The Development and Use of Policy Statements in River Simulation Models
There are a number of ways in which the physical operation of a river system can be expressed in simulation models. Most of the earlier simulation models have incorporated the operating...
The Law of the River: Policy Expression
The need to accurately represent the law of the Colorado river has heretofore precluded the use of any general purpose river basin simulation model. In order to overcome the inflexibility...
Object-oriented River System Simulation
This paper describes an object-oriented approach to river basin simulation modeling that is event driven rather than time driven as in most river system simulation models. At the heart...
RSS: A Construction Kit for Visual Programming of River Basin Models
With the ever increasing pressure on environmental resources, there exists strong interest in river basin models which can be used to simulate proposed policy alternatives. Traditionally,...
Seasonal Water Quality Management Given Sparse Data
An approach for designing robust seasonal water quality management programs for river basins with sparse or short flow records is presented. This approach uses Markov chain modelling and...
Water Marketing in Washington?The Next Step?
The state of Washington has been blessed with an abundance of water resources for its use, including the Columbia and Snake rivers, but with the listing of the Snake River Sockeye Salmon...
Real-Time Water-Control System for the Trinity River, Texas
To provide information for improved flood prevention and control in the Trinity river basin in Texas, we developed a real-time water-control system that (1) retrieves rainfall and streamflow...
Alternative Designs for Permanent Protection of the San Luis Rey River Aqueduct Crossings
The San Diego County water Authority was organized to provide an imported supply of water to the San Diego region. The sole source of the water to the Authority is Metropolitan Water District...
Impacts of El Ni?o in Western Washington
The climatic phenomenon called El Nino is described, and its impact on hydrologic conditions in western Washington is shown for two recent events. Impacts on water management during the...
The Potomac Experience?A Forerunner of DPS
Thirty years ago, dramatic events were about to begin in Potomac River basin with the publication of a report of study recommending 16 major reservoirs and hundreds of small ones to solve...
The James River Case Study
The James River was selected as a case study for the National Drought Study because it provided an example of an Eastern (riparian) river basin with relatively little storage, increasingly...
Demonstrating Competition for a Limited Resource in the Cedar/Green Basins
An object oriented model building tool is used to develop two river basin simulation models. The models will be used to help manage the water resource during dry years in the Cedar and...
Bringing People, Policies, and Computers to the Water (Bargaining) Table
Droughts have been defined terms of hydrometeorological terms; however, a Water Control Manager realizes that droughts are also a function of demands. During the drought of 1988, water...
Analysis of Operating Criteria: Multiple Lakes at Voyageurs National Park
An overview of lake and river regulation at Voyageurs National Park, which resides on the Minnesota-Ontario border, is given to demonstrate how water policy agreements can work. In 1905...
Monthly Water Balance for Blue Nile River Basin in Ethiopia
The objective of this study was to present existing stream flow data for the Blue Nile River and tributaries within the Blue Nile River basin in Ethiopia and to use that data to provide...
Upper Guadalupe River Authority, Texas?Innovative Solution to Long-Term Water Needs
Through conjunctive use of groundwater and surface water, the Upper Guadalupe River Authority (UGRA) has designed a water supply system for the City of Kerrville, Texas that saves 80 percent...
Small Area Water Demand Forecasting at the Salt River Project
The Salt River Project Small Area Water Demand Forecast (forecast) is designed to provide water resource planners with long-range water demand forecasts disaggregated by user type and...
Impact of Groundwater Management Act and CAP Water Supply on Agricultural Water Conservation Programs
Irrigation districts in central Arizona have increased the tax assessments for their farms to pay for distribution systems to deliver Central Arizona Project (CAP) water. Many farms must...
Agricultural Water Conservation Programs in the Lower Colorado River Authority
Rice irrigation is the largest application of water within the area served by the Lower Colorado River Authority, accounting for approximately 75 percent of total annual surface and ground...
The PULSEQUAL Model: Using Combinations of Simple Mathematical Equations to Evaluate Complex Storm Effects on Water Quality
Storm discharges (stormwater and combined sewer overflows) have transient and highly variable impacts on receiving waters. Simple water quality equations have been developed to accurately...
