Proposal of a water shallow tank for long and capillary-gravity waves based on a numerical simulation

In the scientific literature, wave tanks are widely used to reproduce and investigate the behaviour of surface waves and,particularly, the long waves. Most experiments are aimed to study the performance of wave energy converters. In orderto analyse the basic properties of capillary-gravity waves (reflection, refraction, and diffraction) and related phenomena asinterference, resonance and Doppler effect, ripple tanks are more suitable. In this paper, an instrumented shallow tank wasdesigned to generate and observe both ripples and long waves. To validate the tank model, some numerical simulations wereperformed with an appropriate software, taking into account all the two-dimensional effects, including boundary and edgeeffects, relaxation and damping
