Erosion of mud/sand mixtures
Helen Mitchener,Hilde Torfs +1 more
TL;DR: In this article, the authors investigated the relationship between the erosional properties of combined mud and sand sediments, and found that adding sand to mud, or vice versa, increases the erosion resistance and reduces the erosion rates when the critical shear stress for erosion is exceeded.

A conceptual framework for the erosion behaviour of sand-mud mixtures
TL;DR: In this article, a conceptual framework for the erosion behaviour of sand-mud mixtures is proposed and validated with data from field and laboratory experiments based on appropriate parameters for cohesion and network structure.

Incision and morphologic evolution of an alluvial channel recovering from hydraulic mining sediment
TL;DR: In this paper, the lower Bear River channel morphologic readjustment from the avulsion was both progressive and episodic, and the cross-section shape of the channel narrowed and deepened steadily from 1930 through the mid-1970s.

Determination of the Critical Erosion Threshold of Cohesive Sediments on Intertidal Mudflats Along the Dutch Wadden Sea Coast
TL;DR: In this paper, the bed shear strength on an intertidal mudflat bordering salt marshes along the Dutch Wadden Sea coast was determined by means of an in situ erosion flume (ISEF).
Journal ArticleDOI
Evaluation of a linear bank erosion equation
TL;DR: In this paper, field surveys and aerial photographs were used to measure the rate of migration of a bend of the Brandywine Creek near Chadds Ford, Pennsylvania. And the data indicated that rates of bank migration are linearly related to the magnitude of the near-bank velocity.

Concept Of Critical Shear Stress In Loose Boundary Open Channels
TL;DR: In this article, the problem of defining critical flow condition associated with the initial instability of bed material particle has been studied in relation to existing concepts and the data has been collected and analyzed to indicate that a distinct condition for the beginning of movement doe not exist.

Resistance of selected clay systems to erosion by water
TL;DR: In this article, the authors determined the rates of erosion of selected clay systems by subjecting molded samples to a uniform erosive force and found that increased concentrations of clay minerals generally induced greater stability.

Temperature effects in alluvial streams
TL;DR: In this paper, the effects of water temperature on sediment discharge close to the bed (bed-load discharge), and on bed roughness and geometry in alluvial, open-channel flows were investigated.
