アイスランドの融氷河流扇状地の位置づけ : 沖積扇状地の定義の確立に向けて<平成17年度 助成金使用報告>
Not only outwash fans but also stream-flow fans have been discussed as to whether or not they are involved in alluvial fans. In this study the Skeidara outwash fan in Iceland is examined by checking various definitions on alluvial fans. The criterion that alluvial fans are steeper than 1.5 degrees i...

In this study the Skeidara outwash fan in Iceland is examined by checking various definitions on alluvial fans.

Gentle stream-flow fans with mean slopes steeper than 2‰ or 0.11 degrees in Japan are recognized as alluvial fans therefore, the Skeidara outwash fan with a mean slope of 3.9‰ or 0.22 degrees can also be regarded as an alluvial fan on the basis of its longitudinal profile. Although the apex is around the valley mouth of Morsardalur, it is at the front of the Vatna glacier. Therefore, the fan is not considered to be an alluvial fan in the narrow sense that it is formed at the valley mouth. However, the possibility of it being an alluvial fan in a narrow sense remains because of the following probable events-the main fan body had been built at the valley mouth, and the body was modified subsequently by outwash flow.
