Define turbidity as it relates to a dredging operation?
Turbidity is defined as the re-suspension of bottom sediments into the water column which appear sometimes as a “visual” plume in the water column or an increase in the turbidity in the area of the dredge above residual or “background” levels. It is measured in NTU’s or nephelometric turbidity units, and is a measure of light (optic property) passing through a given length in a column of water. All Ellicott dredges are designed with standard features and optional features to keep turbidity to a minimum.
