a January; b March; c May; d July. A and PF at the top of the Fig. 5.5. represent, respectively, Arambare

proposed for salt balance studies in well mixed narrow estuaries but it is being applied as well for broad partially stratified systems (Fischer et al. 1979). The dispersion
coefficient Kx (Fig. 5.7b) increases exponentially towards the mouth varying in the
southern part of the lagoon from 2000-5000 m 2 S-I. These are extremely high values
compared to those presented by Dyer (1973), for instance. Comparable Kx values have
been determined for the Gironde (Bonnefille 1978), Rotterdam Waterway (Winterwerp
