(Texas Water Resources Institute, 1982-08)Trickle irrigation is the most efficient method of irrigating peach orchards in Texas. With a trickle irrigation system, a producer may make full use of a limited or low-volume water supply to apply precise amounts of water ...
-
(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 ...

-
(Texas Water Resources Institute, 1972-10)Estuaries represent an economically and biologically important part of our coast. These bodies of water are used as permanent homes or nursery grounds for many of the important forms of marine life. Estuaries also provide ...
-
(Texas Water Resources Institute, 2011-04)This report summarizes the results of seepage loss rate tests conducted in La Feria Irrigation District Cameron County Irrigation District No. 3 (La Feria). These tests were conducted during April 9 - 11, 2003 on Canal 6.0.

-
(Texas Water Resources Institute, 2011-04)Seepage and loss rate tests were conducted in Hidalgo County Irrigation District No. 2 (HCID2) on four segments of Lateral A during September 2002 and January 2003. Table 1 summarizes the results of this study. Also given ...
-
(Texas Water Resources Institute, 2003)To accommodate projected increases in the demand for water, the Texas Water Development Board (TWDB) adopted the Texas Water Plan in 1997. The Texas Water Plan identifies Allens Creek as a potential reservoir site to supply ...
-
(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, 1968-12)The hydrometeorologist is often confronted with the problem of determination of precipitable water in the atmosphere based on surface dewpoints and the assumption of a saturated atmosphere with a pseudoadiabatic lapse rate. ...
-
(Texas Water Resources Institute, 2011-12)The region of Texas along the Mexican border has been experiencing rapid urban growth. This has caused fragmentation of many irrigation districts who are struggling to address the resulting challenges. In this paper, we ...
-
(Texas Water Resources Institute, 1973-06)One of the most perplexing problems in the United States today is concerned with providing the public services required in rapidly-expanding urban areas. A substantial portion of the total public service problem in the ...
-
(Texas Water Resources Institute, 1972-06)In Chapter I of this report a model of a single multi-purpose reservoir with stochastic inflows is addressed. The objective of the model is the development of an optimal operating policy for given time sequence of minimum ...
-
(Texas Water Resources Institute, 1975-05)With rapidly changing conditions in production agriculture, the need for highly flexible and quickly applicable methods of analysis is emphasized. The purpose of this study was to develop such a model for a homogeneous ...
-
(Texas Water Resources Institute, 2012-12)A popular approach currently applied in the development of Watershed Protection Plans (WPP) and Total Maximum Daily Loads (TMDL) is to identify whether point or non-point sources are the primary pollutant contributors in ...
-
(Texas Water Resources Institute, 2012-12)The Spatially Explicit Load Enrichment Calculation Tool (SELECT) methodology developed by Biological and Agricultural Engineering Department and Spatial Sciences Laboratory at Texas A&M University was used to independently ...
-
(Texas Water Resources Institute, 2000-12)A GIS-based hydrological/water quality model called Non Point Source Model (NPSM) was used to simulate various physical, chemical and biological processes taking place in the Leon Creek Watershed, near San Antonio, Texas. ...
-
(Texas Water Resources Institute, 2012-05)Drainage ditches are widely used for agricultural water management to help remove excess water from fields, which mitigates the effects of water logging and salinization. These ditches act as a direct hydraulic link between ...
-
(Texas Water Resources Institute, 1993-08)The Brazos River Basin is representative of several major river basins in the Southwestern United States in regard to natural salt pollution. Geologic formations underlying portions of the upper watersheds of the Brazos, ...
