Indigenous Technical Knowledge has been the key rescuer of the fishers and common people of Dhemaji district of Assam, India from frequent floods in the region every year. They utilize the existing resources with a sustainable eco-friendly approach towards disaster management and exploration of fisheries resources and co-exist with the usual floods in the region. This study was conducted in the region through PRA after interviewing 110 fishers of three most flood-prone development blocks of the district with the help of an interview questionnaire.

During and shortly after a disaster data about the hazard and its consequences are scarce and not readily available. This research proposes a methodology that leverages social media content to support rapid inundation mapping, including inundation extent and water depth in case of floods. The use case in the city of Dresden for the June 2013 flood shows that social media may help to bridge the information gap when traditional data sources are lacking or are sparse.
