Abstract: In lake-wetland interfaces, density currents have a significant environmental impact and play a relevant role in the transport of nutrients and pollutants. These currents are driven by a hydrostatic imbalance of two adjacent fluids with density variations in temperature, dissolved materials, or suspended compositions, propagate in a predominantly horizontal direction. While the hydrodynamics of density currents propagating over smooth and rough horizontal boundaries is considerably well understood, its interaction with vegetation or other bluff bodies is less studied. Addressing an identified research need, the present work is aimed at characterizing the generation and propagation of density currents within an array of vertical cylinders. The research methodology included laboratory and numerical work.
