Abstract

Flood is routinely happen in several cities in Indonesia that always becomes problems. The objectives of this research are to analyze scheme flow, drainage canal exsisting condition, and drainage canal design. Data processing in this research divided into three steps. First step, 10 years maximum daily rainfall was processed and then flow pattern was analyze. Last step drainage canal was designed. Base on analysis scheme flow is in conformity with existing condition. Run off coeficient range 0.29 to 0.54, whereas two-years period was used as discharge plan that range 0.2 to 2.2 m3/s. The results shows that drainage canal in sub catchment 1C, 1E, and 2A, 2B should be rehabilitated. As for a culvert in sub catchment 1A- 1B should be rehabilitated to be round type sinks with 80 cm for diameter and be equiped with control box for prevent backwater in channel. Problems occurs at the inlet which is not accordance with standard planning for inlet structure where maximum spacing of inlet at canal is 5 m. Based from unit price analysis, drainage canal planning arounds Jalan Meranti-Tanjung costs 512 Million IDR.
