MODEL HARBOUR SEICHING COMPARED TO PROTOTYPE DATA

W.A.M. Botes, K.S. Russell, P. Huizinga

Abstract


Since 1978 a finite-difference numerical model based on that developed by Leendertse and adapted for resonance studies (Russell and Huizinga, 1978) has been applied to investigate harbour resonance in Table Bay Harbour and several other South African ports. During April 1981 three long-wave recorders were installed in the cooling water intake basin of the Koeberg Nuclear Power Station to determine the occurrence and magnitude of the long waves and to measure the corresponding response of the basin. Koeberg is situated on the west coast of South Africa, 30 km north of Cape Town and is exposed to the approaching cyclonic weather systems which experience has shown to be associated with the occurrence of long waves. An example of an approaching low pressure system with the location of Koeberg is shown in Figure 1.
