This article assesses the flood risk in the area of Cracow agglomeration. The most important courses having influence on the flood risk, were taken in to the consideration. The evaluation was based on the hydrological calculations and the hydrodynamic modeling of wave transformation in their river bed. The final risk assessment was a characterization of critical areas in which the most flood losses arise. It has been shown that the current security status in Cracow doesn’t assure an adequate level of security. Delay of outflow with use different form of small retention, reparation of drainage facilities, conservation of urban streams and building of dykes decreasing of flood risk into of Cracow agglomeration
