Short summary
Boulder bars are a common form of riverbed morphology which can be affected by outburst flood. However, few studies have focused on boulder bars' formation process and development characteristics during landslide dam failure. In this paper, eight groups of dam failure experiments were carried out to study the development and geometry characteristics of boulder bars during and after dam failure. Moreover, the relationships between geometry parameters of boulder bars are investigated.
