The Partrac Cohesive Strength Meter (CSM) is being used in the STELAR-S2S project. The overall aim of the STELAR project is to understand the importance of climatic and autogenic controls in determining the transfer of sediment from source-to-sink in one of the world’s largest rivers – the Mekong.

Floodplain characteristics and sedimentation will be obtained using the CSM and core sampling along the river channel. The CSM will be used for the initial characterisation of river bank materials and supplemented by floodplain bank stratigraphic analysis.

Floodplain accretion will be calculated using 210Pb activity from each of the cores.

Additional field studies are being completed to gather data for input into the model: bathymetry, current profiles, multibeam and suspended sediment data.

The STELAR project will provide the first comprehensive quantification of controls on riverine sediment fluxes, leading to new generic understanding of the relationships between climatic variability, fluvial processes and sediment flux to deltaic zones and the ocean.
