Airflow over a square cross-section at high Reynolds numbers and different angles of incidence is investigated with the aim of providing deeper insight into wind actions on elongated structures and, in particular, tall buildings. The flow around bluf

Erosion and flooding are the main threats for most coastal regions. Nature-based solutions, such as coastal vegetation (CV) fields, have received significant attention in recent years because they effectively dissipate wave energy while maintaining b

A modification of the immersed boundary method is presented, using the discrete-forcing concept, for the large-eddy simulation of turbulent flows over coastal/fluvial beds. The method was adapted to be compatible with the usual surveying practice to

In the present work the applicability of an extended Boussinesq-type model in simulating wave propagation over submerged porous breakwaters, as well as predicting the velocity distribution inside them was studied. The basic solver is able to reproduc
