Abstract: The disposal of dense effluents such as the desalination brine in coastal waters, leads to the formation of turbulent negatively buoyant jets. Inclined discharges are commonly employed to increase the entrainment and thus the final dilution. Several experimental studies have been presented for inclined round dense jets, e. g. Papakonstantis et al. (2011a, b), Lai and Lee (2012), Oliver et al. (2013a), but less experimental data exist for inclined plane dense jets, e. g. Voustrou (2014), Voustrou et al. (2015), Papakonstantis and Mylonakou (2021). Integral models were specifically developed for inclined round dense jets, which take into account either the reduced entrainment (e. g. Papanicolaou et al., 2008; Lai and Lee, 2012) or reduced buoyancy flux (Oliver et al., 2013b) in the rising branch, or explicitly model the loss of mass from the concave side of the jet through the escaping mass approach (EMA) (Yannopoulos and Bloutsos, 2012; Bloutsos and Yannopoulos, 2020). However, integral modeling of plane dense jets has not been attempted so far. In this work, two different integral models, EMA and GM2D, are used to predict the terminal height of the upper boundary of plane dense jets discharged at several angles between 15o and 90o. The predictions are compared to relevant experimental data reported by Voustrou (2014) and Papakonstantis and Mylonakou (2021).
