Selection of the Flood Management Solution of Karstic Field

Abstract Water resources management in karst areas is a very complex task, especially with regard to solving the problem of floods and protection against pollution. This is also true for flood protection of Vrgorsko polje, which is the subject of this paper. Complexity of water system and socio-economic characteristics in the broader area requires integral problem solving through analyses of several alternatives with different technical and technological features as well as different socio-economic and ecological impacts. In this paper, an elaborated integral approach to problem solving is presented as well as system analyses and the procedure of multicriteria selection of an optimum solution for karstic polje flood protection. The problem was successfully solved using the procedure with two basic steps. The first step analyzed possible basic solution concepts while the second analyzed engineering solutions in compliance with the adopted concepts. The results confirm the validity of this approach, which resulted in the elaboration of a flood protection project that was acceptable for all participants in the system.
