Uncertainty Analysis as a First Step of Developing a Risk-Based Approach to Nonpoint Source Modeling of Fecal Coliform Pollution for Total Maximum Daily Load Estimates
(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 ...
Rapid Risk Assessment of Watersheds and Dams using GIS and Modeling
(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. ...
Pimephales promelas and Laboratory Bioassay Responses to Cadmium in Effluent Dominated Systems
(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 ...
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 ...
Delivering Education Programs Focused on Stakeholder Needs to Address Agricultural NPS in the Arroyo Colorado Watershed FY 2014 CWA §319(h)
(Texas Water Resources Institute, 2016-07)
The focus of Texas State Soil and Water Conservation Board (TSSWCB) Project 15-53, “Delivering Education Programs Focused on Stakeholder Needs to Address Agricultural NPS in the Arroyo Colorado Watershed,” was to continue ...
Resources to Replace On-Site Wastewater Treatment Systems in Texas
(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 ...
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 ...
Determination of Regional Scale Evapotranspiration of Texas from NOAA - AVHRR Satellite
(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 ...
Effectiveness of Buffalograss Filter Strips in Removing Dissolved Metolachlor and Metolachlor Metabolites from Surface Runoff
(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 ...
Fundamentals of Water Availability Modeling with WRAP, 6th Edition
(Texas Water Resources Institute, 2011-09)
Water resources development, water allocation, and river/reservoir system operations are simulated with the Water Rights Analysis Package (WRAP) using sequences of historical naturalized stream flows and reservoir surface ...
