New Project, Publications/Papers and Training Courses

New TWRI project

The Texas Water Resources Institute recently acquired funding for the following new project:
  • Evaluation and Demonstration of BMPs of Cattle on Grazing Lands for the Lone Star Healthy Streams This project is designed to evaluate the effectiveness of best management practices designed to reduce bacterial contamination caused by grazing livestock in Texas water bodies and to use this information as the scientific-basis for the Lone Star Healthy Streams (grazing cattle component) education program Principal Collaborators: Texas State Soil and Water Conservation Board, Texas Water Resources Institute, Texas AgriLife Extension Service, Texas AgriLife Research, cooperating ranches Funding Agency: Texas State Soil and Water Conservation Board

New Publications/Papers

Initial Evaluation of Smart Irrigation Controllers: Year Two (2009) results, Charles Swanson and Guy Fipps, Texas Water Resources Institute TR-364, 2010.

A smart controller testing facility was established by the Irrigation Technology Center at Texas A&M University in College Station in 2008. A two-year testing program was initiated in order to evaluate smart controller testing methodology needed to determine their performance and reliability under Texas conditions from an “end-user” point of view. The “end-user” is considered to be the landscape or irrigation professional (such as a Licensed Irrigator in Texas) installing the controller. During the first year (2008), six (6) controllers were evaluated over a 60-day period. Details were provided by Swanson and Fipps (2008). This report details the results of the second year (2009) evaluations.

Supplement to Diagnosis and Management of Salinity Problems in Irrigated Pecan Production: Salt Leaching, S. Miyamoto, Texas Water Resources Institute TR-387A, 2010.

In the publication prepared in 2006 (TWRI TR-287), we described ways to diagnose salt problems which affect irrigated production of pecans. We also discussed the concepts of minimizing soil salinization, and ways to lower soil salinity. However, the materials presented were general and introductory in nature. This article is to supplement the previous publication with technical details, and practices of salt leaching during the routine irrigation as well as salt leaching irrigation for restoration.

Questions about Groundwater Conservation Districts in Texas, Bruce J. Lesikar, Valeen Silvy, Ronald A. Kaiser, Texas AgriLife Extension Bookstore, B-6120, June 2010 (re-print).

Groundwater conservation districts (GCDs) are being created in many parts of Texas to allow local citizens to manage and protect their groundwater. This publication answers frequently asked questions about groundwater and GCDs. (44 pp., 4 figures)
