A study on the energy dissipation of apron setting on the main deep trough of river bed: 2D unsteady flow simulations: Chihshang bridge in Taiwan as case study

This study uses SMS-2D unsteady flow model to simulate energy dissipation of apron setting due to bow wave around the bridge pier on the main deep trough of ChihShang Bridge in 100 years return flood peak flow, on the downstream BeiNan River in Taiwan as case study. Further, the topic of this study is to evaluate location-oriented scour likely result in accelerated erosion of critical piers by different apron settings and designed sizes in case of excessive cost, thus, providing reliable information and references for bridge engineers.
