Multi-criteria Optimization Methods in Water Management

Today, beside the economical aspect that was the most important criterion until 30-years ago, the protection of environment (and water as a part of it) and the social impact of water management projects have a very important role in decision-making process in water management. The complexity of problems in water management is the result of complex and numerous needs, goals and different measure criteria for the evaluation of those solutions. This complexity leads to developing multi-criteria optimization methods that allow evaluating solutions and choosing the optimal among them on the base of different measure criteria. This paper deals with the use of multi-criteria optimization methods PROMETHEE, ELECTRE and AHP, on which computer softwares PROMCALC & GAIA V.3.2., ELECTRE TRI 2.0 a and EXPERT CHOICE Pro 9.5. are based, for choosing the best reservoir configuration for irrigation of agricultural areas in western Istra in Croatia. The choice is made among twelve generated solutions (alternatives), by evaluating them on the base of ten different measure criteria according to a previously defined testing plan. In the paper is concluded that chosen multi-criteria optimization methods are, using critically evaluated input data, appropriate and useful for decision making (choice of optimal solution) in water management problems and that further research and study on improving the process of solving problems in water management should be done in the direction of better defining criteria and measures, complex generated solutions and improving and developing new multi-criteria optimization methods.
