This study attempts to simulate the daily discharge and sediment loss using a distributed model that combines surface and sub-surface runoffs in a small hilly watershed (< 1km(2)). The semi-quantitative model, Predict and Localize Erosion and Runoff (PLER), integrates the Manning-Strickler equation to simulate runoff and the Griffith University Erosion System Template equation to simulate soil detachment, sediment storage and soil loss based on a map resolution of 30m x 30m and over a daily time interval. By using a basic input data set and only two calibration coefficients based, respectively, on water velocity and soil detachment, the PLER model is easily applicable to different agricultural scenarios. The results indicate appropriate model performance and a high correlation between measured and predicted data with both Nash-Sutcliffe efficiency (Ef) and correlation coefficient (r(2)) having values>0.9. With the simple input data needs, PLER model is a useful tool for daily runoff and soil erosion modeling in small hilly watersheds in humid tropical areas. specialized surface runoff sub-surface runoff erosion hydrological modeling land use sloping land PCRaster Vietnam VIETNAM 062 068 020 28 6 2961-2974 2014 0885-6087 https://www.documentation.ird.fr/hor/fdi:010061870 10.1002/hyp.9860 0885-6087 [F B010061870] https://www.documentation.ird.fr/hor/fdi:010061870 https://www.documentation.ird.fr/intranet/publi/2014/04/010061870.pdf Accès réservé (Intranet de l'IRD) IRD - Base Horizon / Pleins textes 2014-04-29 2017-08-23 fdi:010061870 fre
