Geographic Information Systems for Modelling Sediment Transport and Desposition in Harbours

For his discussion of mathematical models to manage and analyze erosion and despositions along the coastline, an IADC Young Authors Award was presented to Chakib Biar at the CEDA Dredging Days in Morocco, October 2002.

Dredging Stiff to Very Stiff Clay in the Wielingen Using the DRACULA® System on a Hopper Dredger
Dredging Stiff to Very Stiff Clay in the Wielingen Using the DRACULA® System on a Hopper Dredger

Dredging stiff clay is notoriously difficult. A newly patented system using high pressure waterjets in the hopper dredger's draghead has solved several operational problems. For his description of this innovative technique, the author was presented with a 2002 IADC Award at the PIANC Conference in Sydney, Australia.
