| Summary: | 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 Froude numbers (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, the 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.
