Funwave 1.0: Fully Nonlinear Boussinesq Wave Model - Documentation and User's Manual

This report documents the computer program FUNWAVE based on the fully nonlinear Boussinesq model of Wei et al. (1995). The documentation provides a description of the governing equations and the numerical scheme used to solve it. A user's manual is provided and gives instructions on how to use various preprocessors and postprocessors to set up...

Informal Monograph on Riverine Sand Dunes

This report presents an investigation of riverine sand dunes and includes an extensive literature review on the subject. It was concluded that the principal mechanisms responsible for river bed instability, which results in the production of ripples, dunes, etc., are fairly well understood. However, several of the key constituent processes are...

A Numerical Model for Flow and Sediment Transport in Alluvial-River Bends

The principal features of the numerical model developed herein for calculation of flow and sediment-transport distributions in alluvial-river bends may be summarized as follows: i. The secondary-flow strength and the bed topography are uncoupled from the calculation of distributions of lateral shift velocity and streamwise velocity. This is...
