Sažetak
In this paper we present numerical simulations for the dam break flood wave propagation from Tribalj accumulation to Crikvenica (Croatia). The mathematical models we used were the one and the two-dimensional shallow water equations. They were solved with the well-balanced finite volume numerical schemes which additionally include special numerical treatment of the wetting/drying front boundary. These schemes were tested on CADAM test problems. The aim of this study was to assess potential damage in the cities of Tribalj and Crikvenica. Results of these simulations were used as the basis for urban planning and micro-zoning of the flood-risk areas. Several different dam break scenarios were considered, ranging from sudden dam disappearance to partial and dynamic breach formation. The research showed some advantages of numerical simulation over physical models.
