Management of water resources in this watershed has become a challenging issue. Conformity of modeling processes and result to mimic the existing hydrological processes is still in question. This study aims to analyze the sensitive parameters of the Soil & Water Assessment Tool (SWAT) model on the watershed. Hydrological processes are observed both monthly and annually. Sensitivity analysis using the SWAT-CUP tool show 18 sensitive parameters. 9 parameters have more than a 50% sensitivity level. 4 are correlated to the soil layer’s runoff generation and water movement. Then, 8 parameters correlated to baseflow calculation. Simulation results illustrate the strong effect of climate change (especially rainfall) on water yield and sedimentation. 2023 artículo científico 0101-9759 https://www.redalyc.org/articulo.oa?id=695375062012 https://www.redalyc.org/journal/6953/695375062012/ https://www.redalyc.org/journal/6953/695375062012/html/ https://www.redalyc.org/journal/6953/695375062012/695375062012.epub https://www.redalyc.org/journal/6953/695375062012/movil 10.11137/1982-3908_2023_46_48173 en http://www.redalyc.org/revista.oa?id=6953 Anuário do Instituto de Geociências application/pdf Universidade Federal do Rio de Janeiro Anuário do Instituto de Geociências (Brasil) Vol.46 |
