The New Yogyakarta International Airport has become one of Indonesia’s National strategic projects and potentially support the development of the Aerotropolis area around the airport. Located on the southern coast of Yogyakarta with rivers at the airport’s upstream, flooding can be a threat to the Aerotropolis area and the Yogyakarta International Airport. This research aims to investigate and model the flood review of the existing design of the flood control system of the Aerotropolis area and find out the possible option of better flood control in the area. The one-dimensional Hydrologic Engineering Center-River Analysis System (HEC-RAS) 4.1 was used to simulate the flood and its control in the Aerotropolis area. Simulation of flood control options includes river normalization, optimization of flood gates, retarding basin, and flood pumps. The present study proposed adjustment of performing in the use of a flood control alternative. Alternative flood control at each flood-prone area was adjusted to the level of flooding risk in the area. In conclusion, the use of retarding basin and flood pumps highly recommended to prevent flooding at the Aerotropolis area of Yogyakarta International Airport.
