Cisadane a river flooded every year due to the reduced capacity of the river cross-section so that the river can not accommodate the flood discharge. One flood prevention efforts by raising cliff with concrete plaster. In this study, will be analyzed flood discharge capacity plan and cross-section of the river. Analysis of rainfall using the method of Log Pearson III, rainfall intensity calculations using the method of flood discharge Mononobe and analysis using method HSS Nakayasu plan. For the analysis of a cross-river capacity using Hec-Ras Software 5.0.1 and planning dimension of the river using the method of Manning. Results rainfall plan?(X?_100)of 143.3133 mm with the greatest rainfall intensity during the 6 hours that is 16.9349 mm. Flood mitigation planning Cisadane using Q_100 of 5085.8778 m³/ s. Having analyzed using the Hec-Ras and Methods Manning conducted elevation cliff with a variation of 2.82 m to 6.19 in the STA 2+779.22 - STA 4+253.88 with a decrease in water level up to 50.69%.} }
