Hydraulic fill - Wikipedia

Hydraulic fill is a means of selectively emplacing soil or other materials using a stream of water. It is also a term used to describe the materials thus emplaced. Gravity, coupled with velocity control, is used to effect the selected deposition of the material.. Borrow pits containing suitable material are accessible at an elevation such that the earth can be sluiced to the fill after being ...
