Sutami Dam has the largest reservoir In East Java. This reservoir has been operating for more than 46 years (operating in 1972 and the latest data as a reference in 2018). Data Aspect for analysis then calibrate with data in 1972 for comparison and to see the trend of sediment for 46-year operation. To find out the sediment carrier area, the review point is selected. The review point as a source of sediment in the Sutami Reservoir is divided into two sediment points with direct inflow to the Sutami Reservoir (Metro River) and the Sengguruh Reservoir outflow (Brantas River and Lesti River) and compare with Erosion from the field. These three points were calculated by sediment discharge to determine the most influential sediment carrier points in the Sutami Dam. The greatest Sediment carrier is from the Sengguruh Dam outflow (Brantas River) with Qs = 2.34 kg/s (2018), then from the Metro River with Qs = 2.27 kg /s (2018).
