Surabaya City, for Jalan Petemon gg IV, Petemon Subdistrict, Sawahan District, with an inundation area of ​​0.413ha, inundation height 12.407cm, inundation length of 54.667 minutes. These problems are caused by drainage channels caused by man or nature itself. The purpose of this research is to find out the flood and inundation discharge for the next 2 years on Petemon 4, Petemon, Sawahan, Surabaya, to analyze the condition of the existing drainage channels on Petemon 4, Petemon 4, Petemon, Sawahan, Surabaya , to find alternatives for flood and inundation countermeasures for these channels. able to drain the rain discharge well. The research method of calculating the rain discharge design uses the Nakayasu method.
