Presentation Transcript

  1. Using HPC to enable coastal waters observatories Marta Rodrigues, Anabela Oliveira, Ricardo Martins, João Rogeiro, Daniela Santos, André B. Fortunato, Alberto Azevedo 10th IberianGrid Conference, 2019 September 23-26, 2019

  2. Content • Background • HPC in UBEST • Operationalandscenariossimulations • UBEST Web Platform • Final Remarks

  3. Problem Estuaries provide several ecosystem services that may be threaten by human activities and climate change

  4. Challenges • How can scientists better understand the estuarine dynamics and the impacts of human pressures and climate change? • How to provide a channel to give the relevant information to scientists, decision-makers and the general public? • How to provide high resolution products faster?

  5. Waterobservatories • Support daily and long-term management actions to minimize the risks for public and ecosystems health: • Anticipate events of pollution and support the emergency response • Support common activities in the water bodies (management and leisure) • Continuous surveillance of coastal zones • Implementation and tuning of management plans

  6. Project UBEST • UBEST seeks to understand the changes on the biogeochemical buffering capacity of the estuaries and its susceptibility to future scenarios • Development of waterobservatories • Case studies:Tagus estuary andRia Formosa

  7. HPC in UBEST • HPC is used at two levels: • for high-resolution forecasts and scenarios simulations of the circulation and water quality dynamics in the two coastal systems • to provide computational power to process data and model results through predefined or user requests at the web-portal Numericalsimulations are performedwithmodel SCHISM: open source, communitymodel, fullyparallezedwith MPI

  8. Forecasts • Tagus estuaryand Ria Formosa • Daily forecasts of water levels and 3D currents, salinity, temperature and biogeochemical variables • ImplementedwithWaterInformationForecast Framework (WIFF) andOPENCoastS 3D service(http://opencoasts.lnec.pt/) • Need to providetimelyforecasts Chlorophyll a (mg/l) in the Tagus estuary

  9. Scenarios • Simulationofseveralscenarios of climate change (e.g. sea level rise) and anthropogenic pressures (e.g. wastewater discharges) -> high computational demands Minimum, meanandmaximumsalinity in the Tagus estuary for thereferencescenario

  10. UBEST Web Platform:Today Features: - Fetchtoday’s data andmodelinformation for eachobservatory - Filterobservatory data bychoosing a set ofdetailsonthis menu

  11. UBEST Plataform:Data Features: - Filter data fromrepositorybychoosing a set ofdetails - Data statistics - Viewandexport data

  12. UBEST Plataform:Forecasts Features: - Fetchmodelinformationfrommap server - Usercan selectvariableand time step to display - Probeonmodelresults - Data-modelcomparison

  13. Final Remarks • Water observatories: continuous surveillance • The use of HPC allows both the timely production of daily forecasts and the generation of long-term simulations for the scenarios • Web platform: access to observations, daily forecasts, future scenarios and indicators to support the daily and long-term management of coastal systems
