El modelo swat en una cuenca peque？a de altas pendientes: Simulación de la producción de agua 1

a water yield simulation from swat model was evaluated in a sloped small watershed in venezuela. simulated daily values were compared with measured values obtained from a gauge channel by the use of difference and regression based indices. results indicated that swat overestimated the daily surface runoff values and underestimated the base flow values. in spite of that, total water yield for the whole experiment period was simulated accurately; it is therefore suggested that simultaneous fine-tunes of curve number values and underground water parameters should be done. it was concluded that a) transfer of swat calibration and validation may be difficult, because of the great amount of values that can be modified, and, consequently, it is convenient to have available sufficient information that allows proper adjustment of particular simulations and b) similarities in the cumulative simulated and measured values do not imply a proper model performance related with short or partial lapses, because error balances can occur for inconsistent value trends
