Title: Flood impact analysis using GIS : a case study of Seoul, Korea
Author: Cho, Junghyun
Abstract: Flooding is an increasing problem in metropolitan Seoul and the management of floods and floodplains is a neglected priority for urban planning. The causes of flooding are triggered by heavy rain, or tropical storms, especially under conditions where soils are already saturated. Rivers overflow into surrounding built-up areas, bringing death and injury to people as well as considerable damage to buildings. Among the residents of Seoul, flooding is most often attributed to failure of the pumping system that is the city’s chief line of defense against inundation. However, other analysts believe that a major reduction in the amount of green open spaces is contributing to increased flood risks. The impacts of these events encompass tragic loss of life, damage to built and natural environments, and massive disruption to the lives of affected populations in the short term. In the longer term, the recovery and post-recovery phases can also cause distress, disruption, health problems, and financial hardship lasting many years. This professional report tries to focus the impact of flood on environment along Han River and Seoul, Korea’s flood prone area. Furthermore, this report prepares maps and its output that can be used during flood emergency in inundated areas. Arc GIS 10 software is used to analyze impact of flood in Seoul, Korea.
