https://doi.org/10.1007/978-3-8348-9202-7 order to set a particle in motion by the action of a flow of water, either the adhesive forces acting on adhering particles or the weight of lying particles must be overcome. Let us call v. the velocity of the flow of water capable of pulling particles lying on a horizontal surface along, and v. th
