Abstract

The charasteristics of the crevasse channel and crevasse splay of Kinu River formed from the 2015 heavy rain in September were researched in terms of landforms and deposits. It was found that sedimental structures of these landforms were similar to the previous studied crevasse deposits, but the position the landforms created was largely influenced by the original topography, partly modied by human.
Applying the character of this crevasse landforms, it may be possible to nd other crevasse landforms created by past floods in this floodplain.
