Effective countermeasure is required for the issue of wind-blown sand generated from nourished beach to hinterland in Niigata West Coast. Double-row sand fences on a parallel with coast and wing fences having with the fence height of 2m have installed in 2005. The comparison was made with past observation results after conducting site observations in the winter season (November, 2006 through February, 2007) in this study. As the result, the volume of wind-blown sand reaching to hinterland was decreased to around 1/10,000 to 1/100,000 comparing with the volume without fences and it has been confirmed that the countermeasure by double-row sand fences and wing fences are extremely effective. The cheaper countermeasure by reducing the number of fences is to be studied.
