Analisis Normalisasi Sungai Baubau

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).
