  1. Water Productivity using ET estimations from Remote Sensing and Hydrological Models Ann van Griensven & HichemSahli VrijeUniversiteitBrussel TowardanOpenResourcesUsingServices Torus project meeting, June 6-10, Ferrara, Italy

  2. HYDR: Large group of international researchers 3 full time professors / 3 part-time professors (10%) 3 Post-DoctoralResearchers ~20 PhDResearchers

  3. Where do we want to make a difference Hydrological modelling using field and remote sensing data • Model developments using open source software • WETSPA-python • SWAT • …

  4. Research in water across scales and disciplines Scale Services Urban drainage Brussels Flooding Nete basin, Belgium Ecosystems Bierbza, Poland Food security Ethiopia

  5. FP7: FP7: EnviroGRIDSBuilding Capacity for a Black Sea Catchment Observation and Assessment System supporting Sustainable Development 23 countries >160 million people>2.2 million km2

  7. Estimation of Agricultural Water Productivity Ecosystem Services Irrigation Industry Domestic Use Energy

  8. What is Water Productivity? “Crop yield per unit water” – cultivated areas “Ecosystem services per unit water” – natural areas

  9. From Efficiency to Water Productivity Crop yield

  10. ET can be derived from Temperature LOW ET - HIGH T° HIGH ET - LOW T° DoodeBemde Wetland - Land SurfaceTemperature DRY WET

  11. Development of remotesensingtechnologies Temperature

  12. Coupled Water-Energy Balance • Watershed mass-balance P = Q + E + DS/Dt • Surface energy-balance Rn = H + lvE + G + DS/Dt

  13. Original SWAT Improved spatial patternof water balance models Remote sensing ensemble SWAT-RS

  14. Tools • Remote Sensing (RS) and ENERGY BALANCE MODELS egLandsat images and SEBAL • Hydrological models: eg SWAT/WETSPA models • CROP MODELS: eg AQUACROP models • Modelling techniques: Sensitivity analysis, autocalibration, uncertainty analysis, data assimilation

  15. Collaborations ? • We welcome collaborations for work within this project for catchments in Asia  • AND • Cloud computing for processiong of remote sensing, hydrological models, sensitivity analysis, calibration, uncertainty, data assimiliation • AND • Workshops & Conferences in Brussels

  16. Conferences OpenWater conferences 2011, Delft, Netherlands 2013, Brussels, Belgium 2015, Addis Ababa, Ethiopia 2017, Rabat, Morocco iEMSs conference Toulouse, July 2016 Torus conference in Brussels 2017?
