Managing inundation risk requires prevention measures in close cooperation with Civil Protection Authorities. An evacuation trigger buffer is a pre-established boundary that circumscribes an area in such a way that when floodwaters (incl. waters, sediment, contaminated waters and pollution) coming from any direction cross the buffer, an evacuation is recommended. TRIBUTE software tool that will be delivered as a web service and as a mobile application, will provide the trigger buffers zones for a threatened site taking into consideration the current estimates of downpour hazards from satellites as well as its vulnerability and coping capacity. The service will have pan-European coverage and will be tested extensively in three pilot areas with different characteristics, including cross-border and multi-threat. TRIBUTE has rich training, dissemination and exploitation activities to promote the concept to the stakeholders.
