Cohesive Sediment Erosion.

Abstract

This report consists of three chapters: Chapters 1 and 2 deal with erosion test devices and field instrument assemblies, while Chapter 3 is an analysis of published erosion rate of bed shear strength data in an attempt to establish a functional link between the characteristic erosion rate constant (defined as the slope of the erosion rate-bed shear stress plot). A wide range of erosion test devices has been used both in the laboratory and in the field in the effort to further elucidate the phenomena of cohesive sediment erosion. They differ in configuration and flow geometry, size, mechanisms of generating flow, operation protocol, and measurement methodology. These devices are further complemented by various custom designed field instrument assemblies, which provide valuable prototype data for model calibration and validation. The report reviews six categories of laboratory erosion test devices and eight categories of field devices/measuring assemblies. For each category, a representative device from the literature is described with a view to illustrating its salient features and typical test results. Similarly, the field instrument assemblies are individually described, including a brief discussion on typical field results. The description is confined to a documentation of the suite of equipment with incidental comments on their merits without an effort to compare them on a relative basis.
