This paper deals with evaluating the impact of dry reservoirs on flood events. The system of dry reservoirs could create an effective part of integrated flood protection.

The system of four uncontrolled dry reservoirs was theoretically implemented to the headwater part of the Rolava River basin in the Ore Mountains. The main aim was to evaluate the potential impact of the dry reservoirs on peak discharge decrease during two known rainfall events in September 2007 and in August 2006 and four theoretical scenarios 10, 20, 50 and 100-year return period of 1-day precipitation.

Rainfall-runoff modelling was carried out by means of the model HEC-HMS (Hydrologic Engineering Center Hydrologic Modeling System) with satisfactory agreement in the calibration and verification process.
