Executive Summary :

Flood events cause substantial damage to urban and rural areas. Monitoring water extent during large-scale flooding is crucial in order to identify the area affected and to evaluate damage. During such events, spatial assessment of flood water may be derived from satellite or air borne sensing platforms. Meanwhile, an increasing availability of smartphones is leading to documentation of flood events directly by individuals, within formation shared in real-time using social media. Topographic data, can be used to determine where floodwater can accumulate. Therefore, in this project, it is proposed to integrate information derived from multiple sources to aid in the estimation of flood inundation extent and identifying hot spots.
