Land-Water Management: Theory and Practice
Policies for land and water management should be consistent and coordinated. Traditionally, land use and water management decisions have been made by different levels of government and/or...
Changing Land Uses in the Platte and Arkansas Basins
Several water disputes among various parties in the Platte and Arkansas River Basins may have significant impacts on future land use practices. This paper describes five cases being litigated...
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...
Microcomputer Tools for the Management of a Multiple Reservoir Water Supply System
In a Raw Water Management Plan study performed for the City of Newport News Waterworks, Camp Dresser & McKee developed a series of micro-computer programs that allow the City to...
Storage Reallocation Evaluation for Reservoir System
Reservoir storage capacity is allocated to various purposes prior to project construction. However, changing needs and conditions may warrant later conversion of storage capacity from...
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,...
Benefit/Cost Analysis of Stormwater Detention Systems
In the past, detention basins have been designed to control peak discharge rates. However, there is considerable interest in using the detention basin for control of nonpoint source pollution....
Reliance on Structural Controls for Water Supply Protection in Urbanizing Watersheds
The watershed is the source of pollutants which can contaminate the water supply reservoir. It is far preferable to implement an affordable watershed management plan that keeps contaminants...
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...
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...
Contributions of Satellite Imagery to Water Resource Evaluations
Satellite images may also facilitate the development and maintenance of regional Geographic Information Systems (GIS) by providing both a source of base map creation and update, as well...
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...
Is There a Future for Vacuum Sewers?
Vacuum sewers collect and transport sanitary sewage using pressure difference rather than gravity as the primary motive force. Compared to conventional gravity sewers, they use smaller...
