River normalization and cliff strengthening are efforts to control flooding that occurs in rivers such as the Baubau River. In 2012, there were floods in 20 spots due to the overflowing of the Baubau River so that a flood prevention plan is needed. This study aims to determine the method of flood management in the Baubau River, with variable of cross-sectional areas (1) river topographical data, (2) land use and soil bearing capacity (1) soil shear force, (2) rolling force and the river length studied is about 1.3 Km. The results of the analysis show that the flood discharge of Baubau River is (1) 10.69m3/s, 2 year return period, (2) 15,39 m3/s 5 year return period, (3) 18,50 m3/s 10 year return period (4) 22,43 m3/s for 25 years, (5) 25,35 m3/s for 50 years, (6) 28,25 m3/s for 100 years, so the handling method used in the Baubau River is to normalize the river with a trapezoidal model (b = 3,69 m, B = 10,40 m, h = 3,20 m, H = 4,46 m, and W = 1,26 m for the 25 year return period) and the strengthening of cliffs on the right and left of the talud model ( h = 5.7 m, bottom width 3.5 m, and top width 0.5 m). |
