The Semarang River is a flushing channel located in the Semarang River Drainage Sub-System and has the potential to be used as a water tourism area with the concept of Historical River Front City Walk. The planned water tourism area is in the form of procuring boats in the Kota Lama area, which is a historic area in the city of Semarang. This analysis aims to hydrology and hydraulics model of the Semarang River using SWMM 5.1. The method is carried out by observing the existing conditions of the study area, determination of flood discharge plans, and hydraulic analysis. The analysis starts from the Simongan Weir Bridge upstream of the Semarang River to the Berok 2 Bridge, which is located in the Kota Lama area. The results showed the intensity of rainfall designed 25 years is 155.7 mm/hour with the capacity of the Semarang River in existing and planning conditions can still accommodate the flood discharge plan, and a weir with a height of 1 m is needed to maintain the water level in boundary condition so that boat tours can operate optimally.
