Giles Lesser has recently joined the U.S. Geological Survey (USGS)'s Coastal and Marine Geology Program as a visiting scientist to work with Guy Gelfenbaum and Chris Sherwood on sediment-transport and morphological modeling.

Stationed in Menlo Park, CA, Giles is visiting from Delft Hydraulics in the Netherlands, where he works as a researcher and advisor in Delft Hydraulics' Marine and Coastal Infrastructure section. Giles will work with Guy, Jessica Lacy, Peter Ruggiero, and Laura Kerr as they model estuarine sediment transport and morphological change in Willapa Bay, WA, to help the U.S. Army Corps of Engineers and the Shoalwater Bay Tribe address severe erosion of tribal lands.

Giles will work with Chris, Jessie, and John Warner to model Grays Harbor, WA, and to help develop test cases for comparison and evaluation of sediment-transport models as part of the Community Sediment Transport Project.

Giles' experience with Delft Hydraulics has covered a range of coastal-engineering applications, from wave-penetration and ship-motion studies to the application and further development of Delft's numerical morphological models. Before going to study in Delft, Giles worked for several years as a civil engineer for a local authority in his home country, New Zealand. Giles has a Bachelor of Engineering degree from the University of Canterbury in Christchurch, New Zealand, and a Master of Science degree in coastal engineering from the International Institute for Infrastructural, Hydraulic and Environmental Engineering (IHE) in Delft, the Netherlands. Since completing his thesis on the inclusion of sediment transport in the Delft3D hydrodynamic model, Giles' morphological modeling experience has included developing several physical morphological models, addressing harbour-siltation problems, and modeling morphological changes around manmade structures.
