Abstract: This paper describes an experimental study aiming at the investigation of the temporal evolution of propeller jet induced scours taking into account the effect of different propulsion systems. Time series of scour depths are presented which were obtained in experiments carried out with a stern scale model (1: 16) equipped with different propulsion systems, a Kaplan propeller in Kort nozzle and double rudder and a Wageningen B-series propeller with central rudder, respectively, and identical boundary conditions (underkeel clearance, number of revolutions, draft). Preliminary results are used to show the reproducibility of the experiments and to highlight the influence of the propulsion system on scour depth and geometry.
