A Study of the Economic Impact of Water Impoundment Through the Development of a Comparative-Projection Model
(Texas Water Resources Institute, 1967-08)
Using two established reservoir projects, an economic simulation model for reservoir development was constructed. The two comparative areas used for the model development are both reservoirs in central Texas and were ...
Shallow Seismic Investigation of Hydrogeologic Problems in the Brazos River Alluvium, Texas A&M Plantation, Burleson County, Texas
(Texas Water Resources Institute, 1966-07)
Twenty-two shallow, reversed, seismic refraction profiles were conducted in the Brazos River floodplain to test the feasibility of using seismic methods to provide hydrogeologic information in this province. The specific ...
Identification of Management and Planning Problems of Urban Water Resources in the Metropolitan Area of Greater San Antonio
(Texas Water Resources Institute, 1971-09)
This interim report describes the research performed to date on Project A-017-TEX sponsored by the U. S. Department of Interior Office of Water Resources Research and the Texas A&M University Texas Water Resources ...
Water Use Efficiency in Plant Growth and Ambient Carbon Dioxide Level
(Texas Water Resources Institute, 1972-06)
This report examines the validity and explores the practical implications of the proposition that CO2 enrichment of the leaf environment enhances plant growth and, simultaneously decreases plant water use.
A theoretical ...
Influence of Transpiration Suppressants, Sprinkler Irrigation and Moisture Levels on Transpiration and Evapotranspiration
(Texas Water Resources Institute, 1970-05)
In 1968 and 1969, moisture level treatments were applied to tomatoes and citrus. Light sprinkler applications and white acrylic paint were applied to leaf canopies of tomatoes and citrus. Moisture use and yields as influenced ...
Water Transfer from Soil to the Atmosphere as Related to Climate and Soil Properties
(Texas Water Resources Institute, 1970-02)
Facilities and Systems - Design of the lysimetric facility of the project began in 1966. During 1967, soil cores were taken for the lysimeters, and in 1968 an unforseen temperature problem in the lysimeters was solved. A ...
Requirements for the Effective Use of the Water Resources Scientific Information Center (WRSIC) -- Determined by Field Evaluation
(Texas Water Resources Institute, 1969-11-15)
A study designed to analyze two information services provided by the Water Resources Scientific Information Center is described. The study was conducted to assess the monetary value and acceptability to users of the Selected ...
Population, Economy and Energy Use’s Influence on Sulfur Emissions in the United States Since 1900
(Energy Systems Laboratory (http://esl.tamu.edu), 1990-06)
This paper seeks to identify how changes in population, economic activity, and energy use have influenced sulfur emissions during this century. A linear model is presented which characterizes sulfur emissions as the product ...

(Texas Water Resources Institute, 1978-03-01)
Section 208 of the 1972 Amendments to the Federal Water Pollution Control Act (Public Law 92-500) requires the states to develop plans which: (1) contain processes to identify nonpoint sources of pollution, and (2) set ...
An Economic Analysis of Erosion and Sediment Damage in the Lower Running Draw Watershed
(Texas Water Resources Institute, 1978-08)
The development and implementation of agricultural non-point source (NPS) pollution control plans was mandated by the 1972 Federal Pollution Control Act Amendments, Public Law 92-500. The purpose of this particular report ...
