Originální abstrakt

Many dams and waterworks had been built in Czech Republic during 1950s and 1960s. The one of them is the Znojmo Dam. It is an earth dam with combined spillway block. The nominal discharge of Q = 355 m3.s-1 was considered to design of the safety spillway. Extreme flood events occurred in Czech Republic in 1997 and 2002 evoked questions relating to the safety of dams. The nominal discharge of the Znojmo Dam safety spillway was enhanced up to Q = 610 m3.s-1. Therefore, the decision of reconstruction of the Znojmo dam spillway block was made. The following modifications were proposed: to sink the existing spillway crest, to replace the existing flap gates with tainter gates with flaps, installation of breakwater on the dam crest, and necessary modifications of the stilling basin. With regard to the importance of the dam and the volume of the planned reconstruction, assessment on a hydraulic model was necessary. This paper summarizes the results of the hydraulic research and its practical application on the processing reconstruction of the Znojmo Dam. It also describes some differences between the modeled situations and reality.
