Experimental study in bed erosion induced by twin propeller in unconfined conditions

Scouring processes due to the navigation and manoeuvring of ships can generate stability problems to harbour’s structures. At the same time, the eroded material is settled in other areas, reducing the water level. Theoretical equations used are far from reality and only work for a single propeller....
