Book Description
This dissertation describes the development of a decision support tool designed to facilitate and enhance collaborative binational decision making associated with integrated transboundary water quality planning and management in the Lower Rio Grande/Río Bravo. The Lower Rio Grande Water Quality Initiative Decision Support System (LRGWQIDSS) is the result of a multidisciplinary effort to integrate the results of qualitative social science research and traditional and novel engineering and geographic information systems (GIS) methods associated with the modeling, analysis, and visualization of watershed, water quality and natural resources data. The LRGWQIDSS incorporates information currently used by urban planning and natural resource management organizations working along the Texas-Mexico border area and provides a means to analyze and display the information in a way that is useful to institutional and noninstitutional actors involved in transboundary water quality planning efforts. The analysis of the institutional arrangements currently in place to protect water quality in the Lower Rio Grande/Río Bravo played an important role in the design and development of the LRGWQIDSS and its successful application. The tool’s development represents a case study in the importance of the role of institutional analysis in the successful development of decision support systems for transboundary water quality management

Master's Thesis from the year 1998 in the subject Environmental Sciences, The University of Texas School of Public Health, language: English, abstract: This project investigates the transport of sediment and associated contaminants through the lowerportion of the Rio Grande/ Rio Bravo International Watershed. A preliminary review of water quality, bed sediment, and reservoir sediment-coring data in the watershed reveals a complex hydrological system, with varying potential sources of contamination. Within the lower portion of the watershed (defined as from the dams at Elephant Butte Reservoir in New Mexico and Red Bluff Reservoir in Texas co the Gulf of Mexico) arsenic, lead, and mercury appear at levels and/ or trends which may be of concern. Through the use of a geographic information system, this project evaluates the extent of contamination from selected toxic substances, identifies potential sources and/ or naturally-occurring conditions for the contribution of these toxic substances, and evaluates the potential for using Geographic Information Systems to model the watershed. The project uses data collected over the thirty year period from 1966 - 1996 by the Texas Natural Resource Conservation Commission, the United States Geological Survey, the International Boundary and Water Commission, and the United States Environmental Protection Agency. The project utilizes water quality, bed sediment, sediment coring, land use, land cover, soils, water-quality permitting, precipitation, flow, and reservoir-release information to attempt to derive a model depicting the movement of sediment through the watershed. Because the United States federal government has not promulgated standards for sediment (as of 1998), the project references standards from both the State of Washington and Canada for screening of sediment quality.
