Beach Erosion Control Structures

Hard armor systems protect the coast from erosion.

Beach erosion control structures. Scour and erosion protection protecting against loss of soil around underwater structures our products combine ballast with filtration to withstand the strong shear forces involved with underwater foundation elements such as piles quay walls and bridge abutments. It is usually made of large boulders but it can be made of concrete steel or wood. Breakwater tubes are commonly used for long demanding or extended shoreline support. Scour is the result of bottom shear stress induced by water velocity.

Erosion control mats are sometimes an option for areas around shorelines or beaches. Hard armor structures are designed to. Bulkheads can be constructed by concrete steel or timber. Groins are another example of a hard shoreline structure designed as so called permanent solution to beach erosion.

It is designed to interrupt and trap the longshore flow of sand. Types of coastal protection structures 1. These artificial structures are the traditional coastal erosion solution. Trap and retain sand.

This large coastal protection structures can be built using different types of construction materials such. The basic design parameters for breakwaters functioning as erosion control devices include their height length distance offshore and spacing in the case of multiple breakwaters structure porosity and beach sand grain size these parameters in additi on to the resulting alteration in breaking wave height and wave angle will determine whether a salient or tombolowill form see fig. There two major types which are gravity.
