Figures & Tables

a.) Overview of the River Rhine catchment with the location of Strasbourg. b.) Comparison of the Upper Rhine system before and after river engineering works in the 19th and 20th century. c.) Historic development of the study area from AD 1778 until 2010.
Schematic sketch of the sampled exposure.
Example of IRSL decay for a multi-grain disc and a dose response curve of sample RO1-4 (inset).
Representative single grain IRSL decay of sample RO1-4.
Results of thermal transfer tests experiments reveal a slight increase of De with increasing preheat temperature. Same applies for recuperation as monitored in the dose recovery experiments.
Results of the dose recovery tests for both multi-grain aliquots and single grains.
Light sum curve of single grain data of four samples.
This example of a fading test displays a g-value of 1.6 ± 0.4 %/decade.
Result of the single grain fading test.
Dose distributions plots of multi-grain aliquot and single measurements of all samples investigated. Three De values of 19.1 ± 1.6 Gy (RO1-5 MG), 11.9 ± 0.4 Gy and 17.2 ± 0.8 Gy (RO1-6 MG) are not shown in the plot to improve presentation.
Change of De when assuming different overdispersion values in the Minimum Age Model of Galbraith et al. (1999).
Plot of IRSL ages for different approaches versus the timeline reconstructed from historic records.

Summary data of luminescence dating for both multiple grain (MG) and single grain (SG) approaches with sampling depth below surface, the concentration of dose rate relevant elements (K, Th, U), assumed average water content (W) during burial, dose rate (D), mean De values calculated for the Central Age Model (CAM) and Minimum Age Model (MAM), using σb values of 0_10 (MG) and 0_20 (SG), the fading corrected MAM De, the resulting IRSL ages for MAM (before AD 2015), and the age transferred into AD time scale_
