• Three-Dimensional Cyclic Behaviors of Multiple Sandbars on the Ishikawa Coast, Japan

抄録

The characteristics of spatiotemporal variation of the multiple bar system on the Ishikawa Coast, Japan, have been investigated using a set of field surveys collected over 51 years. For the time variation, the behavior of sandbars is characterized by the presence of cyclic cross-shore migration of outer bars with approximately 10-year return period. Five cycles have been recognized from 1960 to 2010. The evolution of outermost bar strongly exhibits three-dimensional features. On the contrary to the bar migration patterns observed at many of other sites, the bar position are observed to move landward during the decaying phase.
