An approach to medium-term coastal morphological modelling - Lesser, Giles

. .

This thesis presents the implementation of fully three-dimensional sediment transport and morphological updating formulations within a proven three-dimensional hydrodynamic flow solver. The thesis briefly discusses the formulations used to model both suspended and bed-load transport of non-cohesive

Résumé :
Documents the development and validation of a three-dimensional sediment transport and morphological numerical model suitable for coastal regions. This book discusses the modelling of both suspended and bed-load transport of non-cohesive sediment, and the aspects of the morphological updating scheme....

Biographie:
Giles Lesser (Wellington, New Zealand, 1970) studied civil engineering at the University of Canterbury in Christchurch, New Zealand graduating in 1991. From 1992 until 1998 he worked as a civil engineer for Wellington City Council where, for a period, he was responsible for the maintenance of the city's many kilometres of coastal defences. In 2000 he was awarded an MScon coastal engineering at UNESCO-IHE. He was employed by Delft Hydraulics from 2001 until 2006. In February 2006 Giles relocated to Melbourne, Australia to finish his thesis....
