Sažetak
The selection of an appropriate coastal protection structure using multi-criteria analysis method AHP (Analytic Hierarchy Process) is presented by a case study of a beach reconstruction in the Kostanj Bay (north-western part of Croatia). The newly designed beach (about 300 m long) will be formed on the western part of the bay by additional filling of the natural rocky coastline with gravel and building reinforced concrete seawalls towards the sea. The beach will be protected by a submerged breakwater. Five different alternatives were analysed defined by a different design of the protective breakwater. The first alternative, without the submerged breakwater, was considered as the baseline. Additional four alternatives were examined based on four criteria and five sub-criteria, which considered technical, economic, social and environmental impacts. The sensitivity of the ranking for considered alternatives was analysed using five criteria importance scenarios.
