In the mountainous region of Vietnam, in the flood season, the phenomenon of debris is very common, causing danger to bridges. Debris affects the scour morphology at bridge piers, thus increasing the bridge failure potential. During the flood in October 2017, the Thia Bridge collapsed in Yen Bai, Vietnam. After the survey, the large trees attached to the piers are believed to be the main cause of this bridge collapse. Debris accumulation countermeasures can be classified into two main categories, including structural and non-structural methods. So, this paper presents details of these methods, and their applicability in Vietnam.
