  • Seiching in Cockburn Sound
    Seiching in Cockburn Sound by Emma Molloy Department of Environmental Engineering University of Western Australia November, 2001 Abstract A seiche is the oscillating response of an enclosed or semi-enclosed water body to external forcing, in order to return the system to equilibrium. The disturbances that cause seiches can be a variety of atmospheric and water-based mechanisms, including wind, air pressure, waves and tsunamis. In semi-enclosed micro-tidal water bodies such as Cockburn Sound, the prime mechanisms driving seiches are changes in wind speed and direction (Luettich et al, 2000). Cockburn Sound is a north-south oriented oval-shaped harbour system located 35 km south of Perth, Western Australia. It is enclosed on all sides by land, with a large opening on the north-east side. This opening facilitates water exchange to the north of Cockburn Sound. However, to the west there are reefs restricting flow. Therefore, the seiches oscillate between Mangles Bay in the south of Cockburn Sound and Fremantle. This is considered to be a semi-enclosed (“open”) system. Cockburn Sound houses a large variety of industry, as well as marine and bird life, and is used by the public for recreation. The seiches in Cockburn Sound have an impact on all of these areas. The primary effect of seiches is in influencing the mixing and flushing of the system, especially of contaminants released by the industries. Water level data were collected from Mangles Bay at the southern end of Cockburn Sound during May 2001. Water level data were also available from previous studies in this area.

In 1964 the timber pylons and dolphins were demolished with explosives and the steel nets were cut and dropped onto the seabed (Jeffery 1988).
