| Abstract |
Within the scope of the long term vision of the Schelde Estuary and the Development Outline 2010 low dynamic intertidal and shallow water areas are considered to be of high ecological value. Little is known about the occurrence of such valuable reas in the Schelde Estuary, nor are the physical and morphological processes which determine the occurrence of these areas fully understood. Based on the results and recommendations of a 2008-2009 research project in the Westerschelde, a new research project was defined to determine relationships between abiotic (bedforms, hydrodynamics, sediment) and biotic (benthos) characteristics in the Zeeschelde (Belgium) and to set up a classification of deep and undeep subtidal areas. A first phase in the habitat classification comprises of the analysis of bed form occurrence and the setup of a bed form classification based on multibeam echo sounding data. Results show within the different sub areas a variation in bed forms going from hard bed layers to no bed forms to ripples (H ~ 0,1 to 0,3 m | L ~ 10 m) and smaller dunes (H ~ 0,5 to 1 m | L ~ 15 to 25 m). On-going research investigates relationships between the bed form characteristics and flow and sediment characteristics. Preliminary results. |
