The objective of this paper is to evaluate the predictive capabilities of hydrologic models in estimating the magnitudes and frequencies of flood peaks by comparing them with the values of the discharge-frequency curve developed from observed peak flows at a gaging station. The hydrologic models considered in this paper are: the U.S. Army Corps of Engineers (USACOE) HEC-1 model, the U.S. Soil Conservation Service (SCS) TR-20 model, the Pima County Hydrology Method, the Rational Method and the U.S. Geological Survey (USGS) regression equations for Arizona. The case study uses a 560-acre watershed 63.004, a subwatershed of the semiarid Agricultural Research Service (ARS) Walnut Gulch Experimental Rangeland Watershed near Tombstone, Arizona.
