“…The time scale associated with significant cooling by surface heat exchange can be shown to be at least an order of magnitude greater than a tidal period. Therefore the temperature distribution which results from this surface exchange can be represented by the tidal averaged equation:- (5), and was found to agree well at all points except close to the source, where the assumptions on which the two solutions were based differed slightly.…”

The object of this case study was to predict the likely degree of pollution resulting from the discharge of heated water from a proposed LNG plant into the sea (Figure 1). The expected thermal loading was 40 m-Vs at a temperature of 10°C above the natural ambient sea water temperature. The investigation was required to provide data for an ecological study to determine the possible impact of the plant on the coastal and marine environment. Information on tide levels, tidal currents, salinity, sea temperature, wind strength and direction was obtained in a general survey programme which had already been commissioned. These data provided vital information on seasonal variations in marine conditions and further local information was obtained from short intensive hydrographic surveys. The data were analysed to yield a simplified description of the tidal and wind induced currents and suitable values of mixing parameters for use in two numerical models. The first dealt with the "near field" processes of the spread of a buoyant layer of heated water under the convecting influence of the tidal currents. The second model simulated the "far field" processes which give rise to a general increase in the temperature of the sea in the region.
