Abstract

Flooding is a problem experienced in area. In the Sadar river watershed are urban areas and mountainous areas. Sadar river has many tributaries. The flow characteristics have a large flow velocity. Sadar river passes through urban areas and empties into the Brantas river. Floods often occur in the Mojokerto area. Flooding occurred due to changes in land use, increased erosion of land in the Sadar river watershed. To overcome flooding in the area, temporary storage (polder) is used. Polders are a low plot of land, surrounded by embankments or embankments that function to avoid contact with water from outside areas other than those manually flowed to control flooding. From the channel capacity analysis using the HEC-RAS 4.0. Sadar river in the existing condition is unable to accommodate flood discharge with return period 25 years. Polders on the Sadar river are planned to use an alternative experiment 6 with the discharge entering the retention pool by 95%. The planned retention pool is 5 pieces.
