Abstract

Batang Kandis River was located at Padang Pariaman Regency, West Sumatra Province. This river is one of the rivers that empties into the Batang Anai river, one of the large river that empties into the Indian Ocean. Location of this river is important because could resulting flood that can impacted on Minangkabau International Airport (BIM) environment and Padang city also. Flood that was occurred generally caused by exceeding of maximum flow at Bank full Capacity. In this study, a review will be carried out on the ability of river cross capacity to flood discharge. HEC RAS simulation was carried out with the upstream condition is flood discharge and tidal water elevation as the downstream condition. Study using discharge for a 10-year return period (524.42 m3 / s) and a 25-year return period (593.76 m3 / s) show flood overtopping along the river. Flooding due to velocity decrease caused by river meandering and influence of sea water intrusion. Modeling using unsteady flow can be done to see tidal propagation towards the river. Alternatives of river straightening can be simulated to see the changes in flow characteristics that occur and their impact on increasing discharge to the sea.
