The flood that has occurred in Tangerang City is a problem that has not yet been resolved. The flood originated from Bogor through the Cisadane River. Cipabuaran Channel is one of the channels in the Sabi River watershed that often overflows. Sabi River itself is a tributary of the Cisadane River. In this study the flood control simulation in Cipabuaran Channel was carried out using a 1D-2D numerical model. Simulation is carried out with 4 scenarios based on the design flow of the 10 year return period. for scenario 1, flood control is carried out using retention pond in the downstream of Cipabuaran Channel, scenario 2 is carried out by using two retention ponds in the upstream and downstream of Cipabuaran Channel, scenario 3 using retention ponds in the downstream of Cipabuaran Channel and bypass channel to Cisadane river, and scenario 4 performed by using retention pond in the downstream of Cipabuaran Channel and normalization on the Channel. Simulation results show the effectiveness of flood reduction for each scenario, for scenario 1 flood can be reduced by 9%, scenario 2 flood can be reduced by 32.52%, scenario 3 flood can be reduced by 77.34% and for scenario 4 flood can be reduced by 95%. From these results it can be concluded that scenario 4 where flood control is carried out using retention pond in the downstream of Cipabuaran Channel and normalizing the River can reduce flooding significantly.
