FLOW MEASUREMENT AROUND DIFFERENT TYPES OF BRIDGE PIERS USING ACOUSTIC DOPPLER VELOCIMETER (ADV)

OpenAlex English

The effective management of water resources is a critical global objective, necessitating the construction of hydraulic structures to mitigate the adverse effects of water and ensure its efficient use. Among these, bridges are prominent engineering solutions. The presence of bridge piers, however, inherently alters the natural flow structure, creating complex hydrodynamic interactions. Consequently, a central challenge in hydraulic engineering is to determine the most suitable pier type and configuration that minimizes these disturbances for a given stream regime. To address this challenge, the present study conducts a systematic investigation through controlled laboratory experiments, comparing bridge piers of varying geometries and sizes under consistent hydraulic conditions. The results demonstrate that both the geometry and configuration of the piers significantly influence the flow structure, even when the net flow passage width is held constant.
