Item Analytical Techniques for Planning Complex Water Resource Systems(Texas Water Development Board, 1974-04) Texas Water Development BoardThis report describes the research experience of a state-level water planning and development agency ove the period 1965-1972. The Texas Water Development Board, constitutional water planning and development agency for the State of Texas, in this period initiated and conducted a sustained program of research that has developed techniques useful in decision-making believed to be generally applicable to water planning problems elsewhere. In this report, the conditions dictating the constraints and opportunities of the Texas Water Plan are described, the sequential steps in the research program and its results are outlined, and proposed facilities of the Texas Water System, major physical works component of the Plan, are used as an example for research and development of new planning techniques.Item Completion Report on Techniques for Evaluating the Effects of Water Resources Development on Estuarine Environments(Texas Water Development Board, 1978) Texas Water Development BoardThe research project was designed to provide a set of analytical techniques for use by water resources planners and decision-makers to assist in measuring and evaluating the effects of water resources development on estuarine environments. The techniques are designed to be sufficiently flexible to analyze many types of water development and management policies. This report describes: (1) the techniques developed by the Texas Water Development Board to measure the environmental impact of water resources development on estuarine environments, and (2) the application of these techniques to a prototype Texas River basin - estuarine system to demonstrate the methodology. At this time, results are not definitive but serve as valuable learning tool. Environmental effects of water development and management are examined by simulation models of stream, reservoir, and estuarine environments, and placed within a flexible analytical framework for evaluating a wide range of alternatives. An estuarine ecological model (ESTECO) and an estuarine model (MOM) for migratory organisms (Gulf shrimp) were developed for use with existing Board models that were designed to simulate stream, reservoir, and river basin conditions as water use demands increase on projected scales. The test case was executed on the Guadalupe Estuary and its major contributing drainages, the San Antonio and Guadalupe River Basins. Year 2000 simulations indicate water use projections would increase frequency of low flow events with varying environmental effects.Item Freshwater inflows to Texas bays and estuaries: Ecological relationships and methods for determination of needs(Texas Water Development Board and Texas Parks and Wildlife Department, 1994) Texas Water Development Board; Texas Parks and Wildlife Department;Two main themes are examined in this report: 1) demonstrating the effects of freshwater inflows on living and non-living components of estuarine ecosystems and 2) presenting a methodology for assessing the freshwater inflow needs of Texas bays and estuaries that satisfies the requirement of maintaining an ecologically sound environment and the productivity of fish, shellfish, and other estuarine life.

This is the draft version; the final report is cited as Acc# 8367.Item Galveston Bay national estuary program.(Galveston Bay National Estuary Program., 1990) Texas Water Development Board;There are several numerical models currently available for simulating circulation, salinity and sedimentation patterns in coastal bays and estuaries; however, judging their applicability requires delineation of the criteria used in evaluating the models. The Bay Modeling Subcommittee of the Scientific/Technical Advisory Committee to the Galveston Bay National Estuary Program offers the following criteria: (1) Spatial capability, (2) Temporal capability, (3) Input capabilities, (4) Physical formulation, (5) Boundary conditions, (6) General numerical efficiency of the model code, and (7) Successful application to other estuarine systems and a measure of transportability of the code (with adequate user documentation).Item A Homeowner's Guide to Water Use and Water Conservation(1990) Texas Water Development Board; ;No abstract availableItem National Water Assessment State Regional Future Texas Gulf Region(Texas Water Development Board, 1975) Texas Water Development BoardThis report is the second in a series of four reports which will set forth information relating to the U.S. Water Resources Council's specific problem analysis portion of the 1975 National Water Assessment for the Texas Gulf Region. The purpose of the specific problem analysis is to identify, describe and compare from a State and regional viewpoint the severity of specific water related problem issues and areas. This report pertains to the specification of the State Regional Future information for the Texas, New Mexico, and Louisiana parts of the Texas Gulf assessment region while the first report pertained to the identification of severe water and related problems in the same area. The third report will contain information describing the effects of not solving severe water and related problems while the fourth and final report will specify detailed conclusions and recommendations regarding the resolution of severe water and related problems. In accordance with the U.S. Water Resources Council's guidelines for developing the State Regional Future, the following information has been included as the State Regional Future for the Texas Gulf assessment region. 1. State Regional Desires and Objectives - Statement of broad social, economic and environmental goals to which the citizens of the region aspire. 2. Environmental Resources and Non-Volumetric Requirements - A map and narrative display of important features of the Regional environment. 3. List of Water and Related Problems - A list of problems for which implications, conclusions, and recommendations will be evaluated in detail in forthcoming assessment activities as well as a completed summary problem characterization matrix for each problem and a map indicating the location of problem areas. 4. Socioeconomic Characteristics - A tabular summary of present and future socioeconomic characteristics of each ASA including population, employment, earnings, and land use.Item Preliminary feasibility and economics of desalting brackish waters in candidate areas of West Texas(Ralph M. Parson Company, 1968) Ralph M. Parson Company; US Office of Saline Water; Texas Water Development Board;This study, initiated in June, 1967, wsa conducted by The Ralph M. Parsons Company for the Texas Water Development Board under the Board's contract with the Office of Saline Water, US Department of the Interior. The purpose of this study is to obtain information on the type and characteristics of desalting plants more suitable to the treatment of saline waters in West Texas and to compare the economics of desalting these saline waters with the alternative sourcse of water supply. The Office of Saline Water needs this type of information to assist in guidance of its research and development program on processes for low-cost desalting and to further advance the development of methodology for effectively comparing the economics of desalting with alternative means of providing potable water in a variety of locations and water demand circumstances. The Texsa Water Development Board has need for this information in developing part of the comprehensive long-range water plan for Texas. This report presents the results of the study of the preliminary engineering economics of supplying municipal and industrial water from desalting plants in 2 to 20 MGD size range on candidate areas of West Texas.Item Rules, Regulations and Modes of Procedure relating to the Texas Weather Modification Act(Texas Water Development Board, 1976-04) Texas Water Development BoardThe Rules contained herein are adopted for the purpose of promoting continued research and development in the science and technology of weather modification, minimizing the danger of weather modification activities to health and property, simplifying procedures, avoiding delays, saving expenses, and facilitating administration and enforcement of Chapter 14 (Weather Modification) of the Texas Water Code, and these Rules shall be construed accordingly.Item Texas Water Facts(Texas Water Development Board, 1991) Texas Water Development BoardTexas Water Facts is a primer on water in Texas, a way to gain an understanding and appreciation of one of Texas' most valued and interesting natural resources.Item Trans-Texas Water Program: southeast area: draft screening report: environmental analysis of potential transfer routes(1998) Freese and Nichols, Inc.; Texas Water Development BoardThis report determines the preferred alternative alignment for transfer of water between the Sabine, Neches, San Jacinto, Trinity, and Brazos rivers through analysis of environmental issues along each potential transfer segment. Each segment's existing environment is described in terms of segment length, compatible land use, threatened and endangered species, stream and river crossings, wetlands, water quality, soils, geology, public lands and traffic. Sensitive natural communities, vegetational areas, fisheries, and cultural resources in the vicinity of the segments are also discussed.Item Trans-Texas Water Program: southeast area: technical memorandum: Galveston Bay freshwater inflows study(Brown & Root, Inc.; Freese & Nichols, Inc., 1998) Texas Water Development Board;This technical memorandum describes the water availability studies that have been conducted to date. The objective of this study is to develop preliminary estimates of freshwater inflows into the bay under three different inflow scenarios: naturalized conditions, current conditions and future conditions. ... These three scenarios were selected to relate current and future water rights conditions to the State of Texas analysis. This study analyzes the statistical frequency of certain hydrologic flow conditions occurring within Galveston Bay. The Galveston Bay watershed contains 33,000 square miles and consists of the following two river basins and three coastal basins: Trinity River, San Jacinto River, Neches-Trinity Coastal, Trinity-San Jacinto Coastal, and San Jacinto-Brazos Coastal. The commonly referenced Galveston Bay actually consists of four separate embayments, including: Galveston Bay, Trinity Bay, East Bay, and West Bay. Data prepared for the Texas Bay & Estuary Program suggests that the Trinity and San Jacinto rivers typically contribute in excess of 80% of annual freshwater inflows into Trinity Bay and Galveston Bay while the coastal river basins primarily contribute freshwater inflows into East and West Bays.Item Water for Texas, today and tomorrow(Texas Water Development Board, 1990) Texas Water Development Board; ;NOT AVAILABLE IN HOUSE EASItem Water for Texas: a consensus-based update to the state water plan. Volume II: Technical planning appendix(Texas Water Development Board, 1997) Texas Water Development Board;The amended 50-year state water plan describes current and prospective water uses, identifies water supplies and matches these supplies to water uses.
