(Texas Water Resources Institute, 1993-12)Prevention of groundwater contamination by agricultural activities is a high priority in the United States. Water and contaminants often follow particular flow paths through the soil that lead to rapid movement of pesticides ...
-
(Texas Water Resources Institute, 2003)Throughout the spring and summer months of 1993, extended rainfall throughout much of the Midwestern United States caused record flooding that inundated much of the Upper Mississippi River Basin (UMRB). Precipitation in ...
-
(Texas Water Resources Institute, 2007-01)Red Bluff is the main reservoir of the Pecos River in Texas, and its maximum storage capacity adjusted to sediment accumulation is estimated at 357 million m3 (289,600 acre-ft.). Aside from the shortage of water entering ...
-
(Texas Water Resources Institute, 2002)Healthy rangelands are relatively efficient at conserving rainfall, but they may become dysfunctional in this regard as vegetative cover diminishes and aggregation of the surface soil layer is destroyed by overgrazing, ...
-
(Texas Water Resources Institute, 1983-08)Water shortages are a common problem in much of the southwest. Increasing urbanization and increasing population places greater demands on dwindling water supplies. Over half of the water used in urban areas of the southwest ...
-
(Texas Water Resources Institute, 2012-10-05)Soil sodicity is known to affect soil structural stability and permeability. However, the impact differs depending on salinity of irrigation water, soil types as well as irrigation management practices. This study examined ...

(Texas Water Resources Institute, 1971-02)Water resources planners and systems analysts are continually confronted with many complex optimization problems. Two major factors contribute to this problem. Firstly, mathematical modeling and system description capabilities ...
-
(Texas Water Resources Institute, 2012-10-01)WRAP simulates development, management, control, allocation, and use of the water resources of river basins. The WRAP modeling system documented by the basic Reference and Users Manuals (TR-255 and TR-256) is based on a ...
-
(Texas Water Resources Institute, 2011-12)WRAP is a generalized river/reservoir system simulation model providing flexible capabilities for analyzing water resources development, management, control, allocation, and use. The Texas Commission on Environmental Quality ...
-
(Texas Water Resources Institute, 1996-10)The evolution of the Water Rights Analysis Package (WRAP) is outlined in the "Model Development Background" section of Chapter 1 of this report. The model was developed in conjunction with a series of university research ...
-
(Texas Water Resources Institute, 2012-10-01)The WRAP modeling system is documented by Reference and Users Manuals (TR-255 and TR-256) and other auxiliary manuals (TR-317 and TR-430) required to apply particular features. The WRAP executable programs are applied by ...
