Description :
The aim of this study is to characterize, model and analyze the temporal variability of hydrological processes in the Rio Cobre watershed, Jamaica using the Soil and Water Assessment Tool (SWAT). Determination of the temporal hydrological water balance and the spatial distribution of hydrological processes in the Rio Cobre watershed are discussed. The ability of a watershed model to accurately predict the hydrological processes is evaluated through parameter sensitivity analysis, model calibration and validation. Sequential Uncertainty Fitting (SUFI-2) calibration and uncertainty analysis methods were used for the set-up of the SWAT model. The model evaluation statistics for streamflow prediction show that there is a good agreement between the measured and simulated flows. The spatiotemporal distribution of hydrological processes was determined. It is highlighted that 52% of rainfall is lost by evapotranspiration and that the groundwater contributes 42% to the water yield.
