Geophysical Studies In Setiu Lagoon-Estuary System

The study area is a shallow , bar-built , partially mixed lagoonestuary system , which undergoes changes in its pat tern of movement and mixing due to meteorological and river run-off changes. The Setiu estuary is of primary oceanographic interest since it is one of the large estuaries of the Te...
