Research Abstract

This research project looks at the performance of "beach nourishment" that has been occurring on the coast of Teradomari-Nozumi facing the Japan Sea since the full operation of the Okotsu diversion channel in 1931. The geomorphological studies showed that the formation of sandy beaches on both sides of the river mouth developed at a significant rate in the first thirty years or so, but undergoing a standstill from early 1990s on. This reasoning has led the research team to focusing on how the shoreward and offshore boundary conditions of the littoral cell have evolved, in particular, with respect to the fluvial supply and oceanic dispersal beyond the depth of closure. It is of importance to record here that the offshore sediment retrieval made immediately after the July 2011 Niigata-Fukushima flood event revealed the accumulation of the March 2011 Fukushima-event-associated radioactive nuclides there, enabling an otherwise unimaginable pursuit of sediment transport offshore.
