systems
Volatile organic compounds (VOC's) immobilized within the soil unsaturated zone constitute a significant source of groundwater contamination. Soil vapor extraction systems (SVES's), which...

The Application of Streamflow Duration Curves in Water Resources Engineering
Streamflow duration curves are a useful graphical and analytical tool for illustrating the relationship between the frequency and magnitude of daily streamflow. They are commonly used...

Hydraulic Properties of Surface Runoff on Ash-Mixed Concrete Pavement
The disposal of incinerated sludge ash from wastewater treatment plants is becoming an increasingly difficult problem in highly populated cities. The feasibility of reusing sludge ash...

Exploring Management Alternatives with Interactive Simulation
A drought exercise was held to disseminate information about a proposed change in reservoir management. In the drought exercise, an interactive operations model was used to simulate drought...

Fort Bend County Surface Water Supply Study
Fort Bend County encompasses approximately 876 square miles in southeast Texas near the Gulf of Mexico. The County's sole source of potable water is groundwater, which supplied 28 million...

Changing Dam Operating Criteria to Accommodate Aquatic Biological Diversity
The Colorado squawfish, bonytail chub, humpback chub, and razorback sucker, now threatened with extinction, were once the dominant fishes in the river. Recovering these native species...

Instream Flow Policy: An Alternative to Minimum Flowby
The limitations of current instream flow policies based on the concept of minimum flowby are discussed. An alternative policy based on sharing the available resource among competing uses...

Water 2050-Supply for the Portland, Oregon Metropolitan Region Using the Integrated Resource Planning Process
This paper presents information about the long range regional water supply planning work that is being conducted in the Portland, Oregon metropolitan region. An integrated resources planning...

Salt River Project Strategic Water Resource Plan
This paper discusses the results of the Salt River Project Strategic Water Resource Plan - Phase I: Assessment & Potential Strategies. The objective of Phase I of the Strategic...

Thoughts of Reservoir Management Studies
Changing water use patterns and priorities, the high cost and uncertainty of developing new supply sources, increasingly stringent environmental regulation, and the desire and need to...

Sustainable Management of Existing Reservoirs
Instead of a design and planning of new reservoirs in the future, more emphasis will be placed on the management of existing reservoirs. Reservoir storage reallocation and reassessment...

Mitigation of Non-Point Source Pollution Impacts on Groundwater Aquifers: A Case Study
This paper presents methodologies applied to a regional-scale project to study the potential impacts of storm runoff on groundwater aquifers that store sole source water supplies in Morris...

Site Characterization by Artificial Neural Networks
Recently, an optimal groundwater management model has been developed to treat groundwater remediation problems at Lawrence Livermore National Laboratory (LLNL). The objective of the model...
