Rapid flood mapping by enhancing near real-time satellite imagery with real-time gauge and Tweeter data

PI: Cuizhen (Susan) Wang


Summary: Floods from high-category hurricanes, such as the 2015 Joaquin across SC and the 2017 Harvey in Houston, TX, are occurring more frequently and severely than ever. Rapid flood mapping is vital for local and federal authorities in preparedness and timely response of the disaster. This research aims to integrate field sensing (gauge data), social sensing (tweets) and remote sensing (satellite imagery) techniques to assist a spatially enhanced, rapid flood mapping in a near real-time phase. The expected framework of flood reconstruction model could seed a wide range of flood-related flood research activities.
