Synopsis
This paper describes results of various experiments conducted over the diffuser
section of a laboratory representation of a long sea outfall. Detailed
measurements of instantaneous riser salinity and velocity for various
experimental configurations and under steady and unsteady flow cycles are
presented. Findings are discussed with reference to relevant previous
investigations. In particular, it is demonstrated that mixing from the intrusive
salt wedge stratification front in the main pipe is evident from discharging risers
well upstream of the first intrusive riser. This has some implication to
application of the well established riser purging criterion at the design stage.
