Optimizing Dallas' Multiple Reservoir Supply System
Dallas Water Utilities (DWU) applies a mathematical computer model of its reservoir supply system to assist in making operational decisions to optimize supply operations. The model considers...
Economic Benefits of a Flood Warning System?The Ventura County, California Experience
Since the spring of 1979, Ventura County has been receiving the benefits of a growing Flood Warning System (FWS). Beginning with six self-reporting raingages, two untested flow models,...
Fort Worth: Where the West Began with Water
This paper presents a historic overview of the impact the Trinity River has had on the development of Forth Worth with regard to fire protection, water supply and flood control....
The Genesis of Surface Water for San Antonio
San Antonio is the ninth largest city in the United States and the only one of that group that relies exclusively on groundwater. The Applewhite Water Supply Project is the first surface...
The Dallas Floodway?Past and Present Successes in Flood Protection Benefits
This paper explores the history of the Dallas Floodway, past performance of the project under various flood conditions and, most recently, the present successes in flood protection provided...
Water Reuse in Las Colinas, Irving, Texas
The largest urban water reclamation project in Texas that involves reuse of treated wastewater was implemented in July 1987, to provide an economical and drought-free supply of water to...
Evaluation of Global Warming Impact on Soil Moisture and Water Runoff in Texas
In this paper a numerical evaluation of the variability of soil moisture and surface runoff due to global warming is carried out. An analytical model of the soil moisture balance based...
Groundwater Contamination from an Unlined, Poorly Capped Landfill
This paper presents a case study of groundwater and surface water contamination from a major, unlined, and poorly capped municipal landfill located in Western Washington. The landfill...
The Market Value of Water in the Ogallala Aquifer as Implied by Recent Farm Sales
As indicated by farm sales in the Ogallala region, the value of water in the Ogallala Aquifer has fallen. Market values have declined by 30 to 60%, following the recent downward trends...
Old Ideas, New Applications: Expanding the State of the Practice
This paper describes three projects in which analytical tools were developed to assist decision makers in operating large-scale water resource systems. Position analysis models were developed...
Reservoir Operations by Fuzzy Goal Programming
The reservoir operations problem is composed of obtaining optimal releases, and storages of a reservoir and downstream reach routed flows based on forecasted inflows and precipitation....
Using an Index Stream to Make Instream Flow Decisions
The paper discusses development of an Integrated Operating Plan (IOP) that uses an unregulated (natural) stream in the upper Cedar basin as an index of overall hydrologic status of the...
Estimating Lake Inflows for Storage by Linear Programming
The Lower Colorado River Authority (LCRA) recently completed a Water Management Plan for the lower Colorado River Basin in Texas. In developing the Plan, a daily river flow routing procedure,...
Reservoir Reevaluation in TVA
Demands for the use of dams and reservoirs tend to change after the projects are completed. The Tennessee Valley Authority (TVA) works with State and local groups to try to increase the...
Estimating Earthquake Hazard of Municipal Water Systems
This paper uses the City of Memphis as a case study to present the seismic hazard evaluation of a municipal water delivery system. The horizontal peak bedrock accelerations resulting from...
Water Measurement and Accounting of Lake Michigan Diversion
The diversion of water from Lake Michigan and the Lake Michigan Basin into the Mississippi River Basin has been regulated since the turn of the century. The U.S. Supreme Court Decree of...
Measuring Benefits of Water Supply Projects
Various approaches are used to determine the value of water supply projects. Deterministic methods will lead to biased valuation of additional supplies of water. Calculation of risk premium...
Abilene, Texas, Flood Control Study?Cast History
The Corps of Engineers, Fort Worth District, is currently performing a study of flooding problems of Abilene, Texas. This is the first study under the General Investigations authority...
Some Hydrological Impacts of Climate Change for the Delaware River Basin
To gain insight into possible impacts of climate change on water availability in the Delaware River, two models are linked. The first model is a monthly water balance model that converts...
Predicting Effects of Global Climate Change on Reservoir Water Quality and Fish Habitat
This paper demonstrates the use of general circulation models (GCMs) for assessing global climate change effects on reservoir water quality and illustrates that general conclusions about...
