Short summary

A new type of spillway structure with lateral contraction was proposed to distribute debris flows after the check dam storage filled up. Experiments were performed to investigate debris flow movement, the scour feature, and some related hydraulic characteristics of debris flows under this new structure. The results indicate that this type of structure can help extend debris-flow nappe, dissipate flow energy, and reduce the scour depth downriver of a check dam.
