Original Abstract

The catastrophic flood in August 2002 endangered functional structures of dams with flow rates that significantly exceeded the values considered during their design. Particularly on the Znojmo Dam on the Thaya river, that was put into operation in the year 1966, the nominal discharge considered was Q = 355 m3.s-1. After the flood of 2002 the nominal discharge had to be increased to Q = 610 m3.s-1. Due to this change studies of the proposed reconstruction of the functional structures (block) were made. The aim was to increase the safety of the dam. The submitted paper presents results of the hydraulic research of these operational structures.
