简介:Bathymetry in the nearshore changes continuously under energetic interactions
with shoaling and breaking waves. A large storm can bring about significant changes
of the nearshore bathymetry on a time scale of an hour. 简介:Bathymetry in the nearshore changes continuously under energetic interactions
with shoaling and breaking waves. A large storm can bring about significant changes
of the nearshore bathymetry on a time scale of an hour. Nearshore bathymetry is
required to describe depth-induced wave changes and large-scale fluid motions. The
evolution of nearshore bathymetry will be predicted based on current bathymetry and
nearshore hydrodynamics. Depth inversion methods by remote-sensing have been de-
veloped to cover a large span of spatial and temporal scales, substituting conventional
labor-and-time intensive in-situ bathymetry survey methods. However, earlier depth
inversion methods have limitations at estimating bathymetry accurately in the surf
zone because of image noise due to foam induced by wave breaking in the surf zone.详细>
