== Can I model bridge piers explicitly in 2D using very small cells? ==
It isn't recommended to explicitly model bridge piers by blocking out the pier faces in TUFLOW, or any hydraulic modelling software based on solving Shallow Water Equations(SWE),. dueExplicitly torepresenting thesmall-scale meshobstructions, resolutionsuch requiredas andbridge thepiers, 3-dimentialityin ofTUFLOW therequire flowextremely fine mesh resolutions and calibration of turbulence aroundmodel theparameter piers(see).
 
due to the mesh resolution required and the 3-dimentiality of the flow and turbulence around the piers.
 
 
This results in significantly higher computational costs and often fails to accurately capture the complex flow phenomena. Additional head losses caused by drag characteristics are better represented through empirical coefficients rather than direct modelling.
