Abstract: Tidal lake inlets in N. S. W. have variable hydraulic efficiency along their lengths. In many cases, heavy entrance shoaling at the ocean end causes high tidal energy losses, and largely determines the tidal volume exchanged to the lake hasin. The extent of this entrance constriction varies markedly from inlet to inlet, and at some inlets is highly variable through time, under the influence of meteorological processes. Field data from a range of inlet types is presented to demonstrate that the hydraulic response of the inlets is similarly varible. Through comparison of data from inlets of differing degrees of constriction, it is apparent that construction of works at an inlet entrance to improve navigability may significantly alter the inlet and lake hydraulics if the inlet had previously been heavily shoaled at the ocean end.
