Abstract

Large scale hydraulic model tests were systematically performed for the probability, process and shape of floating debris jams at spillways as well as their effect on the discharge capacity. The test parameters were the characteristics of the floating debris and the hydraulic conditions of the approach flow. Concerning the jam probability it was shown in the tests that the characteristics of the floating debris are decisive: number, length and stiffness of the debris logs as well as number and length of their branches. In contrast the debris density and the hydraulic conditions of the approach flow are the most important parameters for the process and shape of debris jams and their effect on the discharge capacity. Finally, an example of an existing spillway is presented where similar knowledge was used for the design of a new debris rack.
