Runoff and sediment yield modeling in a medium-size mediterranean watershed

摘要: The AnnAGNPS model was used to estimate runoff, peak discharge and sediment yield at the event scale in Carapelle watershed, a Mediterranean medium-size watershed (506 km2) located Apulia, Southern Italy. calibrated validated using five years of runoff data measured monitoring station Ordona – Ponte dei Sauri Bridge. A total 36 events output during period 2007-2011, comparison corresponding observations outlet. performed well predicting as testified by high values coefficients efficiency determination validation process. flows predictions were satisfactory especially for flow events; prediction capability good, even if slight over-estimation observed. Finally, evaluate effectiveness different Management practices (MPs) on (converting wheat forest, vegetated streams, crop rotation corn/soybean, no tillage). While maximum reduction achieved converting best compromises between soil conservation agriculture resulted be rotations.
