Comment on “A note on salt intrusion in funnel-shaped estuaries: Application to the Incomati estuary, Mozambique” by

A comment is provided on the paper by Brockway et al. (2006. A note on salt intrusion in funnel-shaped estuaries: application to the Incomati estuary, Mozambique. Estuarine, Coastal and Shelf Science 66, 1–5) on a simple method to determine the salt intrusion in the Incomati estuary. Although this method is able to describe the salt intrusion in the Incomati reasonably well with only limited information, it is demonstrated that with the same data, but a more up-to-date methodology, a better and generally applicable equation could have been obtained.
