Abstract of the proposal

The aims of this project are:

1) to explore the dynamic interaction between seawater and groundwater by analysing the tidal cycle and the groundwater level in geologic formations near the coastline in Hong Kong, an area which is critical for the environment and has many important engineering structures, and

2) to estimate hydraulic parameters of some typical geologic materials along coastline by considering the fluctuations of groundwater levels caused by tidal effects.

This research will provide important geologic and hydraulic information for the coastal environment and engineering practices such as site investigation, dewatering system design, and slope stability analysis in coastal areas in Hong Kong.
