鳥取沿岸の総合的な土砂管理ガイドラインの策定と実施

抄録

A guideline of the comprehensive sediment management in littoral system including rivers, being main supply source of sand to coasts, was made to simultaneously solve not only beach erosion, but also surplus accumulation of fine sand inside the fishing ports, ports and river mouths. The method of sand recycle (sand back pass) is proposed instead of local optimization using hard structures against beach erosion. To overcome ordinary inconsistent measures under the sector-by-sector system, unique target to preserve coastal land was set in entire Tottori Prefecture. The plan was put into practice in 2005.
