Channel Design Emphasizing Fine Sediments and Survey of Alluvial Channel Sediment Transport
This chapter presents a discussion of earthen channel design, particularly earthen channels in fine‐textured materials. It explores the alluvial or moveable bottom implications on channel hydraulics, sediment transport, and channel design. Given a flow rate and low sediment transport rate, one can develop preliminary channel designs to accommodate sediment transport. Early approaches to sediment transport exploited the concept of excess shear, as manifested in a series of sliding layers. The chapter presents Einstein's work in detail and subsequent approaches for bedload and suspended load sediment transport. The Shields work remains useful for predicting incipient motion and revetment sizing. The chapter analyzes the incipient motion of sediments and riprap specification for given conditions and aims to refine a design criterion based on shear stress for fine sediments. It also aims to assess the nature and type of alluvial bedforms and to model stage–discharge of alluvial channels.
