Mathematical Models of Water Quality Parameters for Rivers and Estuatries
(Texas Water Resources Institute, 1972-10)
Estuaries represent an economically and biologically important part of our coast. These bodies of water are used as permanent homes or nursery grounds for many of the important forms of marine life. Estuaries also provide ...
The Texas Water Plan and its Institutional Problems
(Texas Water Resources Institute, 1973-01)
An expansion of tile supply of water and greater efficiency in its use are necessary for the future economic development of the state of Texas. Imported water, supplemental to that available in the state, is an important ...
Optimization of Water Use Efficiency Through Trickle Irrigation and the Stress Day Index
(Texas Water Resources Institute, 1974-12)
Water deficits reduce plant growth and subsequently, crop yields. Man has relied upon irrigation to overcome these crop water deficiencies. But since the present supplies of water are limited, more efficient irrigation ...
Decision Analysis on Water Resources Planning and Management for an Arid Metropolitan Center in West Texas
(Texas Water Resources Institute, 1973-10)
The demand by consumers for public-owned low-priced natural resources is essentially insatiable. When natural resources become scarce the public is agonized by the problem of making an optimum choice or choices from feasible ...
Costs of Land Subsidence Due to Groundwater Withdrawal
(Texas Water Resources Institute, 1974-07)
In recent years the area around Houston and Baytown, Texas, has been affected to an increasing degree by land subsidence. Sinking of the land surface has reached critical proportions in many areas, and subsidence of as ...
The Influence of Trickle Irrigation on the Quality of Irrigation Return Flow
(Texas Water Resources Institute, 1976-03)
The influence of trickle irrigation on the quality of irrigation return flow was investigated in a field study and by means of computer simulation models. Six undisturbed buried monolith lysimeters were utilized to quantify ...
Alternate Solutions to Water Resource Development -- A Case Study
(Texas Water Resources Institute, 1974-05)
This study was undertaken in an effort to develop procedural methodology for the consideration of alternative solutions for water resources development in a short period of time with a view toward reduction of total costs ...
Value of Irrigation Water with Alternative Input Prices, Product Prices and Yield Levels: Texas High Plains and Rio Grande Valley
(Texas Water Resources Institute, 1974-08)
Agriculture is a major income generating sector of the Texas economy. Irrigated agriculture is an important part of Texas agriculture and an "adequate" water supply is important in maintaining a viable agriculture. Irrigation ...
Increasing Water Use Efficiency Through Improved Orifice Design and Operational Procedures for Subirrigation Systems
(Texas Water Resources Institute, 1975-02)
Two mathematical models describing one-dimensional flow from buried sources and in unsaturated soils were developed. One considered the consumption of water by roots. For the assumed distribution of the root consumption ...
Water Quality Hydrology of Lands Receiving Farm Animal Wastes
(Texas Water Resources Institute, 1973-06)
A significant pollution potential from cattle manure has developed as a result of the cattle feeding industry progressing to large, high density feeding operations. Two major potential sources of pollution from beef feedlots ...
