Study on the Prevension of the Intrusion of Saline Wedge

Abstract

From engineering aspects, the techniques for the prevention of the intrusion of salhie wedge are quite important. This paper proposed boundary layer control method using barrier settled on the river bed to reduce the length of the saline wedge. Various type of barriers were tested their effectiveness.
Theoretical and experimental study were conducted on the critical intrusion length of the saline wedge due to the barrier. Both results were compared and revealed good comparison. Eaves effect which attached downstream side of the barrier to control the motion of lower layer was also studied and found its effectiveness.
