Abstract The problem of flooding in a Watershed (Basin) or region is caused by natural conditions, such as relatively high rainfall, sloping topographic conditions and tidal influences. Human behaviour is often also the cause of flooding problems, such as the location of settlements that are in the river borders or industries that dump waste directly into river bodies. Besides the problem of flooding can also be caused by a not well-organized river/drainage system or lack of maintenance of an existing river/drainage system. Furthermore, social problems include increasing demands for the availability of new and good residential environmental infrastructure. To overcome the problems as described above, before an activity such as build in a left/right inspection road planning, is need analysis rainfall data and make patterns of Intensity Duration Frequency (IDF) Curve to an analysis of hydraulics in determining flood discharge plans. The results showed that the discharge of river capacity of Air Lakitan river was 482.74 m3/seconds, so the river is unable to hold water flow.
