<p>The invention relates to a mould for creating specially-designed artificial roughness (18, 19) that is intended for the surface of structures and objects (10) which are submerged in a flow (12) and which are supported by, or buried in a soil that is liable to scour, such as bridge piers and piles, ducts and other elements. The artificial roughness, which is created during the casting of the structures, reduces both the intensity of the secondary flow at the leading edge and the intensity of the wake turbulence, thereby reducing the depth and volume of local scouring that can affect said structures.</p> |
