    About United Nations University

    For the past four decades, UNU has been a go-to think tank for impartial research on the pressing global problems of human survival, conflict prevention, development, and welfare. With more than 400 researchers in 13 countries, UNU’s work spans the full breadth of the 17 Sustainable Development Goals, generating policy-relevant knowledge to effect positive global change. UNU maintains more than 200 collaborations with UN agencies and leading universities and research institutions across the globe.

    United Nations University Institute for Water, Environment and Health (UNU-INWEH)

    The United Nations University Institute for Water, Environment and Health (http://inweh.unu.edu/) is a member of the UNU family of organisations. Its vision is a world free of water problems where sustainable human development and environmental health and security are assured for all. Its mission is to help resolve pressing water challenges that are of concern to the United Nations, its Member States, and their people. UNU-INWEH pursues its mission through critical analysis and synthesis of existing bodies of scientific discovery, targeted research that identifies emerging policy issues, application of on-the-ground scalable science-based solutions to water issues, and global outreach. UNU-INWEH is the only entirely-water focused institute within the UNU System, and the only entirely water-related UN entity in Canada. UNU-INWEH is supported by the Government of Canada and hosted by McMaster University.

    UNU-INWEH works on four broadly defined, interconnected thematic areas: i) accelerating the implementation of water-related SDGs; ii) activating a technology revolution for water security in the Global South; iii) advancing gender equality for effective water management; and iv) managing water- and climate-related risks for improved water security. For more information, see the UNU-INWEH-Strategic-Plan. The institute focuses primarily on global water issues and their implications for developing countries.

    Project description

    UNU-INWEH is developing a flood mapping and future flood risk prediction tool. This tool consists of two modules; a flood mapping module that addresses the data gap of historical flood maps, and a flood risk predicting module, which addresses the issue of possible risk in the future.

    The historical flood mapping module uses a water classification algorithm (Modified Normalized Difference Water Index) applied to ‘stacks’ of historical Landsat and Sentinel 2 satellite imagery to reveal patterns of inundation over space and time across the landscapes. The prototype of the tool is ready, which uses Landsat data to identify water patterns.

    The second module will use AI models to predict the future flood risk for a given area. The AI models will be trained using the historical flood maps from the first module, and open temporal datasets including land use land cover, population, infrastructure, precipitation, temperature, and sex and age disaggregated socio-economic data. This module will help identify the most flood-risk areas for the future.

    We are looking for an intern who can work remotely to assist in the development of the first module of the tool by integrating the Harmonized Landsat Sentinel-2 data.


    Responsibilities of the position include:

    • integrate the harmonized Landsat Sentinel-2 data
    • test the integration against recent flood events (validation data is available)
    • optimise the HFMT system flow where possible
    • undertake additional tasks as assigned by the supervisor

    Learning objective

    Develop interns’ research knowledge and capabilities, including the ability to use harmonised Landsat Sentinel-2 data in Google Earth Engine and implement surface water mapping algorithms.
