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 |
Land- and seascapes are complex systems heterogeneous in space and variable in time. Land- and seascapes can be characterized by attributes and exchanges of energy and mass between these attributes. Under such conditions the most realistic interpretation of nearshore land- and seascapes is as open systems, with multiple interactions between attributes and environment.Spatial trends of vegetation cover/typology, sediment/soil distribution, and seabed classification could be implemented to obtain detailed classification from both optical and radar satellite data. These are obtained by means of subpixel processing techniques (e.g., spectral mixing analysis). Then, classifications are analyzed in terms of spatial (power law) and temporal (empirical orthogonal function) patterns. The specific added value of the remote sensing mapping methodology can provide an integrated assessment of coastal dynamics, as it allows both environmental and anthropogenic change analysis, giving new insight to the management policy for coastal ecosystems. |
