Economic and Conservation Evaluation of Capital Renovation Projects: Cameron County Irrigation District No. 2 (San Benito) – Infrastructure Rehabilitation – Preliminary
(Texas Water Resources Institute, 2003-07)
Initial construction costs and net annual changes in operating and maintenance expenses are identified for a five-component capital renovation project proposed by Cameron County Irrigation District No. 2, (a.k.a. San Benito) ...
Management Tools for Aquatic Systems: The Role of Periodic Hydraulic Disturbances on Planktonic Communities
(Texas Water Resources Institute, 2005)
Environmental disturbances in aquatic systems alter phytoplankton community structure, diversity and biomass (Hutchinson, 1961). For example, laboratory experiments and field studies have shown that episodic flushing and ...

Urbanizing Watersheds and Changing River Flood Dynamics: Implications for Urban Wetland Restoration
(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 ...
Disinfection Devices: Field Experiences
(2003)
Wastewater that is to be surface applied must first be disinfected to remove odors and disease-causing microorganisms. We are conducting a study, funded by an EPA 319 grant, determining the ability of subsurface flow ...
An Analysis of the Economic and Financial Life-Cycle Costs of Reverse-Osmosis Desalination in South Texas: A Case Study of the Southmost Facility
(Texas Water Resources Institute, 2009-09)
Desalination provides a supply alternative for potable water for many communities, along with possible defenses against security threats potentially affecting clean water supplies. The economic and financial life-cycle ...
Groundwater in the Great Plains
(Great Plain Agricultural Council, 2003)
Groundwater lies hidden beneath the soil, out of sight and largely out of mind. As a result, it’s poorly understood by most who depend on it for drinking water and other uses. Misconceptions about groundwater are common. ...
Field Instruments for Real Time In-Situ Crude Oil Concentration Measurements
(Texas A&M University, 2003-06)
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 ...
