Abstract

Abstract: Semarang city in central java Indonesia has a strategic location as the capital of Central Java Province and developed into the fifth largest metropolitan city in Indonesia. The city of Semarang, which is traversed by the north coast route (pantura) is often flooded during the rainy season. This is because the intensity of rainfall is high and some areas in the city of Semarang are rob areas so that when there is a tide of sea water this area will be flooded. The combination of the Flood model and the weather prediction model will illustrate future conditions. The results showed that the prediction of flood distribution based on rainfall for a period of 10 years. With the flood model the period pattern of rainfall intensity values obtained is processed into a relationship graph between the duration of rain in minutes with the intensity of rain in the return period of 2 years, 5 years, 10 years and 25 years. The rainfall intensity value obtained will then be used to determine the peak discharge value
