Abstract: The discharge of wastewater into coastal waters, which forms the single jet or multiple jets, is subjected to the coastal dynamics (i. e. , crossflow and waves). The characteristics of dual jets vertically discharged into a wavy crossflow are investigated in this study, by use of the particle image velocimetry (PIV) technique as well as a large eddy simulation (LES) model. The results show that, (i) the wavy crossflow leads to the deflection and swaying of the dual jets, (ii) the leading jet has a shielding effect on the rear one, (iii) the wave effect leads to further deflection of the jet body, (iv) the counter-rotating vortex pair (CVP) structure is a significant feature of dual jets in the wavy crossflow environment
