For powerplants to be located along tidal estuaries, the temperatures in the intake and outlet of the cooling-water circuit and the temperature field at the outfall site can be influenced by: (i) the outlet design, affecting the near-field temperature distribution, and (ii) the intake design, provided that temperature varies sufficiently with depth at the point of intake. Further it is necessary to consider (iii) the return of heat, a far-field effect, caused by the reversal of tidal currents. The geometry being a complicated one, item (i) and (ii) require a hydraulic near-field model. Often a mathematical model is the most economical tool to study item (iii). This paper illustrates how a study, involving both prediction methods was performed for the Borssele Powerplant along the Western-Scheldt estuary in the Netherlands.
