Abstract: The temporal effect of hydrograph on local scour depth is investigated under clear-water scour condition. By analyzing the characteristics of scour-depth evolutions at bridge piers for different rising hydrographs, a ...

Abstract: Experiments of bridge pier scour are carried out under steady and unsteady clear-water scour conditions with uniform and nonuniform sediments. Around the pier nose, the sediment size variation of surface bed materials is ...

Abstract: A water quality and ecosystem model is developed to simulate nutrients, heavy metals, and aquatic plants in the Erh-Chung Flood Way wetland in Taiwan. A sediment system was incorporated into the model. The RMA2 and WASP/EUTRO5 ...

Abstract: Hydraulic experiment courses in engineering education usually require students to follow a “standard procedure.” Students are expected to learn the underlying theories through manipulating the equipment, observing the ...

Abstract: An understanding of bridge scour mechanisms during floods in a fluvial river is very important for cost-effective bridge foundation design. Reliable bridge scour data for flood events are limited. In this study, field ...

Abstract: Failures of bridges that span a waterway often result from scour and channel instability near the bridge foundations. The Houfeng Bridge, which crosses the Da-Chia River in central Taiwan, collapsed in the 2008 typhoon ...

Abstract: A two-dimensional (2D) layer-averaged model was previously developed to simulate turbidity current characteristics and its sluicing in reservoirs. It was calibrated and validated using the data from a down-scale physical ...

Abstract: Piers with back-to-back stems or columns and piers for which part of the foundation becomes exposed as a result of the development of scour over large periods of time or because of severe flood events are fairly common at ...
