Real-Time Flood Forecasting and Warning System Sava River Basin
Development of Real-Time Flood Forecasting and Warning System for the Sava River Basin Klaas-Jan van Heeringen1, Hanneke Schuurmans2, Mihailo Anđelić3, Victor Simončić4, Imra Hodzic5, Sabina Hadziahmetovic5 ABSTRACT: Disastrous floods in May 2014 in Sava River basin resulted in 79 casualties and substantial economic damage in Croatia, Bosnia, Herzegovina, and Serbia. Assessments of the total damage in the area range up to 3.8 billion Euros. Distressing is the fact that besides flooding the Balkan region recently suffered from severe droughts as well. In order to be more resilient to flood and drought events, data and model output sharing is key. Better information will lead to better decisions. The Flood Forecasting and Warning System (Sava-FFWS) in which five countries jointly work together is at the forefront of transboundary cooperation. The FFWS, which is based on the well-known Delft-FEWS software, lends ample data and information enabling ultimately the decision makers to make right management decisions and implement operational measures to prevent and mitigate severe flood and drought situations on the basis of reliable forecasts of flows and discharges with a long lead time. The paper outlines key components of the Sava-FFWS illustrated with concrete application examples.
