Interpretation of Sediment Transport Modelling Results in the Context of the Known Unknowns – a Case Study N ear Great Yarmouth, UK

This paper seeks an answer to the following fundamental questions:

The answers are sought through consideration of effects due to a large harbour development on the east coastline of the UK at Great Yarmouth (Figure 1 refers) in a region where littoral processes are complex. The studies reported here were commissioned by Bourne Leisure Limited – owners of the Hopton Holiday Park located to the south of the harbour.

The first major development of a harbour at Great Yarmouth took place in the early seventeenth Century. The River Yare provided a safe haven adjacent to its entrance due to a right angled bend (Brush Bend) in the river near its outlet to the sea. The sand spit between the river and the sea was essentially reclaimed for port infrastructure but the harbour remained located in the river. Training walls were built to fix the river entrance and improve navigable depths as shown on Figure 2 – these walls extended in the 1960s are now as shown in the figure.
