ABSTRACT
The role of floodplains in storing excess of water from floods can be strengthened by planting bamboos in order to increase the hydraulic roughness of the land. This research tried to make a model of bamboo planting in the Barabai River floodplain with the aim of controlling floods. The research method being used was an experiment on the physical model of the Barabai River cross-section and its floodplain at the laboratory with a scale of 1:110, in which clumps of bamboo with the spacing of 1.82 cm x 1.82 cm were planted. The model was placed in a flume of 6 m long, 0.4 m wide and 0.6 m high. The experiment was done by releasing discharge until the floodplain was inundated and the height of inundation was measured. The experiment aimed to find out the hydraulic roughness value of the Barabai River floodplain. Research results showed that the hydraulic roughness of the Barabai River floodplain (n) was 0.104; for the sandy channel, the value of n was added with 0.022 so that the total n being used was 0.126. With the value of total n, the length of bamboo planting was adjusted. When the length of bamboo planting was 503 m from location A, there was a 13.18% decrease in the amount of flood discharge at location D. When the length of the floodplain being planted was increased 8.5 times, there was a 91% decrease in the amount of flood discharge at location D.
