    Abstract

    This study analyzed the wind fields around an artificial straight dune by large eddy simulations to investigate the mechanism of its separation into smaller dunes in more than 10 years at the Kashima Coast. The results showed that the change in ground height at the leeward slope was positive at almost all locations, but negative approximately every 50 m when the inflow wind was from an onshore direction. The change decreased approximately every 100 m where the inflow wind was from an offshore direction. The change in 15 years was positive at almost all locations, but at some locations on the south side, the change was negative; however, the change had no noticeable periodicity along the dune.
