Satellite-derived Flood Mapping for Cambodia Technical Report: 2020
Cambodia is highly at risk of climate-related disasters, particularly flood and drought. Near real-time flood mapping could be a key component of a flood early warning and monitoring system.

Recent advances in Earth Observation (EO)-related technologies and products have made data increasingly more accessible and enables the development of near real-time flood monitoring applications. WFP have commissioned this report by the Asian Disaster Preparedness Center (ADPC) to explore how it can take advantage of the technologies for flood early warning and monitoring. To this end, the objectives of this report are to 1) analyze historical flood events in Cambodia; 2) produce and validate an historical flood dataset for Cambodia; 3) produce a flood hazard index; and 4) develop and validate Near Real-Time (NRT) water maps using Synthetic Aperture Radar (SAR) data.
