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

  1. 1. Global Data Services and Analysis Frameworks Dare to share global data Delft3D User Days 2019 Arjen Luijendijk
  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
  6. 6. Global Data Services Incredible content Develop incredible content such that our members will not be shy to share the content Consulting Allow members to gain access to our consulting expertise Paid subscribers This is optional, not sure yet if this applicable for all data/services. Ideally everything should be free for everyone but we need to cover at least our OPEX Free services Capture potential members with free-mium model Data as a Service Great data Give access to incredible data such that our clients will and can re-use the data for their own benefit Information as a Service Valuable information Give access to valuable information such that our clients will and can re-use the info for their own benefit Platform as a Service Collaboration and impact Allow members and clients to gain access to our data, information and expertise to collaborate with us and the community. Glossis Global Storm Surge information system Gloffis Global Flood Forecast iinformation system Aquamonitor Monitoring surface water changes from space. Shoreline monitor Long-term Shoreline Changes GEBCO Satellite-derived bathymetry MetOcean Database Accurate and detailed database of operational and extreme metocean parameters for the offshore waters 6

  9. 9. 9 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 ?
  10. 10. 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: 1984 - 2017 Type: Point and map data ?
  11. 11. 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
  12. 12. 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 Runtimes in 8 cores ~3.6hour/week
  13. 13. 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
  14. 14. 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
  15. 15. 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
  16. 16. 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 • Upcoming data sets: • Water levels & currents for RCP4.5 and RCP8.5 • Extreme precipitation due to global warming • Urbanization and Human Settlements • …
  17. 17. 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?
  18. 18. Thank you!
