ABSTRACT

This study tried to reveal influences of alluvial landforms on change of urban spatial structure with case studies of Iksan, Chungju, Jinju, Masan and Pohang in Korea. Urbanized area in Iksan has been continuously located on hill to avoid flood, and urbanized area in Chungju began in narrow valley and has been expanded to gently-sloped mountain. Jinju, located on fluvial terrace, has expanded its urbanized area to relatively high flood plain rather than to steeply-sloped mountain. Urbanized area in Masan was located on alluvial fan and has been expanded to coastal plain including reclaimed land. Continuous urban growth in Masan has led urbanized area to occupy almost every gently-sloped region. Pohang has been continued to expand its urbanized area based on delta, while valley and mountain have been occupied by urbanized area since most regions with a low risk of flood on delta were developed.
