DSD-INT 2019 - Global Data Services and Analysis Frameworks - Twigt

  1. 1. Global Data Services and Analysis Frameworks Dare to share global data Delft3D User Days 2019 Daniel Twigt & Mark Hegnauer
  2. 2. Global Data Services Making global data available on a digital platform for everyone 2
  3. 3. Global Data Services Making global data available on a digital platform for everyone 3
  4. 4. Global Data Services Why? 4
  5. 5. Why focus on global data services? Towards services ‘Global’ sets an ambition Market for global information

  8. 8. 8 Offshore As a windfarm operator, I want to assess metocean conditions at my windfarm, to assess workability conditions. Workability conditions Design conditions FoundationMaintenanceTopics Wind & wave climates Water level statistics Future sea level rise Future waves & wind Extreme waves Operational currents Regular bathymetries Example: MetOcean database. Historic wind and wave climates + statistics based on data of global (external) models (ERA-Interim, ERA5, CFSR) Period: 1979 - 2015 Type: Point and map data Data ?
  9. 9. Coastal management Shoreline positions Trends in shoreline change Storm ImpactTopics As a coastal manager, I want to assess the state of my coast every year & after storms, to decide for mitigating measures. Wind & wave climates Water level statistics Extreme waves Frequent bathymetries Future sea level rise Future waves & wind Operational currents Regular bathymetries Historic shorelines On-the-fly shorelines changesOperational waves Data Operational water levels (tide & surge) Operational Discharge Example: Shoreline monitor. Historic shoreline erosion and accretion Period: 1979 - 2015 Type: Point and map data ?
  10. 10. Flooding Flood hazards Flood impact Future floods As a crisis response manager, I want to assess the flood risk due to the typhoon approaching the Philippines, to warn the people in time. Topics Wind & wave climates Water level statistics Future sea level rise Future waves & wind Extreme wavesOperational currents Regular bathymetries Operational waves Operational water levels (tide & surge) ? Operational Discharge Data Example: GLOSSIS (GTSM) and GLOFFIS
  11. 11. Global Tide and Surge Model v3.0 • 2D barotropic model • Unstructured global grid (25 km ocean - 2.5km coastal/1.25km EU) • Bathymetry: • EMODnet (250m) for EU • Bedmap2 below lat 60S • GEBCO 2014 bathymetry(~1km) • TGF driven, no assimilation • Two physical processes that are not negligible at a global scale: • Self attraction and loading (SAL) • Tidal dissipation through generation of internal tides Runtimes in 8 cores ~3.6hour/week
  12. 12. GLOSSIS: real-time water level and storm-surge forecasts at world-wide scale • Real-time, medium-term forecasts • Historical timeseries • anywhere • Ingredients: • Deltares expertise: hydrodynamics, storm surge, wave, bathemetry • Computational engine: Delft3D FM based GTSM model • Forecasting platform: Delft-FEWS • Storage: Deltares OpenArchive
  13. 13. GLOFFIS: real-time hydrological forecasts at world-wide scale • Medium-term and seasonal fluvial flow forecasts • Historical timeseries • anywhere • Ingredients: • Deltares expertise: hydrology, WRM, forecasting • Computational engine: Delft3D FM based models: • D-Hydrology (wflow) • D-Flow FM (1D) • Forecasting platform: Delft-FEWS • Storage: Deltares OpenArchive
  14. 14. Recent developments: Global wflow • Setup at 1x1 km2 • Using globally available base data: • MERIT elevation data • Soilgrids soil data • Globcover / Corine landcover data • With minimal calibration
  15. 15. Recent developments: Global wflow • Setup at 1x1 km2 • Using globally available base data: • MERIT elevation data • Soilgrids soil data • Globcover / Corine landcover data • With minimal calibration Samaniego, Luis, Rohini Kumar, and Sabine Attinger.

  16. 16. Recent developments: Global wflow • Setup at 1x1 km2 • Using globally available base data: • MERIT elevation data • Soilgrids soil data • Globcover / Corine landcover data • With minimal calibration
  17. 17. Recent developments: Global wflow Linked to other modules D-Hydrology & D-Flow FMD-Hydrology & D-Water Quality D-Hydrology & D-Soil Erosion
  18. 18. Where are we now with the Global Data Services • Still under development (early beta stage at present) • Available on the Deltares network (now) • Available for external beta-testers Q1 2020 (sign up) • Official release end of Q1 2020
  19. 19. Where are we now and next steps Develop a platform that has: • Easy access to (global) data • Enables quick setup of model & tools • Includes a Model Analysis Framework • To support Water Resources Management & Planning
  20. 20. Your feedback is appreciated • General look and feel • Which additional features would be useful • Are the available data sources useful • What should be changed to make it (more) useful • What kind of opportunities do you see?
  21. 21. Thank you!
