OPENCoastS

North Atlantic coastal circulation on-demand forecast

Summary

The OPENCoastS service assembles on-demand circulation forecast systems for selected areas in the Atlantic coast and keeps them running operationally for a period defined by the user. This service generates daily forecasts of water levels and vertically averaged velocities over the region of interest for 48 hours, based on numerical simulations of the relevant physical processes.

The OPENCoastS service is available in: https://opencoasts.ncg.ingrid.pt/.

The users manual is available here.

The use of the service is freely available, but a registration is needed at this site.

See:

- a hands-on demo on the OPENCoastS platform.

- the 2018 IMUM presentation on the platform.

During the IMUM 2018 workshop, a hands-on tutorial will be given. In november 2018 (date to be announced) an e-tutorial will be given, accessible without fee either at LNEC's premises or through a link to be announced later.

OVERVIEW

Forecast systems are fundamental components of emergency response and routine management of coastal regions. They provide coastal managers and all entities that have responsibilities on the coast with accurate and timely predictions on water conditions (e.g., water levels and velocities, wave characteristics), supporting multiple uses such as navigation, water monitoring, port operations, dredging works and construction activities on the coast. Simultaneously, they are an indispensable tool for emergency agents and civil protection authorities by anticipating natural disasters (e.g., floods, storm surges and algae blooms), predicting the impacts of anthropogenic accidents in the coast (e.g. oil and chemical spills) and helping in search and rescue operations. For over 10 years LNEC has been developing and deploying a forecast framework, denoted WIFF – Water Information Forecast Framework, applicable from the ocean to the hydrographic basin, including the urban interface.

However, the development of forecast systems requires not only a strong knowledge of coastal processes but also of information technology, along with access to significant computational and storage resources. The setup and maintenance of these systems constitutes therefore a major difficulty for many coastal research groups. Before the EOSC-Hub H2020 project, services for generic deployment of forecast frameworks at user-specified locations were not yet available.

To overcome this limitation, LNEC, LIP, CNRS/LR and UC have developed the OPENCoastS service which builds on-demand circulation forecast systems for user-selected sections of the North Atlantic coast and maintain them running operationally for the timeframe defined by the user. This daily service generates forecasts of water levels and 2D velocities (and wave parameters in the near future) over the spatial region of interest for periods of 48 hours, based on numerical simulations of all relevant physical processes. Presently, all forecasts are made with the model SCHISM (http://ccrm.vims.edu/schismweb/).

CONCEPT AND ARQUITECTURE
Goals and requirements for the forecast on-demand service include:

- it should be accessible through a simple Web interface with both users manual and a hands-on demo available;

- it should be flexible, in the choice of the model, forcings and domain of application;

- it should be modular and allow fast updates on models, integration of new forcings. It should also allow fast replication of a on-going deployment to new parametrizations or new choices of forcings, without building form scratch;

- it should provide authomatic comparison with available on-line data on the domain of choice, to provide quality control and user trust on the simulations

- it should provide the possibility to share deployment results in an open way or to a restricted group of users to promote open data and joint research by several groups, and joint decision making by management authorities

The Architectureof the service, including both frontend and backend is shown here:

Presently, all forecasts in OPENCoastS are made with the model SCHISM (http://ccrm.vims.edu/schismweb/). SCHISM is an open-source community-supported
modelling system based on unstructured grids, designed for the seamless simulation of 3D baroclinic circulation across lake/river/estuary/shelf/ocean scales (Zhang et al., 2016).

OPENCoastS allows for a suite of forcing options and provides access to the forecast results through a simple viewer that comprises maps of forecasted variables and charts of model data comparison at monitoring stations as well as time series of model results at virtual sensors (e.g. locations selected by the user):

OPENCoastS is supported by LNEC's real time forecast framework WIFF - Water Information Forecast Framework (http://ariel.lnec.pt). WIFF started to be developed at LNEC in 2007 for the 2D circulation at the Aveiro lagoon  (Oliveira et al., 2010). It was expanded to short wave propagation in the Northe Atlantic and Portuguese coasts in 2010  (Ribeiro et al., 2010) and to coupled wave-current circulation in 2016  (Fortunato et al., 2017) as well as 3D baroclinic predictions (Rodrigues et al., 2016). It also includes the circulation and water quality due to urban discharges (David et al. 2015).

OPENCoastS is supported by the EGI computational resources, through project H2020 EOSC-Hub, being available as one of its thematic services (https://www.eosc-hub.eu/catalogue/OPENCoastS)
