The EPHSTC land surface hydrological model is used here in a case study for the São Francisco River Basin (area 630.000 km²) located in Northeast Brazil. The model solves the surface fluxes using ISBA prognostic equations and a gravitational drainage, a vertical diffusion process. A mechanism for subgrid-scale surface runoff generation was added. Another feature implemented in this model is the lateral redistribution of the soil water. This work will be a first attempt of evaluating EPHSTC results in a Brazil catchment for a long time period - 2001 to 2014. The GLDAS model input surface parameters would be used. Validation will be performed by the model values of soil moisture with corresponding GDLAS soil moisture (0-10,10-40,40-60 cm) and latent and heat fluxes. The two time series will be compared by calculation of the coefficient of determination and root mean square error.
