Evaluation of "Dry Year Option" Water Transfers from Agricultural to Urban Use
(Texas Water Resources Institute, 1997-04)
This study investigated the economics of an Edwards Aquifer region "dry-year option" buyout directed toward decreasing agricultural water use in an effort to augment springflow. The research involved several phases. First, ...
Arsenate and Arsenite Retention and Release in Oxide and Sulfide Dominated Systems
(Texas Water Resources Institute, 1997-06)
Metal pollution of surface water resources in Texas is a significant problem, and is caused by the inflow of sediments from oil fields, old mines and industrial sites, and by the discharge of metal contaminated sewage and ...
Compilation of Diversity Factors and Schedules for Energy and Cooling Load Calculations, ASHRAE Research Project 1093, Preliminary Report, Literature Review and Database Search
(Energy Systems Laboratory, Texas A&M University, 1999-05)
In this report, the first report for the ASHRAE 1093-RP project, we present: (1) our
extended literature search of methods used to derive load shapes and diversity factors in the U.S.
and Europe, (2) a survey of available ...
Comparative Evaluation of Methods for Distributing Naturalized Streamflows from Gaged to Ungaged Sites
(Texas Water Resources Institute, 1999-08)
The investigation documented by this report consists of identifying, developing, and evaluating alternative approaches for estimating sequences of monthly naturalized streamflows at ungaged sites based on known naturalized ...
Volume-Duration-Frequencies for Ungaged Catchments in Texas
(Texas Water Resources Institute, 1996-03)
This report summarizes results from studies to determine relationships among the volume, duration and frequencies of floods in ungaged catchments in Texas. Methodologies were adopted for determining flood volumes at ...
Water and Solute Flow in a Highly-Structured Soil
(Texas Water Resources Institute, 1993-12)
Prevention of groundwater contamination by agricultural activities is a high priority in the United States. Water and contaminants often follow particular flow paths through the soil that lead to rapid movement of pesticides ...
Economic Impact of Withdrawing Specific Agricultural Pesticides in the Lower Rio Grande Valley
(Texas Water Resources Institute, 1993-01)
The Air, Pesticides, and Toxics Division of the Environmental Protection Agency (EPA) has encouraged all states to develop a plan to manage the use of pesticides to prevent application that would result in unreasonable ...
A Lumped Parameter Model for the Edwards Aquifer
(Texas Water Resources Institute, 1993-09)
A lumped parameter model has been developed to simulate monthly water levels and spring flows in the Edwards Aquifer. It is less complex and easier to use than the existing complex finite difference models for the Edwards ...
The Edwards Aquifer: An Economic Perspective
(Texas Water Resources Institute, 1993-03)
Business as usual has ceased to be an acceptable system for the Edwards because of the burden it imposes upon regional competitiveness and welfare. Nonrevisionist strategies such as surface water development and spring ...
Economic and Hydrologic Implications of Proposed Edwards Aquifer Management Plans
(Texas Water Resources Institute, 1993-03)
The Edwards Aquifer underlies a large region in south central Texas extending from west of Uvalde to Austin. The karstic aquifer supports irrigated agriculture in the western part of the region, provides the sole source ...
