Erosion and runoff measurements from semi-arid rangeland in southwestern USA: an overview
1987
Frasier, G.W. | Renard, K.G.
The research program at the Southwest Rangeland Watershed Research Center in Tucson, Arizona, USA, is aimed at obtaining information for assessing present and future water potential, developing water-management techniques, providing design concepts for flood and sediment control, evaluating nonpoint source pollution, developing rangeland revegetation techniqu1684es, and water-harvesting/runoff-farming techniques. Current studies are involved with (1) precipitation intensity and areal distribution; (2) infiltration and channel losses; (3) hydrologic balance of semi-arid rangeland watersheds; (4) runoff hydraulics and flood-water yield frequency relations; (5) erosion and sediment transport; (6) surface and groundwater quality; (7) vegetation manipulation and rangeland revegetation; and (8) water harvesting and runoff farming. Much of the research activity is focused on developing concepts and collecting data for use in modeling to extend the area of potential applicability of the research res
