Abstract

Frequent flooding is a common occurrence in the Mesoamerica region, causing both death and destruction. With a flood forecasting system in place, the safety and security of both people and property in this region can be greatly improved. The HFFS will consist of meteorological and hydrological models coupled to create flood inundation web-maps. Due to the poor availability of observed data in the region, the precipitation data will be derived from satellite images, and combined with additional GIS data to determine watershed characteristics such as land use distribution. A multivariate analysis of key variables will be used to group the watersheds and delineate regions of similar hydrometeorological performance. The obtained regionalization allows the use of regional parameters in the ungauged watersheds. The HFFS distinctiveness is its applicability not only in the Mesoamerican region, but also in other floodprone areas in the world with limited access to relevant data.
