Short Description

Grade level: High (9-12), Under graduate (13-16)

Statement: Sheet Flow

Abstract: Sheet flow style bed load transportation with colored marker stones. In this form of bed load transport a portion of the bed moves as a unified sheet.

Theory

Bed load transportation is a function of the fluid force per area, or shear stress on the stream bed. Shear stress is proportional to the specific weight of the fluid, the depth and the surface slope of the fluid. The frictional resisting force is proportional to the specific weight of the sediment and the diameter of the sediment.
