Over het archief
Het OWA, het open archief van het Waterbouwkundig Laboratorium heeft tot doel alle vrij toegankelijke onderzoeksresultaten van dit instituut in digitale vorm aan te bieden. Op die manier wil het de zichtbaarheid, verspreiding en gebruik van deze onderzoeksresultaten, alsook de wetenschappelijke communicatie maximaal bevorderen.
Dit archief wordt uitgebouwd en beheerd volgens de principes van de Open Access Movement, en het daaruit ontstane Open Archives Initiative.

| Abstract |
In the presence of current and wind, submerged topographic features of the seabed produce contrasts in radar images. These contrasts can be quantitatively understood and modeled, based on hydrodynamics and electromagnetic scattering theory. A suite of models has been developed based on the generally accepted imaging mechanism, which consists of three steps: (1) surface current modulation by the bathymetry, (2) modulation of the (small) wave spectrum by wave-current interaction, and (3) radar backscattering by the sea surface. In order to invert this depth-radar backscatter relation, a data assimilation scheme has been developed. These numerical models have implemented, leading to the Bathymetry Assessment System (BAS). An example of an application in the Dutch coastal waters is presented. |
