They are activated 3-4 hours before maximum expected >= 110 cm.

Work began in 2003 and it’s expected to be completed by the end of 2021. Venice and its lagoon are on the northern Adriatic sea (immagine da Consorzio Venezia Nuova, www.istitutoveneto.it) Meteorological factors and storm surges at the origin of high water in Venice How EU projects are helping our job I-STORMS and STREAM are two integrated projects. These projects are inspired by a basin scale aproach. To increase the accuracy and reliability of sea storm forecasts is important to use the right scale, that is the adriatic-ionian area. This is only possible through the transnational cooperation. The I-STORMS project I-STORMS is a project co financed Common Understanding by the INTERREG Adrion programme and led by the City of Venice Increased I-STORMS aimed at enhancing knowledge innovative policies and develop joint strategies to safeguard the ADRION Increased skills II-STORMS Network and Permanent area from sea storm emergencies cooperationand Permanent table by: cooperation table -fostering transnational cooperation to by sharing knowledge, data and Increased awareness forecasts among involved countries -improving their capacities in terms of early warning and civil protection procedures Effective early warning systems -increasing accuracy and reliability of sea storm forecasts and thus be able to improve risk preparedness in the Adriatic-Ionian coastal areas The STREAM project Strategic development of flood management STREAM aims to increase the management capacity to promptly react to flood disasters in the Adriatic coastal area by developing: ● Efficient risk monitoring tools and early warning procedures ● flood risk management plans ● flood forecasting system Data sharing, flood cadastre, flood risk maps, exchange of practices and capacity building schemes for the emergency 4th November 1966 Services The project will also contribute to raise awareness about the flood risks in the areas involved and to people will learn how to behave in case of flood hazards.
