Global model MOHYSE, a new tool to assess the effect of hydro-meteorological phenomena in the tropics

In this research the adaptation to tropical conditions of a Canadian global hydrological model (GHM) called MOHYSE was performed, and the efficiency of its hydrological response was evaluated. A hydrological modeling study over central watersheds of the Gulf of Mexico was performed and various indices were calculated to evaluate the GHM response. Additionally, the GHM was compared with a semi-distributed hydrological model (SDHM) to determine which of the models was closest to the hydrograph observed in the study area. The results indicate that both models adequately fit to tropical conditions; however the MOHYSE obtained better results in the statistical analysis compared to the SDHM, mainly with the Nash-Sutcliffe efficiency coefficient. Likewise, these results have direct application in the analysis of flood risk areas and could serve as an useful tool for policy makers.
