A field evaluation of the formative conditions, wavelengths and heights of alternate bars in alluvial channels
Abstract
dc:descriptionThis study investigates the fluvial dynamics of straight natural stream channels. In particular, this experimental field study quantitatively assesses: (1) six experimentally derived formulas that predict the conditions for alternate bar formation and equilibrium bar dimensions, and (2) a physically-based nonlinear mathematical theory of alternate bar formation under unsteady natural flow conditions within a straight alluvial stream (Tubino 1991). The study site is an artificially-straightened section of the Embarras River located approximately 16 km south of Champaign, Illinois. Data were collected on channel form, gradient, alternate bar dimensions, and flow conditions over a two-year study period.
