The aim of the study was to give an indication of the accuracy and applicability of one-dimensional salt intrusion models in estuaries in Mozambique. Attention is mainly centered on tidally averaged modeis, although some preliminary testing of a real- time model is included as weIl. Testing of the models is done with data, obtained from a field study in the river Maputo in Mozambique. The results show that, notwithstanding the many limitations, tidally averaged, one-dimensional models can be an indicatory tooI for description of saltintrusion in the estuary considered. Furthermore the study reveals that description of dispersion mechanisms, solely ?n the basis of theoretical considerations, is still not feasible but always needs some sort of empirical relationship. It was found that during preliminary investigation of estuaries more emphasis has to be laid on measuring salinity distributions under varying circumstances in the estuary than on detailed measuring of the geometry.
