Abstract:

Development of a novel vertical diversion structure for spillways - Water engineering model tests for the Malter Dam

Due to the extreme flood event on the Elbe river in August 2002, there was damage and overloading of the spillway of the Malter Dam and massive flooding of the Rote Weißeritz. After this catastrophic Elbe flood event, the design discharges for the Malter Dam were significantly increased. The performance of the spillway was not sufficient for the new design discharges. The State Reservoir Administration of Saxony (LTV) has planned accordingly expanding the spillway. To restore the flood safety after DIN 19700-10, a concept was developed, which also includes the construction of a new, second spillway chute with additional new stilling basin, also due to the restrictions of the Monument protection to obtain the old spillway chute [1]. Both spillways are to be applied by a new division structure with a vertical flow separation. To ensure the performance the preliminary draft of the expansion of the spillway was reviewed and optimized in a physical model test in 1:25 scale at the Research Institute Water and Environment of the University of Siegen. With the hydraulic model test could the geometry of the vertical diversion structure be optimized so that with the implementation of the expansion of the spillway the flooding safety of Malter Dam can be restored.
