The authors regret that the following errors appeared in this paper when it was published in Proceedings of the Institution of Civil Engineers – Engineering and Computational Mechanics 165(2): 131–145.
In section 2 on p. 132, in the sentence ‘In the experiment described here, the inner cylinder was filled with salt stratified water at room temperature (25°C) with a buoyancy frequency of N ∼ 0·44/s', the buoyancy frequency should be N ∼ 0·66/s.
In section 3.3 on p. 135, N ∼ 0·44/s should read N ∼ 0·66/s.
Throughout the paper, the units for salinity should be ppm, not g/l.
Table 2, presented on p. 139, is incorrect and is a repeat of Table 1. The correct Table 2 is published here.
