ABSTRACT
According to IPCC, South Asia is one of the most vulnerable and highly impacted regions of the world with India, being the fifth most vulnerable to climate change. Districts of Northeast India are on the forefront of being affected by recurring disasters of various nature and intensity. Rapid urbanisation and large-scale migration due to unequal distribution of resources and infrastructure has aggravated the causes for equality and inaccessibility of varying degrees. Far flung and border cities, districts of India have been focal points for unforeseen rapid development. Assam is one of the most flood-affected state in India. Topographically challenged, this region has been affected by climate change and frequent disasters in the past decades. Thus, making the local communities vulnerable and backward. Flooding in the areas of Upper Assam has caused massive loss to both life and property. Disaster Management through mapping would help in identification of critical areas as well as better planning of developmental activities. This paper uses a multisectoral approach in flood assessment and mapping at the sub-district level in the district of Dibrugarh, Assam through Flood Hazard Mapping. This paper focuses on the usage of geo-spatial tools through geomorphological, hydrological and embankment assessment for rapid assessment of disaster risk.
