“…The results revealed that, compared to the horizontal bed, the bed slope did not increase the energy dissipation rate of countercurrent jets but decreased the return flow length and upstream water level. Sharoonizadeh et al (2022) studied the hydrodynamic features of counterflow jets in an abruptly expanding channel. The results revealed the good performance of the counterflow jets in preventing flow instability associated with abruptly expanding stilling basins.…”

The present experimental study analyzes the effects of lateral jet flow (LJF) in a stilling basin with abruptly expanding channels on the stabilization and the significant characteristics of spatial hydraulic jump. The experiments were carried out with three different inflow Frude number (8.77,9.56,and 10.87), three different distances of the LJF from the abruptly expanding channel (0 m, 0.25 m, and 0.5 m), and one and two LJF (i.e., the number of active orifices in the LJF system). According to the results, both distances of the LJF from the narrow channel and the number of LJF improve the hydraulic jump's stabilization and flow pattern enhancement in the tailwater channel. Additionally, the average sequent depth and the spatial jump length decreased by 14 and 20%, respectively, compared to no LJF. Also, using LJF increases relative energy dissipation by 12.45% on average.
