From the Introduction: Recently, new instrumentation has been developed that may have the ability to quantify sedimentation on the scale of 1mm or less; however, these instruments require laboratory and field testing to demonstrate their ability to accurately measure fine-grained sedimentation at the sub-millimeter scale. As part of the Dredging Operations and Environmental Research (DOER) Program, researchers at the USACE Engineering Research and Development Center-Coastal and Hydraulics Laboratory (ERDC-CHL) are currently testing and evaluating some of these technologies. One such instrument is the SediMeter™, designed by Lindorm, Inc. SediMeter™ utilizes infrared optical backscatter (OBS) detectors to determine bottom location. This report will present the results of a series of laboratory tests that were conducted to determine the instrument’s measuring accuracy and assess its capacity for monitoring fine-scale sedimentation resulting from dredging operations.
