Abstract
The theory of characteristics is applied to analyze two‐dimensional unsteady flow over a bed of fine sediment. The sediment is assumed to be so fine that suspension is the predominant mode of transport. An additional equation for sediment diffusion is introduced. As a result, the number of characteristics is increased, but the characteristic directions can be determined without solving high‐degree algebraic equations. Results from a one‐dimensional version of this procedure agreed reasonably well with known data.Keywords
