Plunge pool scour is an important phenomenon as it involves risk of structural damage due to high velocity impact jet. The paper analyzes the pressure field created below the scour hole due to plunging jets. An experimental study was carried out at the Hydraulic Laboratory of the University of Pisa, Pisa (Italy). The pressure below the scour hole depends on several parameters, such as jet discharge, jet angle, tailwater level, densimetric Froude number, granulometric properties of the basin material. Experiments were carried out to measure the pressure at different grid points and develop relationships to predict the pressure field below the scour hole as well as the dynamic equilibrium configuration of the scour hole surface.
