Shiau, B.S., Yang, C.L. and Tsai, B.J., 2007. Experimental Observations on the Submerged Discharge of Brine into Coastal Water in Flowing Current. Journal of Coastal Research, SI 50 (Proceedings of the 9th International Coastal Symposium), 789 – 793. Gold Coast, Australia, ISSN 0749.0208 In assessing the coastal environment impact effect, experimental observations were conducted in the towing water flume to investigate the effect of flowing current speed on brine water from desalination plant discharging into homogeneous, two-layer, and linear density stratification coastal waters. The submerged discharge of brine water forming the negative buoyant jet, were observed by applying the Charged Coupled Detector to grab the laser light sheet illuminated image of the brine jet. Runs for different discharging densimetric Froude numbers and ambient water current flow speeds were executed. Proper scale variables are found and used as characteristic parameters. For still or flowing homogeneous ambient water, the scaled terminal height of the submerged brine discharge grows as increasing the discharging densimetric Froude number. Increase of the flowing current speed reduces the submerged brine discharge terminal height. The density interface between two layers of ambient water inhibits the terminal height growth of the brine discharge. And the flowing current advects the brine discharge in downstream along the density interface. In the linearly stratified ambient water, the log function form of scaled inverse of flowing current speeds is found in proportional to the log function forms of scaled submerged brine discharge terminal height and attached length, respectively.
