This week’s featured Western Waters Digital Llibrary item is “Hydrological Data and Peak Discharge Determination of Small Hawaiian Watersheds: Island of Oahu.” From the abstract, “Basic hydrological data including rainfall, runoff, historical flood, watershed characteristics, soil type, and land use of Hawaiian small watersheds on Oahu have been compiled and analyzed. Frequency analysis for annual peak discharge was made for 23 small watersheds on Oahu by using Gumbel’s extreme value theory. A regional flood formula has been derived for Honolulu and between mountain ranges of the island
of Oahu through the use of multiple regression.” This technical report comes to the WWDL from the University of Hawaii at Manoa’s Water Resources Research Center.

This week’s featured item is the report “The Impact of Energy Shortage and Cost on Irrigation for the High Plains and Trans Pecos Regions of Texas,” which comes to the WWDL from the Texas A & M University Repository and the Texas Water Resource Institute.
From the description, “The High Plains and Trans Pecos regions of Texas are semi-arid crop production regions located in the western part of the state. Relatively low levels of rainfall are supplemented by irrigation from groundwater supplies. These regions produced 51 percent of the cotton, 42 percent of the grain sorghum, and 48 percent of the wheat produced in Texas in 1974 (Texas Crop and Livestock Reporting Service). Considering only irrigated production these percentages were 75, 85, and 91 percent of Texas irrigated crop production for cotton, grain sorghum and wheat respectively. The importance of the High Plains and Trans Pecos regions to Texas crop production are not limited to these three crops, however, these statistics do serve to illustrate the significance of these regions in the Texas agricultural economy.”

Today we are featuring a technical report from the Texas A&M University Repository. “The 1997 Irrigation Suspension Program for the Edwards Aquifer: Evaluation and Alternatives” focuses on the details of a pilot program by the EPA.
From the description “The EAA implemented a pilot irrigation suspension program in 1997 on 9,669 acres mainly in Medina and Uvalde counties with the objective of increasing springflow at Comal Springs, and providing relief to municipalities in meeting Critical Period (drought) Management Rules. The Aquifer region, however, experienced a wet Spring in 1997, so that even irrigators not enrolled in the program applied little or no irrigation water.”
