Abstract

Effect of the hydrograph characteristics on the flood propagation due to dam break is studied by means of a distorted physical model of Ürkmez Dam, built in the scope of the TÜBİTAK 110M240 project, in open area of Hydraulics Laboratory of Dokuz Eylül University. The physical model has a horizontal scale of 1/150 and a vertical scale of 1/30 and it contains the reservoir and the downstream part of the dam until the sea. The Ürkmez dam was chosen since it has reasonable dimensions and it’s located close to Ürkmez village. The dam break was simulated by lifting the trapezoidal or triangular parts of the dam body to reflect the partial dam break, and also by lifting the gate suddenly in order to reflect the sudden failure. The water depths were measured by using e+ WATER L (level) sensors. The velocities were determined by Ultrasonic Velocity Profiler (UVP) transducers. The propagation of the flood wave was recorded by a HD camera. In this paper, the design and construction of the distorted physical model and the measurement method are outlined. Some experimental findings corresponding to different hydrographs are presented and compared.
