Description :
For 3 periods of 9, 8 and 17 years sediment transport computations are made with 2 series of relationships between sediment transport (Qb) and discharge (Q) in which the condition of the armour layer is taken into account. These sediment-transport-discharge (Qb/Q) relationships are determined by local bed-load transport in the Common Meuse. The survey data in the Common Meuse were analysed with a geographical information system (GIS) (ARC-INFO) to produce maps of the river-bed level. The subtraction of maps of bed levels in different years results in a map with spatial distributions of erosion and sedimentation.
