Abstract: For hydraulic structures, the process of energy dissipation by means of plunging jets is employed if the physical condition does not allow the use of hydraulic jump stilling basins. The geometry of the jet and its hydraulic characteristics are the main factors affecting energy dissipation, and thus, the structure of its downstream plunge pool. In addition to the geometry of the plunge pool, its material properties and the depth of water within the pool will also influence the hydrodynamic forces and their distributions within the plunge pool. In this paper, experimental investigations of pressure fluctuations within a plunge pool were performed to determine the intensity of hydrodynamic pressures on its bed by falling jets. Rectangular jets issued by orifices of different sizes were used in this study to determine their effects on pressure field within a plunge pool.
