Abstract

This resource contains data and tools used in the paper “GeoFlood: large-scale flood inundation mapping based on high-resolution terrain analysis” submitted to Water Resources Research.
Simple and computationally efficient flood inundation mapping methods are needed to take advantage of increasingly available high-resolution topography data. In this work, we present a new approach, called GeoFlood, for flood inundation mapping using high-resolution topographic data. This approach combines GeoNet, an advanced method for high-resolution terrain data analysis, and the Height Above Nearest Drainage. GeoFlood can rapidly convert real-time forecasted river flow conditions to corresponding flood maps. A case study in central Texas demonstrated that the flood maps generated with our approach capture the majority of the inundated extent reported by detailed FEMA flood studies. Our results show that GeoFlood is a valuable solution for rapid inundation mapping.
