CONTROL FUNCTION OF SAND TRANSPORT AND VISIBILITY OF ARTIFICIAL HEADLAND AND GROINS ON NUMAZU-USHIBUSE COAST

Abstract

 After the designation of Mt. Fuji as a World Cultural Heritage, “Mihono-Matsubara” became one of the constituents of the natural scenery of Mt. Fuji from the shoreline, where beach has been eroded. As a measure against beach erosion, L-shape groins were proposed. Such structures have a possibility of damaging scenery from the shoreline because of their protrusion. Control function of sand transport and visibility of such structures were investigated using bathymetric survey data and aerial photographs, taking the Numazu-Ushibuse coast as an example.
