Abstract

Slahung river in Balong sub-district has River Flow Area 56.96 km2. In Ponorogo, especially Balong sub-district, there are often flooding in raining season. One of them caused by Slahung river which in general needed special handling. It caused by the inability of the river to intercept water flow. The concept of the river management was flood control system with longitudinal section construction along the left and right the river. To find out the flood debt, counted by Nakayasu and rational method with repeating 10 years as the rain fall rate. From the calculation, there found total debt 150,058 m3/det, so it needed a river longitudinal section widen. After analyzing the water profile using standard phase method by dividing 80 poles and the duct wide, planned until finding a fit profile. River dimension in 1:1 slope, planned embankment with sand graving. After controlling the seepage and counting its stability, there found a save longitudinal section. The analysis fulfill the safety condition fit with the safety factor allowed.
