    Webinar aims

    Earth Observation (EO) data and services are vital tools for the water sector, supporting flood events, and wetland inventory status in rural and urban areas. EO provides valuable information (Flood extent, historical flood events etc.) with the aim to assist authorities to prepare the most effective actions to manage flood risk and develop plans to tackle disasters.
    The aim of this webinar is to present in detail how Earth Observation data with different spatial and temporal resolution can contribute to Flood risk, Water and Wetness management.  

     

    Webinar learning outcomes

    • To be informed of Cluster's Global Flood index, based on ERA5 precipitation data and Global Active Archive of Large Flood Events
    • To be informed of Cluster's Wetland & Water Monitoring Service with the use of high resolution (10-20m) data (Sentinel-1 & 2) identifying surface wetness and water bodies

     

    Webinar content

    • Introduction to the service
    • Introduction to Extreme Value Analysis
    • EO4SD-CR Precipitation Return Level products
    • EO4SD-CR Historical Rainfall Explorer
    • Showcase innovative water monitoring solutions based on state of the art satellite/EO technology
    • Specifically surface water and wetness variability over space and time will be adressed
    • Identification of short and medium-term trends by using a dense time series of high resolution EO data
