Variability of sediment processes around a tidal farm in a theoretical channel

Sediment transport plays a crucial role in coastal ecosystems and is one of the least known parameters high energy sites. The recent development tidal projects challenges scientific community to better understand this natural phenomenon interactions with turbines. Using MIKE21/3 software from DHI, benchmark for sediment model was developed simulations without farm idealised two three-dimensional channels. Results reveal that 2D approach sufficient regional scale morphological assessments, however 3D models allow closer examination influences around farm. Differences calculating rates based on approaches after Engelund & Fredsøe Van Rijn formulae illustrate degree uncertainty modelling rates. also show they are sensitive mesh resolution equilibrium conditions more stable non-equilibrium bed level change Tests have demonstrated using physical characteristics than Rijn, accentuating necessity evaluate field data before making choice model.
