The Upstream Bekasi River flood covering an area of 326 ha in 15 inundation points covers five sub-districts of Bekasi City. The Upstream Bekasi River has 2 (two) tributaries, namely Cikeas River and Cileungsi River. The Upstream Bekasi River flood was caused by a relatively small cross-sectional capacity of the river, namely 391.79 m3/s, while the flood discharge that occurred was relatively enormous, namely 708.75 m3/s. The flood was caused by the Cikeas River at 199.47 m3/s and the Cileungsi River at 509.28 m3/s. In order to control floods in Upstream Bekasi River, a dry dam series is planned in Cikeas River and Cileungsi River. At Cikeas River, the Ck-227 weir was built, while at the Cileungsi River the Cl-1 weir was built. The methods used consist of data collection (rain, map of the earth; and the topography of Cikeas and Cileungsi River and the capacity of Upstream Bekasi River), determining the flood discharge design for Cikeas River and Cileungsi River, determining the location; high; the number and dimensions of the weir outlet doors, as well as the flood simulation until the Cikeas River discharge + the Cileungsi River discharge < Bekasi Hulu River discharge. Based on the results of the flood simulation, it is found that at the Cl-1 dam, with the input of the peak flood discharge of 509.28 m3/s, the peak flood output becomes 198.40 m3/s. While at the CK-227 Dam, with a peak flood discharge input of 199.47 m3/s, the peak flood output is 170.40 m3/s. The simulated flood discharge of Cikeas River and Cileungsi River is 368.80 m3/s, smaller than the channel capacity of the Upstream Bekasi River, which is 391.79 m3/s. So it can be concluded that the flood in Upstream Bekasi River can be controlled by building dry dam series in Cikeas River and Cileungsi River.
