With an arrangement for determining the penetration depth ( 10 ) when putting in place supporting elements ( 2 ) into a water bed ( 5 ), according to the invention, there is provided a pressure sensor ( 7 ) for measuring the water pressure which is fastenable to the supporting element ( 2 ) or to a device ( 1 ) connected to the supporting element ( 2 ). The readings ( 11 ) supplied by the pressure sensor ( 7 ) are transmitted via a signal lead ( 15 ) to an evaluation unit ( 16 ) which determines the penetration depth ( 10 ) of the supporting element ( 2 ) from the reading differences which occur during the sinking of the pressure sensor ( 7 ) on penetration of the supporting element ( 2 ) into the water bed ( 5 ).
