(Texas Water Resources Institute, 2002)In 1993, the Texas Water Resources Institute awarded a grant to Clyde Munster of the Agricultural and Biological Engineering Department of Texas A&M University. The grant was funded by the US Geological Survey and the ...
-
(Texas Water Resources Institute, 2002)The Texas Water Resources Institute awarded Jason Krutz a $1,000 Mills Scholarship in 2002. Jason was one of 17 students to receive these grants. As part of his graduate studies, Jason is involved in research to examine ...
-
(Texas Water Resources Institute, 2002)This paper compares alternate approaches to valuing the economic impact of irrigation water shortages from Mexican noncompliance with the 1994 treaty. The two methods compared are an average value-of-water approach, and ...
-
(Texas Water Resources Institute, 2002)Salado Creek in Bexar County, Texas is one of 65 streams listed as impaired water bodies for its high concentration of fecal coliform bacteria in the Clean Water Act’s 303(d) list. The Hydrological Simulation Program-FORTRAN ...
-
(Texas Water Resources Institute, 2002)The objective of this research was to develop a conditional reliability model that would support short-term river basin management activities in which consideration of current reservoir storage levels is important. The ...
-
(Texas Water Resources Institute, 2003)Brush control strategies have been implemented for many traditional grasslands that have been impaired by wooded species. However, little information is known concerning what site specific characteristics may be most ...
-
(Texas Water Resources Institute, 2003)The Texas Water Resources Institute awarded a Mill Scholarship to M.C. Sterling, Jr in 2002. This project describes five sensors for rapid monitoring of crude oil concentrations in an aquatic system. These measurements are ...

-
(Texas Water Resources Institute, 2002)Whole Effluent Toxicity tests predict individual responses, but do not measure natural population or community responses. Because southwestern U.S. rivers are often dominated by municipal effluents, more direct evaluations ...
-
(Texas Water Resources Institute, 2002)During the last several decades, human-related activities and populations have increased markedly along the Texas Gulf Coast, intensifying pressures on the water resources and ecosystems of this area. The Lake Corpus ...
-
(Texas Water Resources Institute, 2002)Approximately 25% of the nation’s housing units utilize on-site treatment and disposal systems. Mostly, on-site treatment consists of a septic tank-soil adsorption configuration, though surface disposal systems are used ...
-
(Texas Water Resources Institute, 2002)The purpose of this report is to evaluate a multi-year experiment conducted by the Lower Colorado River Authority (LCRA) in agricultural water conservation. During the 1980s and 1990s the LCRA implemented a four-component ...
-
(Texas Water Resources Institute, 2002)Evapotranspiration (ET) is defined as the combined loss of water by evaporation from soil and transpiration from plants. Depending on the geographic location, 60-80% of total annual precipitation is lost in the form of ...
-
(Texas Water Resources Institute, 2002)Our project explored the possibility of using metazoan fish parasites as an indicator of deleterious effects on stream biota due to non-point source pollution, which is associated with urbanization and development. Experiments ...
-
(Texas Water Resources Institute, 2002)The objective of this study is to develop an analytical method that uses readily available instrumentation and minimal sample preparation for the determination of stable lodine species at nanomolar concentration levels in ...
-
(TEXAS NATURAL RESOURCE CONSERVATION COMMISSION, 2002)Through support from the Texas On-Site Wastewater Treatment Research Council, a project to search the literature relative to caliche materials as a medium for treatment and disposal of wastewater has been conducted. It was ...
-
(Texas Water Resources Institute, 2002)The mechanisms of riparian development due to the presence of the PL-566 reservoir imposed flow and the dam have been initially described in this study based on observations of stream, soil, and vegetation water movement. ...

Effects of nursery environmental cycles on larval red drum (Sciaenops ocellatus) growth and survival (Texas Water Resources Institute, 2002)Red drum early larval stages migrate through coastal inlets and settle into shallow seagrass meadows within estuaries. This study describes environmental rhythms (ER) in red drum nursery habitats and evaluates their role ...
-
(Texas Water Resources Institute, 2001)This fact sheet was produced by TWRI Communications Manager Ric Jensen under a grant provided by the Texas On-Site Wastewater Treatment Research Council. The fact sheet describes resources available to communities, and to ...
-
Urbanizing Watersheds and Changing River Flood Dynamics: Implications for Urban Wetland Restoration (Texas Water Resources Institute, 2003)Urbanization alters river hydrology, morphology, water quality, and habitat and ecology. Most of these associated changes are due to an increase in impervious surface cover (ISC) throughout the watershed. But the spatial ...
