|Floods are part of a natural phenomenon which is regarded as a persistent hazard, causing negative socioeconomic impacts, i.e. significant damages to lives, livelihoods, and infrastructure. Therefore, flood management has gained more attention recently. Lack of time-effective and correct analysis of damage is major constraint for post disaster management. In many countries, Government have policy to give compensation rates for housing and agricultural loss but to implement this policy, there must be a reliable mechanism or approach to estimate damage. The government had highlighted the need to adopt remote sensing technology and tools as part of strategy in fighting against the menace of floods and many governments provides services too. However in the services, flood intensity considerations of depth, duration, velocity etc. have not been taken into account. In absence of flood depth and duration maps, optimal commitment of mitigation resources for micro level can’t be guaranteed. This hands on session will avail participants to estimate habitat and agricultural damage from polarimetric SAR data. We will be only be using SAR data for mapping, modelling and validation in freely available software and Google Earth Engine.
