Abstract
Floods are recognized as one of the main risk factors to cultural heritage sites. However, flood risks in these areas are mainly considered in flood protection schemes from a civil engineering point of view. Changgyeong Palace is one of the major palaces of Seoul, Korea, and is home to the national architectural heritage. It experienced a flood on July 28, 2011, when extreme rainfall struck Seoul. This study examined the flood events at Changgyeong and analyzed the flood risk based on flood risk analysis models, using a map of the observed inundation. Flood risk analysis models, including Hydrologic Engineering Centre–Hydrologic Modeling System, Storm Water Management Model, and Geographic Information System, were used for further analysis of flood risk scenarios (100-, 200-, and 500-year return periods). The flood risk analysis carried out in this study revealed that flooding which occurred at Changgyeong Palace was due to an insufficient urban drainage network enclosing the site. The flood risk model was used to simulate possible flooding areas based on flood risk scenarios. Although the architectural heritage would be safe from inundation in all flood risk scenarios, the lower part of Changgyeong Palace has a high risk of flooding.
