Breakwaters

The breakwaters, also called breakwaters or breakwaters, are transversal works that advance from the existing shore to the new shore line, to reduce the excessive width of the bed, causing sedimentation of the area limited by them and generating a displacement in the axis of the channel. of a river; They channel, correct or control the natural course of water. These works have the purpose of directing the flow of the current, preventing the forces of the waters from impacting the banks. They are generally used in groups to create sedimentation zones between them and consequently the disposal of solid material, thus reconstructing margins already affected by erosion. They are structures that are attached to the bank and interposed to the current, which allows the current to be diverted and moved away from the shore and prevent it from dragging the particles that form it. The breakwaters are built within the channel with rock blocks of considerable size, or with prefabricated concrete elements (cubes, parallelepipeds, idols and tetrapods or quadripods) that are placed in the water, in rivers, streams or near the sea coast.
