Adaptive Coastal Preservation Measures with Consideration of Fluctuation of Climate Change

Abstract

A way of thinking about the adaptive measures to the coastal protection which considered“a fluctuation” of the climate change, was proposed. Definition of“fluctuation” in this paper is a change in climate caused by the volcanic eruption, El Nino Southern Oscillation (ENSO), 11 years of the solar activity together with anthropogenic changing trend and several decadal oscillation of ocean. Considering such“fluctuation”, discussions were made how we should design coastal structures, manage shore environment and establish the coastal disaster prevention measures in the near future of several decades.
