     the size of the ships which navigate in seas and inland waterways is increasing, mainly for economic reasons. a bigger ship needs a bigger thrust force to push it forward. large vessels with the powerful propellants usually equip a bow thruster for effective ship operation. subsequently a higher velocity propeller wash is induced. however these thrusters generate the strong current which may cause a local scour in front of a quay wall and affect its stability.  the loads on bottom protection differ, because of diversity in shipping and tidal motion. this paper reports the development of a new remotely operated vehicle (rov) based test facility and purpose-built by the authors to investigate unsteady dynamics of large marine thrusters on the profile of sedimentations near a quay wall of shahid rajaee harbor. laboratory experiment has been conducted to measure the local scour due to jet-like strong current which simulates, the strong current due to main and bow thrusters. the demands of stability required to guarantee a stable and safe bottom protection, this bottom protection is studied with soundings.
