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 sediment, and describes the implementation of a morphological updating scheme which incorporates...

Biography

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 MSc on 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.
