Wave and hydrodynamics modelling in coastal areas with TELEMAC and MIKE21

Abstract—Wave and hydrodynamics modelling in coastal areas is nowadays an indispensable tool for both research and engineering/environmental design. The selection among the various available models is equally essential and should be done cautiously, taking into consideration both the models’ capabilities and the actual modelling needs. In the above context, results of ongoing research on the comparison between TELEMAC and MIKE21 are presented in this work. The test study area is located near the Port of Brindisi in South Italy. TELEMAC simulations were performed using TOMAWAC for wave propagation and TELEMAC-2D for the hydrodynamics; MIKE21 simulations were performed using the MIKE21-SW and MIKE21-HD modules respectively. Model output is compared on the basis of wave/current fields and wave propagation along linear trajectories from the offshore to the shoreline; analysis shows an overall satisfactory agreement between the two models
