Numerical investigation of the head and unsteady flow characteristics of a dredge pump loading high-concentration sands

The head of a dredge pump is an important performance parameter and a strongly fluctuating head may affect the operating stability of the pump unit. The IADC Young Author’s Award paper analyses unsteady characteristics of pump performance to improve control of the dredge pump.

The IADC Young Author Award-winning paper verifies the agreement between the theoretical calculations for a new toothless draghead and the real situation when the draghead is being used.

Important Engineering Properties of Geotextile Sand Containers
Important Engineering Properties of Geotextile Sand Containers

No proper design guidelines based on sound science are available for the design of GSC structures. This IADC Young Author Award paper describes on-going research which aims to remedy this.

Biogeomorphological Interactions on a Nourished Tidal Flat: Lessons Learnt from Building With Nature
Biogeomorphological Interactions on a Nourished Tidal Flat: Lessons Learnt from Building With Nature

Worldwide the total area of tidal flats is decreasing as a result of sea level rise, subsidence by gas extraction and erosion initiated by artificial constructions. This IADC Award winning paper examines whether nourishment programmes might be part of the solution.
