The numbers of design rainfall for 5 years and 10 years was 169,365 mm and 171,502 mm; while the design discharge with return period of 5 and 10 years, for example, in channel 1 was branch 1 was of 0,6772 m³/s and the main channel was 5,7910 m³/s; The economic channel dimensions for the main channels 1 and 4 were the base width B = 1,596 m ≈ 1.6 m and the water height h = 0,796 m ≈ 8 0,8 m, the cross section was square.
