Effects of Land Use Changes on Streamflow and Sediment Yield in Atibaia River Basin-SP, Brazil

The Soil and Water Assessment Tool (SWAT) is often used to evaluate the impacts of different land use scenarios on streamflow and sediment yield, but there is a need for some clear recommendations on how to select the parameter set that defines a given land use scenario and on what is the most appro...

This paper reviews the SWAT formulation to identify the parameters that depend on the land use, performs a sensitivity analysis to determine the ones with larger impacts on the model results and discusses ways to consider future land use conditions. The case study is the Atibaia river basin, with 2838 km(2)(Sao Paulo, Brazil). The parameters identified by sensitivity analysis with the largest impacts on streamflow and sediment yield were the initial curve number for moisture condition II (CN), maximum canopy storage for each land use (CANMX) and the cover and management factor (USLE_C). The identification and appropriate parameter change can provide real estimates of the magnitudes in the land use changes, which were verified in this study. Such information can be used as an instrument for proposing improvements in the basin's environmental quality and management.Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES)Univ Fed Sao Carlos, Grad Programin Urban Engn, BR-13565905 Sao Carlos, SP, BrazilUniv Lisbon, CERIS, Civil Engn Res & Inovat Sustainabil, Inst Super Tecn, P-1049001 Lisbon, PortugalSao Paulo State Univ, Grad Program Civil Engn, BR-15385000 Ilha Solteira, BrazilSao Paulo State Univ, Grad Program Civil Engn, BR-15385000 Ilha Solteira, BrazilMdpiUniversidade Federal de São Carlos (UFSCar)Univ LisbonUniversidade Estadual Paulista (Unesp)2020-12-10T20:07:02Z2020-12-10T20:07:02Z2020-06-01info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/article18http://dx.doi.org/10.3390/w12061711Water.
