About This PhD Project

Project Description

Gravity current is frequently encountered in natural (e.g. saltwater intrusion in estuary) and men-made environment (e.g. mining solution; desalination). The motion and dilution of gravity current is very important to the environment and ecology of the receiving water bodies. For example, produced water from mining solution is hypersaline which could harm fauna and flora of ambient water bodies. Therefore, rapid dilution is of importance for minimizing such adverse effect. Boundary condition plays an important role on the dilution process of the gravity current.

Students studying this project will therefore investigate the effect of the bottom bed roughness on the motion, mixing and dilution of the gravity currents by using laboratory experiments or/and numerical modelling simulation.
