Patent ID: 7395157

Claim:
A signaling system for automated location-dependent recognition of flood risks, comprising: a central unit including a multi-dimensional lookup table corresponding to a spatial high resolution grid of a specific geographic territory, flood risk factors being associated with the grid and indicating an average flood frequency and/or susceptibility to flooding within a grid cell, the flood risk factors being calculated based on flood zone data associated with the specific geographic territory, the flood zone data indicating in the specific geographic territory flood zones with defined return periods, distributed gauging stations configured to determine river discharge parameters within an area of multiple grid cells of the grid and to transmit the river discharge parameters over a network to the central unit, the river discharge parameters comprising at least values for a return period as a measure of intensity of flood events, the central unit comprising a correlation-module configured to generate an event-specific average probabilistic water depth value for a flood event based on the linked flood risk factors and the river discharge values, and to associate the probabilistic water depth value with the corresponding grid cell, and a cell arbitrator module acting on at least one grid-based composition module according to the average probabilistic water depth values.
