Abstract: Severe sedimentation is observed in Pommeroeul-Conde canal, Belgium; and, as a consequence, the navigation has been interrupted for now 12 years. This situation is due to past alteration of the neighbouring river network: the outlet of River Haine has been connected to the upstream part of the canal, which now acts as a settling tank. In order to monitor the actual sediment inflow and to prepare future dredging works, a sediment transport measurement station is being installed on the River Haine. Some investigations on the sediment characteristics and on its diffusion in the flow have been performed in order to identify the best location for the sampling point. Some of these results are detailed in the paper, together with the first recordings obtained at the station.
