Völker, G. Meng, J.H. Corporate name TU Delft Date 2004-01-01 Abstract Research at IWAWI of TU Berlin focuses on rock placement in coastal engineering and port construction. During research work it was found that objective and descriptive shape classification of rocks was needed. The introduced method utilizes three independent parameters: size referred to by volume, shape according to Zingg and roundness according to Diepenbroek or by the degree of shape deviation of the rocks equivalent ellipsoid of inertia. This classification is visualized in a three dimensional parameter space. Underwater falling properties of natural rocks were object of a systematic experimental examination. These properties are associated with the parameter space. The digital visualization of the examined rocks and the experimental results on properties and motion are presented in a PC-based interactive information system RockDataBase. The user can query information on any rock by using RockDataBase as a modern form of comparison table to acquire shape properties, hydraulic properties and a visualization of its under water motion.
