The document outlines the Global Data Services initiative by Deltares, highlighting the importance of making global data accessible for various applications such as offshore windfarm operation, coastal management, and flood risk assessment. It details current capabilities, including models for hydrology and storm surge forecasting, and emphasizes ongoing development aimed at enhancing user access and functionality. The platform is in early beta stages, with plans for an official release and a call for user feedback to improve features and usability.

- 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 ?
- 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: 1979 - 2015 Type: Point and map data ?
- 12. 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
- 13. 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
