Transactions of the American Society of Agricultural Engineers. 46(5):1381-1388. Interpretive Summary: Knowledge of rainfall properties allows decision makers to best utilize the occurrence of natural rainfall events because rainfall ultimately determines surface and groundwater supplies. Therefore, knowledge of historical rainfall patterns is necessary to make informed decisions and predictions about future water supplies for agricultural, industrial, ecological, and domestic needs. In the Texas Blackland Prairie, an important agricultural region with a large and increasing urban population, drought and excess rainfall can be experienced throughout the year. With the diverse demands placed on water resources in this region and an increasing demand resulting from an increasing population, water resource management will be an even more important issue in the future. Faced with these demands, the continuous rainfall record from the USDA-ARS Grassland Soil and Water Research Laboratory watersheds near Riesel, TX, should provide valuable information on long-term trends in rainfall intensity, frequency, and amounts.
