ABSTRACT
Floods are the most frequent types of natural disaster. Assam with its vast network of rivers is prone to floods and soil erosion which has a negative impact on overall development of the state. The flood and erosion problem of Assam is different from the other states, if we consider the extent and duration of flooding and magnitude of erosion, which makes floods , the most acute and unique in the country. So,satellite-based flood assessment for extent and severity is a very crucial input before, during, and after a flood event has occurred. Though optical remote sensing data has been widely used for flood hazard mapping in the recent time Synthetic Aperture Radar (SAR) data is preferred for detecting inundated areas and providing reliable information during a flood event due to its capability to operate in all weather and day/night time. The present study is an attempt to use SAR data for showing the flood-prone areas of Jorhat District during the last five consecutive years and its impact on land-use and land cover change. Google Earth Engine (GEE) was used for implementing for processing Sentinel—1 SAR data and the flood areas identification. Flood events are common in the study area during the monsoon season due to high rainfall and its close proximity to the Brahmaputra River. Dual polarized (VV and VH) Sentinel-1 SAR images obtained for the entire monsoon period during the last five years were used to create inundation maps of the study area. The geospatial study of the flood provides the valuable information for flood privation and mitigation, disaster planning in the Jorhat District of Assam. Observations from Sentinel-1 SAR data using GEE can act as a powerful tool for mapping flood inundation areas at the time of disaster, and enhance existing efforts towards saving lives and livelihoods of communities.
