Flexible flow deflectors against local scour at bridge piers

In order to explore the potential application of flexible flow deflector in engineering, experiments were conducted to study the countermeasures against bridge pier protection. A three-deflector structure was proposed to improve the efficiency of reducing scouring depth at bridge piers, including one body and two wings. The performance of the proposed three-deflector structure was subjected to some preliminary laboratory tests, and satisfactory results were obtained.
