An Interindustry Model of El Paso and Hudspeth Counties, Texas
(Texas Water Resources Institute, 1976-04) -
Establishing Crop Acreage Flexibility Restraints for Subregions of the Texas High Plains
(Texas Water Resources Institute, 1977-01)Cropping pattern shifts in many aggregate linear programming (LP) models need to be constrained due to institutional, marketing machinery, and price uncertainty factors. The purpose of this study was to estimate constraints ... -
Influence of Vegetation Management on Yield and Quality Surface Runoff
(Texas Water Resources Institute, 1977-03)Water requirements for the United States will triple by the year 2000 (Water Resources Council, 19689. In Texas and many western states about 75% of the total water used is from ground water and this source in many areas ... -
Select Minerals and Potable Use of Reclaimed Wastewaters
(Texas Water Resources Institute, 1977-03)The long-observed relationships of an influence of drinking water mineral content on heart-circulatory deaths are developed to indicate that sodium -- when present in sufficiently high concentrations -- may be detrimental ... -
A Report on the Effectiveness of Texas Water Resources
(Texas Water Resources Institute, 1977-05)A readership survey conducted in May 1977 found that readers of Texas Water Resources find it useful, attractive and informative. The bulletin is published by the Texas Water Resources Institute to generate public awareness ... -
Outlook for Energy and Implications for Irrigated Agriculture
(Texas Water Resources Institute, 1977-09)Agriculture uses large quantities of energy to pump groundwater for irrigation. This means the cost of energy has important implications for the industry in terms of costs and profitability. Increases in the prices of ... -
Institutional Arrangements for Effective Groundwater Management to Halt Land Subsidence
(Texas Water Resources Institute, 1978)In the Upper Galveston Bay region of the Texas coastal zone, water from naturally replenished underground aquifers provides much of the freshwater supply for municipal, industrial and agricultural needs. The availability ... -
The Impact of Energy Shortage and Cost on Irrigation for the High Plains and Trans Pecos Regions of Texas
(Texas Water Resources Institute, 1978)The High Plains and Trans Pecos regions of Texas are semi-arid crop production regions located in the western part of the state. Relatively low levels of rainfall are supplemented by irrigation from groundwater supplies. ... -
Silvicultural Activities in Relation to Water Quality in Texas: An Assesment of Potential Problems and Solutions
(Texas Water Resources Institute, 1978-02-01)Southern forests are expected to supply a large portion of the Nation's future timber requirement. Projected demands on southern forests continue to exceed allowable cut. As an outgrowth of this demand, intensive management ... -
Economic Impacts of Controlling Soil-Loss from Silviculture Activities: A Case STudy of Cherokee County, Texas
(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 ... -
Optimal Operation of Large Agricultural Watersheds with Water Quality Restraints
(Texas Water Resources Institute, 1978-04)Improved technology is needed for use in properly managing large agricultural watersheds. Proper watershed management means selecting land uses that are appropriate for each subarea, using erosion control measures where ... -
A Cross-Sectional Investigation of the Determinants of Urban Residential Water Demand in the United States, 1960 and 1970
(Texas Water Resources Institute, 1978-05)This research was undertaken to specify and estimate a model relating household demand for urban water to its principal determinants. Four specific tasks were accomplished: 1. An appropriate economic demand model for ... -
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 ... -
An Economic Analysis of Erosion and Sediment Damage in the Duck Creek Watershed, Dickens County, Texas
(Texas Water Resources Institute, 1978-08)The Federal Water Pollution Control Act Amendments of 1972, Public Law 92-500, established a national goal of eliminating the discharge of pollutants into the nation's waterways by 1985. As a step toward that goal an interim ... -
An Economic Analysis of Erosion and Sedimentation in Lavon Reservoir Watershed
(Texas Water Resources Institute, 1978-10)Public Law 92-500 - the 1972 Federal Water Pollution Control Act Amendments - mandates the analysis of agricultural non-point source (NPS) pollution controls. This report presents the results of a study of the economic ... -
Erosion and Sediment Damages and Economic Impacts of Potential 208 Controls: A Summary of Five Watershed Studies in Texas
(Texas Water Resources Institute, 1979-01)This report summarizes results of economic analyses of erosion and sedimentation in five agricultural watersheds in Texas (see fig. 1). Economic analyses of the study areas considered both the on-farm economics of soil ... -
Economically Optimum Irrigation Patternsfor Grain Sorghum Production: Texas High Plains
(Texas Water Resources Institute, 1979-03)Agricultural production and associated economic effects of irrigation on the Texas High Plains are seriously threatened by a rapidly declining groundwater supply and a swift upward trend in energy costs. To optimize the ... -
An Economic Feasibility Study of Irrigated Crop Production in the Pecos Valley of Texas
(Texas Water Resources Institute, 1979-03)Public concern over the potential effects of energy price increases on the U.S. food and fiber system has been dramatically justified in the Trans Pecos region of Texas where a 450 percent increase in the price of natural ... -
The Economic Value of Irrigation Water in the Western United States: An Application to Ridge Regression
(Texas Water Resources Institute, 1979-03)Reliable estimates of the demand characteristics of irrigation water are crucial to successful water policy formulation in the West. Although various studies concerning irrigation water demand exist in the literature, most ... -
