Vertical accretion rates in fluvial systems : a comparison of volumetric and depth-based estimates

Auteur :
RUMSBY, B.

Description :
This study compares depth- and volume-based estimates of sediment accumulation for well-dated vertical accretion sequences at Broomhaugh Island in the Tyne basin, northern England. High resolution dating control (based on heavy metal stratigraphy and cartography) coupled with detailed reconstruction of channel geometry allows accumulation rates to be calculated for the last 300-400 years. The results show a marked disparity in the magnitude and pattern of vertical accretion rates between the 2 approaches.
