The purpose of this research is to adapt and improve existing two-dimensional numerical
tidal models so that they can cope with regions where the tide falls and rises to uncover and
cover inter-tidal banks without incurring numerical shocks which may be caused by the
discretization of time and space.
This thesis presents a review of current practices in the numerical modelling of flooding and
drying banks in two dimensions. A two-dimensional depth-averaged numerical model has
been written and is presented. It is used as a tool with which to investigate various existing
algorithms which represent the physical process of the wetting and drying of intertidal zones.
An alternative method with which to represent the moving boundary has been developed.
This method is free from disturbances usually caused by the implementation of a moving
boundary in such a numerical scheme.
A 2NM numerical model of the Wash, U.K., is run to provide hind-cast tidal data pertaining
to a particular site and period. A field programme is established to provide validation data
for the model.
Finally, conclusions from the programme of research are drawn.
