To access right information at the real time is crucial in the era of global networking, wireless broadband technology. Remote Sensing techniques are dominating to access timely damage assessment and gathered real information for relief planning during water related disaster. Floods are one of the natural disasters and pose serious threat to the normal life as well as process of development. During floods communication break downs and flood related information become hindered. Microwave Remote Sensing techniques provide timely and cost effective methodology for information communication and assessment of floods. Real time disaster assessment is handicapped by cloud cover/heavy rainfall. Microwave satellite data-Synthetic Aperture Radar (SAR) data have been to be found potential useful and functional for real assessment and management. This paper describes a flood delineation management from Bhuj Taluk of Kuchch District, Gujarat, India using microwave satellite ERS-1 SAR data with Path-scene /row nos.: 667-197. The flood disaster problem in the area is mainly due to hydrogeomorphological mismanagement i.e. deforested catchments area and the off-shore bar which chock the mouth of the river and obstruct the free flow surface water into the sea. When there is a heavy rainfall in the catchment area. It affects infrastructure and causes heavy loss of property and life or both. Microwave satellite data enable to demarcate preparedness program and mitigate the flood disaster situation. This data is highly useful for flood related disaster delineation, planning and management. It is also helpful during emergency operations plan in place to ensure the safety of our residents and initiate timely response of affected infrastructure.
