Water-Related Disasters (WRD), such as cyclones, floods, and droughts, account for 90% of natural disasters. Since the year 2000, over 5,300 WRD have been reported, with over 325,000 fatalities and an economic loss exceeding USD 1.7 trillion globally. Floods account for approximately 54 % of all WRD . Since the beginning of 2020, in South Asia alone, floods impacted over 17.5 million people, caused over 1000 deaths, and an economic loss of billions of dollars.A global survey of Flood Early Warning Systems (FEWS) conducted by the United Nations University Institute for Water Environment & Health (UNU-INWEH) shows that the majority of flood forecasting centers in flood-prone countries lack the ability to improve the spatial coverage of FEWS and generate historical inundation and flood risk maps. Developing these maps at the national level using conventional techniques is a costly exercise. In Canada, for example, it is expected to take one decade and USD 350 million to update national inundation maps. Theexisting inundation and flood risk maps in most developing countries are out-of-date and do not consider rapid urban development or the impacts of climate change.
UNU-INWEH has developed a Historical Flood Mapping tool that generates inundation maps for significant floods in the Global South from 1984 to the present using open Earth data. We are looking for an intern to assist in developing a Flood Risk Index. FRI will provide current flood risk estimates for cities, districts, and river basins. The FRI will be built using inundation maps generated by the HFMT and open-access datasets including population density, building footprint, elevation, GDP, land use, poverty maps, and meteorological and hydrological data.
Description of Responsibilities:
- Collect and synthesize open access socioeconomic datasets.
- Construct the flood risk index for selected cities.
- Validate the flood risk index for selected cities.
- Undertake additional tasks as assigned by the supervisor.
