The DEWETRA platform An advanced Early Warning System

“… in the Civil Protection world, now and immediately are not synonymous since to operate as we do it is necessary to have specific tools available, operational procedures and structures that are functioning on a 24 hour basis every day and, above all, decision making procedures capable of adopting” measures: ORGANIZED EFICCIENT TIMELY

integrate information already available (executed and implemented by multiple diverse entities) avoid duplications make outputs readily available in real time to key stakeholders prioritize needs make outputs interoperable into format that supports rapid and effective decision making effectively communicating the information to downstream users Need for a comprehensive platform to support decisions Information shared and organized !

Using technology… To make real-time data available for decision-making To support integration of systems (interoperability) To up-grade observation systems Sharing information to share knowledge … to improve capacity turning data into meaningful information effectively communicating the information to downstream users sharing technical skills and experiences sharing knowledge

Predictions & Early Warning Rapid response Disaster forecasting and nowcasting Monitoring & active disaster assessment The DEWETRA platform within the disasters management cycle

The aim of the Dewetra platform The Dewetra platform is a real-time event-based scenario builder, which allows the decision maker to take prevention actions and reduce the impacts of the forecasted event. Dewetra is not a mere forecasting tools, but also integrates information on vulnerability and exposure forecasters decision makers

R(t) = Real-time Risk Assessment & Prediction Quasi-static information Real-time information element at risks, hazard maps,... medium and short range weather forecasts, hydro-meteorological monitoring, impacts prediction (flood, soilslip), uncertainty estimation,… E x VE x Vx H(t)

Requirements and key features of the platform Facilitating multiple simultaneous users -Decision-makers & technical personnel Allowing multiple uses -Modeling and visualization of spatio-temporal information (elaborations) -Data managing and archiving (database) -Information dissemination to multiple stakeholders in realtime (presentations) Extendable and adaptable (architecture) Accessible 24/7

Software key features Open source Open Geospatial Consortium standards Interoperable Platform independent Browser independent

Risk bulletin preparation and distribution Daily risk bulletin Different risk level, in alert zones Different output formats: maps, large text, short textual (sms) Different communication channels: , fax, sms (cap)

Impacts report Synthetic description of impacts to organize response Standard template with georeferred information (easy to store) First indications for damage evaluation, linked to damage database (ex. Desinventar) Different communication channels: web, , sms
