HYDRAULIC RISK ASSESSMENT IN ARCHAEOLOGICAL SITES SUPPORTED BY AN INTEGRATED DIGITAL SURVEY – CFD (COMPUTATIONAL FLUID DYNAMICS) MONITORING APPROACH

Understanding how waves and currents interact helps us comprehend physical processes occurring in a coastal environment. In the present work, waves and currents were reproduced in the laboratory and flow velocities were measured. Results showed that the superposition of waves induces a cyclic enhancement or suppression of near-bed turbulence, and, depending on current velocity, wave orbital velocity, and bed roughness, waves can alter the current velocity, following highly nonlinear patterns.
