Recently, in Korea, localized heavy rainfall events have occurred frequently due to climate change. Especially, since urban areas depend heavily on pump and pipe systems, extreme rainfalls that exceed the design capacity of drainage facility result in increasing inland flood damage. This study proposed a methodology to analyze urban flood damage characteristics in inland flood prone areas. After firstly constructing rainfall scenarios which have various durations and intensities, inland flood scenarios were developed using XP-SWMM. This study presented the inland flood damage analysis (IFDA) to calculate inland flood damage from the inland flood scenarios. Based on the inland flood scenarios and corresponding flood damage curves, the characteristics of damage due to inland flood were analyzed using the relationships among precipitation depth, flood depth, and flood area. The proposed method can be used to identify the storm event resulting in heavy flood damage, and to predict the flood area, depth and damage from various storm events.
