Abstract :
Cisadane watershed has an area of 1.366 Km2 and 125 Km in length across west side Bogor regency and empties into Tanjung Burung, Tangerang regency. With the condition of Cisadane watershed unable to accommodate flood discharge and soil structure easily eroded causing many critical dikes and narrowing on river body and resulted in flooding in rainy season. Flood prevention efforts are planned by using retaining walls. Flow profile analysis is performed using Manning, While for stability analysis of retaining wall using Coulomb Method and Finding peak discharge with Nakayasu Method.The flood controlof Cisadane River was designed by using Q10th which is sebesar 3207,88 m3/second and comparison of 28,655% water level. The results of the retaining wall building planning obtained that the widht of foundation is 4,6 m and the height of retaining wall is 5 m with shear stability against shear is 1,69 collapse of soil bearing capacity 1,94.
