The paper reports the results of the evaluation of SWAT (Soil and Water Assessment Tool) performance based on the recorded data at a small mountainous basin, mainly pasture, equipped some years ago in Eastern Sicily, in order to further extend model testing to semi-arid Mediterranean conditions. The model showed a good capability in simulating cumulated in the whole period of observation and yearly stream flows when the FAO Penman-Monteith equation was used to simulate the potential evapotranspiration. A high coefficient of determination and model efficiency were found in surface runoff estimation at monthly and daily scale. The model does not estimate well the different time scale base flows. A reasonable simulation of 25 event suspended sediment yields was found after a calibration/validation process carried out by modifying the USLE-C factor.

Abstract
The paper reports the results of the evaluation of SWAT (Soil and Water Assessment Tool) performance based on the recorded data at a small mountainous basin, mainly pasture, equipped some years ago in Eastern Sicily, in order to further extend model testing to semi-arid Mediterranean conditions. The model showed a good capability in simulating cumulated in the whole period of observation and yearly stream flows when the FAO Penman-Monteith equation was used to simulate the potential evapotranspiration. A high coefficient of determination and model efficiency were found in surface runoff estimation at monthly and daily scale. The model does not estimate well the different time scale base flows. A reasonable simulation of 25 event suspended sediment yields was found after a calibration/validation process carried out by modifying the USLE-C factor.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
