Dec 30, 2017· Sed rate, or erythrocyte sedimentation rate (ESR), is a blood test that can reveal inflammatory activity in your body. A sed rate test isn't a stand-alone diagnostic tool, but it can help your doctor diagnose or monitor the progress of an inflammatory disease.

Calculation of the sedimentation rate applied to your case

What is the sedimentation rate. Sedimentation is a physical water treatment process that uses gravity to remove suspended solids from the water. Solid particles carried by turbulent water can be removed naturally by sedimentation in a calm zone of water, such as ponds or lakes.

The Reservoir Sedimentation Database (RESSED)

BACKGROUND. Overview: Sedimentation rates in reservoirs have long been and continue to be of interest to the Subcommittee on Sedimentation (SOS) member agencies, as well as others. Much of the original impetus for conducting surveys to calculate sedimentation rates in reservoirs was to gain a better understanding of the role(s) of reservoirs on watershed sediment-transport processes, so that ...
