skimming weir in the tidal basin. Constant salinities are maintained at this end to represent the ocean end
of the idealized estuary during each test run. Constant freshwater is discharged into the estuary at the
other end of the channel. The flume is operated for a sufficiently long time to achieve mean steady state
conditions for salinity intrusion.
