Water Supply Planning Using an Expert Geographic Information System
(Texas Water Resources Institute, 1995-06)
An expert geographic information system (expert GIS) for long-term regional water supply planning has been developed. This system has been evaluated through a case study examining a l9-county study region in South Texas ...
Farmers, Lenders and Water Districts Response to Texas
(Texas Water Resources Institute, 1993-11)
There are 6.4 million irrigated acres in Texas with 80 percent irrigated from ground water and 20 percent irrigated from surface sources. This is compared to 8.6 million acres irrigated in 1979, a dramatic reduction. Total ...
Community Water Demand in Texas
(Texas Water Resources Institute, 1989-04)
Solutions to Texas water policy and planning problems will be easier to identify once the impact of price upon community water demand is better understood. Several important questions cannot be addressed in the absence of ...
An Analysis of the Effects of Sociodemographic Factors on Daily Per Capita Residential Water Use in Texas Cities
(Texas Water Resources Institute, 1988-02)
Water is a key resource of concern to residents and decision makers in the State of Texas and in many other parts of the United States. Careful planning for its use is of utmost importance for the State and the Nation. ...
Estimated Farm Level Benefits of Improved Irrigation Efficiency
(Texas Water Resources Institute, 1984-06-10)
There are about 15 million acres of cropland in the U.S. that are irrigated from aquifers which are incurring declining water levels (sloggett). This is primarily in the Great Plains Region where irrigation water is pumped ...
Economic Implications of Farmer Storage of Surface Irrigation Water in Federal Projects: El Paso County, Texas
(Texas Water Resources Institute, 1981-12)
The Bureau of Reclamation has approved a program for farmer storage of surface irrigation water in Elephant Butte Reservoir, New Mexico. This program would allow individual farmers to store part of their annual surface ...
Impact of New Irrigation Technology on the Texas High Plains: 1980-2020
(Texas Water Resources Institute, 1983-12)
Crop production on the Texas High Plains is constrained by limited and erratic rainfall, hence irrigation is important. Presently, 6 million acres, or 50% of regional cropland, are irrigated annually. Irrigation water is ...
Forecasting Water Use in Texas Cities
(Texas Water Resources Institute, 1987-08)
In this research project, a methodology for automating the forecasting of municipal daily water use is developed and implemented in a microcomputer program called WATCAL. An automated forecast system is devised by modifying ...
Particles in Surface Waters: Coagulation and Transport
(Texas Water Resources Institute, 1991-08)
Conventional water quality assessment and simulation of particles in natural waters focus on bulk concentrations of the suspended solid phase. These analyses rely directly or indirectly on a linear, 'average particle' ...
Economic Implications of Farmer Storage of Surface Water in Federal Projects: Elephant Butte Irrigahon District, Dona Ana and Sierra Counties, New Mexico
(Texas Water Resources Institute, 1982-12)
This study estimated the expected regional impact and economic feasibility of a proposed water accumulation or water saving option for agricultural producers operating in the Elephant Butte Irrigation District in southern ...
