| Research Abstract |
A radar network, set up from four X-band radars, has been operated to observe the morphological changes of a 17km long sandy coast and propagation of river plume fronts. Shore line positions at the ends of the area, natural sections and sections with coastal structures were measured continuously. Cross correlation analyses on shoreline position variations revealed that an anti-phase variation between central portion and ends of the area was existent. Sediment fluxes were estimated from the shoreline changes around the coastal structures, which showed a seasonal cyclic change.
