Sažetak
The Drava River levee was constructed in 1968. It protects the town of Otok Virje and approx. 450 ha of agricultural land, forests and other land from flooding. Its total length is 3711 meters. The large flood wave which moved from Austria through Slovenia to Croatia at the beginning of November 2012, created openings and caused a breach in Otok Virje – Brezje levee. As the maximum water level of the flood wave at places exceeded the embankment crown, the result was overtopping in the right levee longer than 1000 metres followed by breaching of embankment in length of 50 m. The flood hit 3 neighbouring towns, where 90 houses were flooded, and the total flooded area equalled approx. 6, 5 km2. This paper presents the methodology for risk assessment in reconstruction of Otok Virje – Brezje levee. For assessing the risks, the Analytic Network Process (ANP) was applied. The result is a list of risk priorities. Depending on the position a risk occupies in the list, appropriate resources will be used as the expected response to the risk. The network model resulted in a more stable decision-making process and greater adaptation to real life situations and to reasonable expectations.
