They are utilized in river bank protection as well as restoration projects (e.g., restore fish habitat in degraded streams). This movie shows the case of accidental pollution, a series of groynes can substantially modify the dispersion of the pollutant cloud in the river reach.</br></br>Bridge Pillars that support the structure change the flow field and promote local differences in sedimentation and erosion.

A groyn is a rigid hydraulic structure bui … A groyn is a rigid hydraulic structure built from an ocean shore (in coastal engineering) or from a bank (in rivers) that interrupts water flow and limits the movement of sediment. In some cases it keeps velocity in the main channel such that it is suitable for shipping. </br>In a river, groynes prevent bank erosion and ice-jamming, which in turn aids navigation. The areas between groups of groynes are groyne fields. Groynes can be made of wood, concrete, or rock piles. Their use goes back many centuries.piles. Their use goes back many centuries. +
