WebAttension® Sigma 700/701 force tensiometers can be used to evaluate the amount of sedimentation of a suspension due to gravity. The suspension liquid is kept still and the balance of the tensiometer measures the mass change of the sedimentation probe within a time period. The higher the mass change is, the faster the sedimentation process occurs. Web12.6 Sediment Distribution Now that we have an understanding of the types of sediments found in the ocean, we can turn our attention to the processes that cause different types of sediments to dominate in different locations. Sediment accumulation will depend on the the amount of material coming from the source, the distance from the source, the amount of …
