1. Signaling system for automated location-dependent recognition of flood risks, flood states being transmitted to a central unit ( 20 ) and location-dependent flood probability values being determined, characterized in that the central unit ( 20 ) comprises a multi-dimensional lookup table ( 203 ) corresponding to a spatial high resolution grid ( 60 / 61 ) based on decentralized measurements of flood risk factors of a specific territory whereas the flood risk factors (P) being associated with the grid indicating the averaged flood frequency and/or susceptibility to flooding within a grid cell ( 60 / 61 ), in that the system comprises distributed gauging stations ( 5 / 30 / 31 / 32 ), whereas river discharge parameters (T) are measurable by the distributed gauging stations ( 5 / 30 / 31 / 32 ), within a grid cell ( 60 / 61 ) and transmitted over a network ( 50 ) to the central unit ( 20 ), the river discharge parameters comprising at least values for return period and/or intensity of measured events, in that the central unit ( 20 ) comprises a correlation-module ( 21 ) generating an event-specific averaged probabilistic water depth value (H) for an flood event based on the linked flood risk factors and the river discharge values, and associating the probabilistic water depth value (H) to the corresponding grid cell ( 60 / 61 ), and in that the system comprises an cell arbitrator module ( 22 ) accting on at least on grid-based composition module ( 23 ) according to the avaraged probabilistic water depth values (H).
