Abstract:
Riparian areas are important ecosystems in rangelands. Surface runoff and soil loss from the ungrazed and grazed areas of sheep Creek Colorado, U.S.A. were simulated using the Areal Non- Point source Watershed Environment Response Simulation (ANS-WERS) model. The ANSWERS model parameters were estimated from old measurements and published• literature. The mean runoff, soil loss, maximum erosion and maximum deposition rates simulated by the ANSWERS model were significantly higher (P50.05) for the grazed areas than for the ungrazed areas. Evidence indicated that livestock grazing in the sheep Creek riparian zone reduced initiation, which, inturn, increased runoff and soil loss but of minimal biological importance.
