Using GIS to Develop 2-D Hydraulic Models
As communities along rivers and streams continue to develop, the demand for more accurate floodplain analysis and flood warning will also increase. Computer systems continue to develop...

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...

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...

Design and Implementation of an Optimal Real-Time Hydropower Generation Scheduling System for the Lower Colorado River in Texas
The Lower Colorado River Authority (LCRA) of Texas supplies water and electric power to over 800,000 persons in Central Texas. A real-time decision support system is being developed and...

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...

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...

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...

Effects of Climate Change on Water Quality
This research explores the potential effects of climate change on the quality of waters in lakes. Temperature and dissolved oxygen were considered the primary water quality variables due...

A Decision Support System for Administering Water Rights in an Alluvial Aquifer
A previously developed basin scale surface-ground water simulation model has been incorporated into a micro-computer based decision support system that simulates the transient ground water...

Application of the PCRSS Reservoir Simulation Model to the Salt River Project
PCRSS is a general purpose reservoir system model construction kit. It allows the user to specify the system configuration and parameters through the use of a windows based graphic user...

Colorado River Decision Support System
Colorado is developing its own tools, such as the Colorado River Decision Support System (CRDSS), to evaluate alternative strategies and establish an informed and factual position regarding...

Instream Flow Strategies for Operation of the Federal Central Valley Project
Federal Central Valley Project (CVP) operations and policies of reservoir storage and river releases for fish and wildlife protection and restoration are discussed. Prescribed strategies...

Impacts of Natural and Manmade Changes on the San Luis Rey River Environment
Almost all rivers continually change their position and shape based on various geomorphic and hydraulic factors, caused by natural as well as manmade activities on the riverine environment....

Monitoring Water Quality and Use in Colorado
This paper presents the results of a two year study on the impact of irrigation water use on water quality near Greeley, CO. Data on irrigation application efficiency, deep percolation,...

Changes of Water Rights - The Colorado Experience
This paper describes engineering efforts which are involved with the judicial changes of water rights in the State of Colorado....

Evaluation of the Pagosa Springs Geothermal Reservoir and Implications of Potential Additional Reservoir Development
The Town of Pagosa Springs is located 280 miles from Denver on the north bank of the San Juan River in southwest Colorado as shown on the Index Map, Some time before 1920 the first well...
