ABSTRACTRecent overbank deposition of fine grained sediments along Swedish rivers is a rare process. Favourable conditions for overbank deposition exist, however, near the base level of low gradient rivers on the central Swedish plains. Lack of sedimentation data has inspired us to make this study which aims to estimate the present sedimentation rate and to test a field method to observe the spatial variation in deposition, by using simple sediment traps. The study area lies within the River Fyrisån drainage basin, previously investigated in several studies of fluvial geomorphology and sedimentology. The suspended sediment transport was calculated from actual discharge figures and from concentration figures obtained by water sampling and by using a“Surface Scatter Turbidimeter”. The total sedimentation in the deposition area was estimated in three ways, i.e. from actual figures on sediment transport, by a sedimentation formula and by using the results from the sediment traps. The surface deposition rates varied between 8 and 240 g/m2. The accuracy of the different methods is discussed in this paper.
