Cohesive Strength Meter
Field Measurement of Sediment Erodibility
An understanding of the erosion potential ('erodibility') of sediments is important for a wide number of contemporary environmental issues, including benthic habitat stability, contaminated sediment dispersal, river bank and agricultural land stability and the geomorphology of estuaries and coastal areas.
The Cohesive Strength Meter is a field instrument which directly measures the surface erodibility of marine, fluvial and terrestrial sediments. The instrument permits rapid assessment of sediment critical entrainment stress (stresses in excess of 12Nm-2 may be imposed on sediments) and also provides a relative measure of erosion rate.
The instrument is highly portable and can be carried by hand to a field site or transported in the lightweight custom designed back pack system (optional extra).
Capable of conducting up to 100 tests per run and with up to 80 predefined test routines, the CSM is internationally recognised as the leading device for the rapid in situ measurement of sediment erosion.
