Checkdam is a controlling building created because of the flow of water with a large enough sediment concentration, where the sediment comes from soil erosion in the upstream part of the river, to find out the analysis of hydrology, regarding its rainfall, analyze the flood discharge. With the form of a checkpoint in the village of Notorejo, it can prevent and reduce disasters due to the flow of sediments that are formulated in such a way that the river concerned can function normally and effectively in terms of two angles, namely flood control and river development. Rainfall based on calculation of log pearson type III on R20 is 100mm, and Flood Debit Plan 167 m3 / dt. The ability of the sediment capacity of 700,692 m3 / dt and the capacity of sediment capacity to remain 525,519. and able to withstand shear force and rolling stability, this discharge plan is useful for reducing sediment that enters the river salts and provides safety of surrounding agricultural areas due to erosion, stabilizes the riverbed, directs river flow and reduces the occurrence of breakdowns in bridge structures along the river flow mate. Keywords: checkdam, hydrology, sediment, flood discharge, stability.
