Abstract: Emergent vegetation governs a wide range of physical, chemical and geomorphological processes in water bodies. Mass transport is dominated by vegetation elements, through stem-related energy production and vortex generation. These assumptions are analysed using a novel experimental dataset, able to characterise velocity and concentration fields at a comprehensive range of relevant scales. LIF and PIV experiments were performed in a random cylinder array (Corredor-Garcia, 2023), designed to mimic the stem diameter distribution and density of real vegetation. The objective of the experimental campaign was to obtain complementary concentration and velocity fields to determine the main hydrodynamic drivers of dispersion and study the main assumptions underpinning current models of mass transport in cylinder arrays.
