One of the problems Padang City currently is the threat of floods. Maransi flood canal is a one of drainage building which can accommodate and drain the flood discharge. Maransi region and Aie Pacah is one of the flood-prone areas in the Padang City. Maransi regional flood control, Aie Pacah and surrounding area are being made with the construction of the vast maransi flood canal with catchman area 17,13 km2. This needs to be analyzed to determine the ability of the Maransi flood canal to accommodate maximum flood discharge. The data obtained from the local rainfall stations, agencies, field observations, literature and consultation with relevant parties. Rainfall estimates using rainfall data at last 10 years and using the method of Gumbel, Hasper, Wedwen. The calculation of flood discharge plan using the Rational method with 5 year annual return period for discharge is obtained 383 m3/sec. From maximum flood discharge plan, flood canal dimensions are obtained with wet sectional area 88m2, wet circumference 29,31m, Fingers Hydraulic 3,00m, speed 4,60m/sec. From dimensional analysis results are then compared with the dimensions of the existing flood canal known to percentage of discharge that can be accommodated is 81%. To reach the 100% capability to accommodate the maximum flood discharge the flood canal banks must be added height 55cm. Maransi flood canal development is was also adjusted to the Study Report On Padang Area Flood Control Project, JICA (Japan International Cooperation Agency), December 1983.
