Contributor Velsink, H. (mentor) Abraham, G. (mentor) Faculty Civil Engineering and Geosciences Department Hydraulic Engineering Date 1989-02-01 Abstract In an estuary, the confluence of fresh water of upland rivers with salt water from the sea gives rise to a complex regime of flow pattern due to the difference in densities of the two liquids of about 2.5%. Vhen the estuary is stratified, the heavier salt water which dives underneath the lighter fresh water extends as a long wedge far into the upstream. The amount of saline water brought in by the density current into an estuary can be much larger than the tidal filling, when the freshet dis charges are high compared to the tidal prism. Density currents play a major role in the hydrodynamics of a harbour basin located at the mouth of an estuary The Port of Cochin on the west coast of India is located inside a natural lagoon with a large monsoon discharge passing through its channels. The saline water which enters the deep navigation channels brings in a large amount of silt from the sea resulting in heavy siltation. This thesis deals with the density currents at Cochin and presents the results of a desk study made with the objectives 1. to analyse the hydrodynamics of density currents in general with particular reference to the local situation. 2. to derive the siltation pattern from it and make a first order estimate and 3.to suggest solutions and make recommendations for furhter study.
