Abstract

Results are presented from a series of laboratory model studies of flushing of saline water from a partially- or fully-closed estuary mouth. Experiments have been carried out to determine the response of the trapped saline volume as a function of the fresh water river discharge Q, the density difference Delta rho between the saline and fresh water and the estuary bed slope alpha. Flow visualisation and density probe data confirm that the transient behaviour of the plume can be represented well by the use of length and time scales Q(2/5)/(g')(1/5) and Q(1/5)/(g')(3/5) respectively, where g' = g(Delta rho)/rho(0) is the modified gravitational acceleration and rho(0) is the density of the freshwater now.
