Classification on the basis of function Groynes serve.
Deflecting Groynes : A groyne perpendicular to the bank of the river.
Repelling Groynes : A groyne pointing upstream of river has the property of repelling the flow away from itself are called repelling groynes and these create scours which are formed due to vertical eddies. The scours formed are away from bank and near the head of groynes.
Attracting Groynes: A groyne pointing downstream is known as attracting groyne and these have property of attracting flow towards themselves, in this case also scours are created but are near the bank of the river.
