Open Space as Evacuation Areas on Super Levees along the Arakawa River, Japan

Abstract

The objective of this study is to re-evaluate the conceptualisation of super levees by focussing on the availability of open spaces as evacuation areas along the Arakawa River. By using land use, occupation and cross-section analysis, this study found that open spaces on super levees able to accommodate a large number of evacuees. This proves that the development of super levees is undeniably ready to provide sizeable safe upland evacuation area for nearby residents. This study also implies that the future development of super levee should include more open space by the development of a public park on the site.
