Description :
The AA. compared the results of 4 independent reconstruction methods – optically stimulated luminescence (OSL) dating, caesium-137 (137Cs) dating, heavy metal analysis, and flood bed interpretation – applied at 3 embanked floodplain sites along lower Rhine River distributaries in the Netherlands. Intercomparison of the results of the different dating methods revealed the potential errors associated with each method. Using the results the AA. indicate the optimal spatial range of application of each method, depending on sediment texture and sedimentation rate. The optimal spatial and temporal ranges differ for each method, but show significant overlap. A combination of the methods will thus provide maximum information for accurate estimation of sedimentation rates on a decadal time scale.
