Abstract

A Good of groyne placement on the curve channel were the lower of flow water on near groyne. This conditions will occurred the sedimentation field. This research having a goal to development the relationship of groyne placement at the curve channel with sediment field accumulation occurred, so that this research will be done by modeling of groyne placement using mathematical modeling approach by finite different method. Research modeling had be simulation many case of groyne placement applied to the curve channel where the radius bend equal 40 m and 30 m. The research done 288 times simulation to the many case of groyne placement on the river bend. Many case of groyne placement on the curve channel were combinations of two various of the radius bend, three various the groyne position and three various of groyne length. On each of them be simulated used 4various of the flow velocities and 4 various of the sediment suspended concentrations. The resulting simulation many case of groyne placement will be analyzed bring in the relationship of the effect groyne placement at the curve channel to sediment accumulation occurred.
