Content § Background § HPC in UBEST § Operational and scenarios simulations § UBEST Web Platform § Final Remarks 2

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

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? 4

Water observatories § 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 5

Project UBEST § UBEST seeks to understand the changes on the biogeochemical buffering capacity of the estuaries and its susceptibility to future scenarios § Development of water observatories § Case studies: Tagus estuary and Ria Formosa 8

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 Numerical simulations are performed with model SCHISM: open source, community model, fully parallezed with MPI 10

Forecasts § Tagus estuary and Ria Formosa § Daily forecasts of water levels and 3 D currents, salinity, temperature and biogeochemical variables § Implemented with Water Information Forecast Framework (WIFF) and OPENCoast. S 3 D service (http: //opencoasts. lnec. pt/) Chlorophyll a (mg/l) in the Tagus estuary § Need to provide timely forecasts 12

Scenarios § Simulation of several scenarios of climate change (e. g. sea level rise) and anthropogenic pressures (e. g. wastewater discharges) -> high computational demands Minimum, mean and maximum salinity in the Tagus estuary for the reference scenario 13

UBEST Web Platform: Today Features: - Fetch today’s data and model information for each observatory - Filter observatory data by choosing a set of details on this menu 16

UBEST Plataform : Data Features: - Filter data from repository by choosing a set of details - Data statistics - View and export data 17

UBEST Plataform: Forecasts Features: - Fetch model information from map server - User can select variable and time step to display - Probe on model results - Data-model comparison 18

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 19
