【 摘 要 】

In Banyuwangi Regency there are four major rivers include the Tambong, Bomo, Setail and Baru river. Those rivers often overflow due to the high sediment deposition in the weir. The purpose of the study is to determine the influence of sediment loads upstream and downstream of the four rivers on irrigation impact. Suspended load analysis used method of Engelund and Hansen; Einstein; and Chang Simons & Richardson. Bed load analysis using methods of the Meyer-peter; Duboys; and Shields. Loads of sediment, both suspended load and bed load on the irrigation discharge in both the upstream and downstream of the major rivers in Banyuwangi greatly influences the sedimentation of irrigation channels which affect on fluctuations of irrigation discharge to irrigate land of Agriculture. The Baru River carried the largest sediment load in irrigation intake of Karangdoro Weir that carried Qs of 385.96 tons/year and Qb of 6.37 tons/year. It is necessary to have policies and efforts to control sediment and study about the maintenance of weirs periodically to maintain the volume of irrigation water so that it can increase agricultural productivity in Banyuwangi Regency.
