Short summary
This study has the aim of reviewing the dynamics of debris flow impact against rigid structures and providing a new simple formulation to predict peak thrust. The proposed equation differs from other formulations because it takes into account flow characteristics, material properties, and barrier dimensions. The developed model is sufficiently capable of predicting measured force during the laboratory tests.
