Faculty Civil Engineering and Geosciences Department Hydraulic Engineering Date 1986-01-01 Abstract It is the aim of this note to give a simple introduction to the method as used by Galappatti (1983) to derive a depth-integrated model for suspended transport. Contrary to other depth-integrated models (see e.g. Latteux and Teisson, 1985) this model is directly based on the 2D convection-diffusion equation (see e.g. de Vries, 1981) including the boundary condition near the bed. No extra empirical relation for deposition/pick-up rate near the bed is necessary. This note will concentrate on a schematic case in order to clarify the solution method as good as possible. In this report the following topics will be discussed: Chapter 2: The depth-integrated model will be derived using an asymptotic method Chapter 3: Some important functions and a characteristic adaption time (for the average concentration) will be derived in an analytical way. Chapter 4: Remarks will be made concerning more general cases (non-uniform conditions) and the validity of the model.
