Extreme precipitation and subsequent floods in tropical zones such as Puerto Rico have high potential of redistributing sediment through the river system, which can result in changes in river channel conveyance capacity. The changes in conveyance capacity would result in further flood hazard changes. We are also exploring the drivers of the flood hazard changes like average elevation, slope, and land use indices. This research will give us a better understanding of the causes of changing flood hazards, which can in turn help us make more accurate predictions of future floods.
