The article presents the results of the analysis of flood situations in Ukraine. Two main types of flood protection measures are identified: situational and preventive. The main criterion for evaluating ther effectiveness is proposed. Two main alternatives of preventive flood protection measures using hydraulic structures have been identified, functionally opposite in nature of implementation. By combining them, the possibility of reducing the cost of constructing protective hydraulic structures has been proved. For optimal distribution of flood flows using a combined alternative of flood protection measures, a new method and two algorithms for its practical application have been proposed.
