Abstract
Extreme Flood events due to climate change have been hit Semarang City several times. The disaster usually occurs because of the development of flood protection generally does not include climate change factors on the design flood. The paper was appointed to characterize rainfall run-off with 10 years of historical data from three rain gauge stations likely Wolo, Brumbung, and Maritim. The analytical showed annual rainfall and maximum daily rainfall tends to increase on average 2.139 mm per year, the number of rainy days tends to decrease two days per year. The future Intensity Duration Frequency (IDF) is needed to anticipate global temperature increases more than 2 degrees. Whereas the analysis for drainage capacity showed by the intensity return period of rainfall for 2, 5, 10, 25, 50, 100 years were 81.656 mm/ hour, 104.262 mm/hour,116.00 mm/hour, 126.511 mm/hour, 132.773 mm/hour, 138.030 mm/hour. With the findings, it is expected to develop a flood control system, simply considering the impact of climate change. Hence, the research is successful to predict the flood in a small catchment, with historical data only. The result contributed to one frame that it should take into account the necessity of flood mitigation, including the climate change impact.
