Floods occur due to heavy rainfall leading to accumulation of excess water in human settlements. India often suffers from devastating monsoon floods, and a large chunk of its population lives in flood-prone areas. This causes a lot of property damage every year leading to huge amounts of economic loss, excluding the loss of lives. For the last 50 years, the total economic losses due to floods were more than 4.7 trillion due to building, crop, and other property damages. On the other hand, drought is one of the natural disasters which occurs due to climate variations and can be equally devastating. The conventional methods often fail to provide early clues to mitigate the devastating effects of floods and drought. In recent decades, remote sensing along with the Geographic Information System (GIS) has emerged as an efficient and cost-effective tool for mapping and monitoring floods and drought in near-real time. The tool has evolved from conventional optical monitoring to advanced radar remote sensing (SAR) data-based surveillance, operating in all-weather capability with higher spatial resolution. Temporal analysis using SAR imageries plays an important role in detecting the areas having higher hazard potential in advance. Flood and drought hazard maps are urgently required to help the decision-makers in managing and controlling relocation, mitigation, modernization, and protection measures in order to mitigate damages. This chapter aims to formulate effective strategies for determining the losses due to flood and drought for decision support in regional-level assessment and management. © 2022, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.
