Outline of Final Research Achievements

The most typical landform type in steep Japanese mountains is V-shaped valleys. However, their detailed geomorphological characteristics have rarely been investigated, probably because they occur very commonly. This study utilized digital elevation models and geographical information systems to quantitatively and statistically analyze cross sections of valleys including V-shaped ones. Based on the results, geomorphological characteristics of valleys and their controlling factors were discussed. In addition, valley-forming processes such as slope failure and sediment yields from valleys were investigated. The study areas included Japan, Taiwan, southeastern China, and the western Arabian Peninsula.
