Abstract: The engineering task of rock placement in coastal engineering and port construction is in practice done by dumping, involving the danger of rock size segregation. Horizontal spreading and segregation of the rock material is caused by horizontal deviation. Experimental surveys of vertical separation and horizontal spreading of bulk rock material were conducted at IWAWI and were accompanied by the development of two random-walk simulation schemes which are presented in this paper. The necessity of both physical experiments and numerical simulations for the proper treatment of a task of high physical complexity in engineering hydraulics is stressed.
