    In most coastal and estuarine settings the seabed elevation (water depth/bathymetry) changes due to the processes of sediment and sediment deposition on a daily basis. More pronounced changes occur when wave energy can penetrate to the seabed during winter storms. Changes in seabed level greater than ~0.10 – 0.15 m can be detected using conventional […]
