The invention relates to a method for removing deposits of sand and/or silt from the bottoms of bodies of water, optionally by means of hydropneumatic methods, in particular water injection, suction dredging or the like, in that, optionally prior to the hydropneumatic removal method being used, the sand/silt deposit to be removed is subjected to a force which reduces the viscosity of the deposit, the pressure on the deposit exerted by the devices serving to apply the force being variable. |
