Water flow pressure changes on circular and square bridge piers under increasing velocity floods

Resistance to flood is a critical parameter affecting the design of the bridges. Typical design process would convert the flood loading in to a static force which can not reflect the full effect of flood loading on piers of different shape. Therefore it is important to investigate the effect of flood loading on piers of different shape. This work simulates the flooding effect on the piers using a finite volume method in ANSYS Fluent. The pier is modelled as a column with a square cross section or a circular cross section.
