Coastal risk forecast system

Runnup and overtopping are the two main sea wave originated events that threat coastal structures. These events may cause destruction of property and the environment, and endanger people. To build early warning forecast systems, we must take into account the consequence and risk characterization of the events in the affected area, and understand how these two types of spatial information integrate with sensor data sources and the risk determination methodology. In this paper we present the description and relationship between consequence and risk maps, their role on the risk calculation, and how the HIDRALERTA project integrates both aspects into its risk methodology. We present a case study for Praia da Vitoria port, in Azores Portugal.
