This Study Presents The Turbulent Flow Field In Submerged Plane Wall-Jets And The Gravel-Bed Stream In Response To Injection And Suction From Wall. In Submerged Wall-Jets, The Rate Of Decay Of Jet Velocity Increases With An Increase In Injection And Decreases With Suction. The Wall Shear Stress Decreases In Presence Of Injection; Whereas It Increases With Suction. The Two-Dimensional Reynolds Averaged Navier-Stokes (Rans) Equations Of A Steady Turbulent Flow Are Theoretically Analysed To Compute The Velocity And Reynolds Shear Stress Distributions In The Fully Developed Zone Of Submerged Wall-Jets Subjected To No-Seepage, Injection And Suction. Analysis Of Third-Order Moments Of Velocity Fluctuations Reveals That The Inner-Layer Of Jet Is Associated With The Arrival Of Low-Speed Fluid Streaks Causing An Effect Of Retardation; While The Upper-Layer Of Jet Is Associated With The Arrival Of High-Speed Fluid Streaks Causing An Effect Of Acceleration. The Distributions Of Kurtosis Reveal High Intermittencies Of Turbulence. The Streamwise Turbulent Energy Flux Transports Towards The Jet Origin Within The Shear Layer Of Jet; While It Travels Streamwise Within The Inner-Layer Of Circulatory Flow. The Turbulent Energy Budget Indicates That The Turbulent And Pressure Energy Diffusions Oppose Each Other. The Quadrant Analysis Of Velocity Fluctuations Suggests That The Inward And Outward Interactions Are The Primary Contributions Towards The Reynolds Shear Stress In The Inner- And Outer-Layer Of Jet, Respectively, Although Injection Induces Feeble Ejections In The Vicinity Of The Wall. In Free Surface Flows Over A Gravel-Bed, The Turbulence Correlation Coefficient Decreases In Presence Of Injection And Increases In Suction; While The Turbulent Diffusivity And The Mixing Length Increase In Injection And Decrease In Suction. Analysis Of Third-Order Moments Of Velocity Fluctuations Reveals That The Ejection Phase Is Prevalent In The Entire Flow Depth Associated With The Arrival Of Low-Speed Fluid Streaks. The Turbulent Energy Budget Indicates That The Turbulent Dissipation Lags From The Turbulent Production, Whereas The Turbulent And Pressure Energy Diffusions Have Opposing Trends. The Quadrant Analysis Of Velocity Fluctuations Suggests That The Ejection And Sweep Events Are The Primary Contributions Towards The Reynolds Shear Stress And Ejections Dominate Sweep Throughout The Depth.
