A support structure (2) is installed in or near a water (50). The support structure is holding a deltalike-wing (3) under an angle of incidence relative to an incoming flow (54), caused by at least a prevailing current in the water, thus generating a vortex (77). The action of the vortex is effective for the purpose(s) of maintaining the suspension of already suspended sediment within said current and/or of suspending sediment from a targeted first area (51) of the bottom of the water and/or of depositing suspended sediment within said current onto a targeted second area (52) of the bottom of the water. Thereby, the height distribution of the bottom of the water is controlled.
