Flood Hazard Mapping in a Reservoir-regulated River Basin using Sentinel-1 imagery: The Case of Serres Basin.

Abstract : Flood is a natural disaster and causes loss of life and property destruction. Flood hazard Monitoring and Mapping is of great importance because it represents a significant contribution to risk management. The present study investigated the flood event occurred in 2014-2015 at Serres Basin, a reservoir-regulated river basin, aiming to understand its spatio-temporal dynamic of the flood hazard. Within the Strymon River basin, a transboundary river outflows to Kerkini Lake-reservoir which has the role of regulating water flow to downstream for irrigation purposes and flood protection. For this research, a dataset of Sentinel-1 SAR GRD images was collected and processed covering the period of October 2014 – October 2015. Based on SAR images binary water and non-water products were generated and interpreted. Satellite Earth Observation has proved to be an effective tool for hazard dynamic extension mapping and in combination with hydro-meteorological data can be a significant knowledge in flood disaster management.
