This study explores the sediment transport characteristics of bores (generated by dam-break) propagating through emergent vegetation by means of numerical modeling, which is based on the shallow water-Exner equations. Unlike the conventional drag force formula, the vegetation effect was accounted for in our study with a new approach that not only considered the base component of drag force expressions but also the effects of both water surface variations and pressure gradient. The numerical model was then validated against our laboratory data for two cases of sloping movable bed: without and with vegetation. The results showed that the model could accurately capture the water surface fluctuations over the time. Without vegetation, the bores caused erosion around the sloping bed and thereafter deposition, while almost no changes were observed elsewhere. Meanwhile, erosion by the bores with vegetation becomes more significant around the sloping bed, inducing larger deposition (than the case without vegetation) in front of the vegetation. These erosion and deposition phenomena were properly modeled, showing an accurate prediction of the sediment transport characteristics by our model.
