Spatial hydrogeomorphological influences on sediment and nutrient deposition in riparian zones : observations from the Garonne River, France

Description :
This paper investigates the influence of geomorphological setting on riparian zone sedimentation within a reach of the River Garonne during 3 major floods. The sampling design was stratified to reflect landforms constructed by fluvial processes (e.g. floodplain, lateral benches, islands, side channels and point bars). Observed sedimentation varied significantly with flood event, planform context, landform type and associated vegetation cover and, in some cases, with sample location within the landform. A conceptual model is proposed which considers the spatial pattern in riparian zone sedimentation according to riparian morphology and flood magnitude.
