Floods are hydrometeorological disasters that often occur in various regions, including in Nganjuk Regency. From 2019 to 2022, there were urban floods that inundated highways, markets and hospitals and disrupted community and government activities. Heavy rain is one of the causes of flooding. Rain intensity, duration and frequency (IDF) curves were constructed using rainfall data from six rain gauge stations. This curve is used to determine the 10-year and 25-year probabilities of PUH intensity and the probability of causing flooding in Nganjuk District. Rain intensity in Nganjuk Regency is PUH 10 and 25 with an average rain duration of 15-60 minutes which is included in the moderate rain category, namely 20-50 mm/day. The results of this analysis will become the basis for consideration in formulating policies and strategies for urban flood disaster prevention and management in Nganjuk Regency. Therefore, coordination between the city government and the government is needed to reduce the risk of urban flooding in Nganjuk Regency.
