Caliche Soils as a Filter Medium for Treatment and Disposal of Wastewater
(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 ...
Effect of Irrigation Application Devices on Boll Set, Cotton Yield and Fiber Quality
(Texas Water Resources Institute, 2002)
Previous research concluded that water sprayed above the canopy on open flowers interrupted pollination causing
flower drop and subsequent reduction in boll set and lint yield. The effect of water delivered through three ...
Irrigating Cotton with Salty Water and Subsurface Drip Irrigation
(Texas Water Resources Institute, 2002)
An experiment with a Subsurface Drip Irrigation system was planned on a Texas farm with salty water to develop design and management recommendations for SDI systems. The objectives of this study were: 1) Compare 0.20 and ...
Desalination of Produced Water Using Reverse Osmosis
(Texas Water Resources Institute, 2002)
Many oil and gas wells, particularly those in mature fields, produce large amounts of brine along with the hydrocarbons. Disposing of the brine can be costly, due to its composition and large volume. For example, in the ...
Site Specific Management of Row and Vegetable Crops with Center Pivot Irrigation Under Traditional and Conservation Tillage
(Texas Water Resources Institute, 2002)
In March of 2002, Nyland Falkenberg was awarded a $5,000 grant from TWRI to work with researcher Giovanni Piccinni at the Texas A&M Agricultural Research and Extension Center in Uvalde. The focus of this project, which is ...
Effect of Row Pattern and Spacing on Water Use Efficiency for Subsurface Drip Irrigated Cotton
(Texas Water Resources Institute, 2002)
Cotton production is an important economic base for Far West Texas; however, the region has erratic and limited rainfall and is dependent on limited groundwater supplies. Maximizing water use efficiency (WUE) for cotton ...
Conditional Reliability Modeling To Support Short Term River Basin Management Decisions
(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 ...
Arsenic Concentrations in Water Resources of the Choke Canyon/Lake Corpus Christi Reservoir System: Surface and Ground Waters
(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 ...
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. ...
