Abstract
HIDRALERTA is a forecast and early warning system for coastal and port regions capable of predicting emergency situations, as well as carrying out risk assessment. The system concentrates on evaluating wave overtopping and flooding scenarios. It uses offshore sea-wave and wind forecast data, as well as tide data, as input to determine wave overtopping at specific locations. The calculation of the mean overtopping discharge over a structure is made through artificial neural network tools and/or empirical formulae, which are able to define the spatial distribution of the flow behind the structure. The HIDRALERTA system is composed of four modules developed in Open Source Web Technology, mainly using the Python Language. The Warning System can be configured and adapted for specific scenarios. The system has been successfully tested for the Port and Bay of Praia da Vitória, Terceira Island, Azores, Portugal, and is now under development and being implemented at the ports of Madalena do Pico and S. Roque do Pico. This paper describes the work carried out to date on the system and its application to these two ports in the Pico Island, Azores.

The works related with the participation of M.I. Santos, P. Poseiro, M. Salvador and E. B. de Azevedo on the simulation of the application of HIDRALERTA System to the Port of Madalena, have been done under the framework of the ECOMARPORT (MAC/1.1b/081), with the financial support of 85% by the EU (FEDER, MAC 2014-2020), and 15% from the Regional Government of the Azores. F. V. Reis is responsible for the wave data and wave database used by the system. The works of C.J.E.M. Fortes, M.T. Reis, L.V. Pinheiro, J. Barateiro,V. Serrazina, A. Mendonça and N.
