Technical Abstract: The Precision Agricultural Landscape Modeling System (PALMS) is a terrain and weather driven, and distributed parameter hydrological-biophysical model primarily used in the Midwestern United States. Recently, research was started to evaluate the effectiveness of PALMS on irrigated and on dryland cropping systems in the semiarid Southern High Plains (SHP) of Texas. A further objective has been included to determine if PALMS can simulate the effect of row orientation on the surface hydrology and rainfall capture in dryland agricultural fields.Two dryland locations under cotton and grain sorghum production in Dawson County, Texas were selected to study the effects of circular planting pattern on the surface hydrology and rainfall capture in semiarid dryland cropping systems.
