Soil and Water Assessment Tool (SWAT, version 2009) model integrated with Geographic Information System (ArcGIS, version 10.0) were used to simulate the discharge and sediment concentration of Wadi Harraza's basin for the period from 2004 to 2009. Model calibration and validation were performed for monthly time periods using Sequential Uncertainty Fitting 2 (SUFI-2, version 2) within SWAT-CUP. Our calibration and validation outputs for monthly simulation showed a good model performance for discharges. Thus the evolution of the average total annual sediment in the Wadi Harraza's basin which will be deposited in the Wadi Cheliff, is estimated at 54.24 t ha-1. specialized MODELE HYDROLOGIQUE SEDIMENTATION FLUVIATILE TRANSPORT SOLIDE EROSION HYDRIQUE EVALUATION ETALONNAGE CALIBRAGE BASSIN VERSANT COURS D'EAU MODELE SWAT VALIDATION 2004 2009 ALGERIE 062MECEAU04 064SEDIM 068EROSOL 32 79-88 multigr. 2018 https://www.documentation.ird.fr/hor/fdi:010078602 10.1016/j.wsj.2017.12.004 [F B010078602] https://www.documentation.ird.fr/hor/fdi:010078602 https://horizon.documentation.ird.fr/exl-doc/pleins_textes/divers20-07/010078602.pdf IRD - Base Horizon / Pleins textes 2020-06-15 2023-07-11 fdi:010078602 fre
