Abstract
Reliable debris-flow modelling requires the coupled treatment of rapid free-surface propagation, variable mixture composition, wet–dry fronts, basal resistance, bed exchange, and grain size segregation. This work presents PyDebrisFlow2D, a depth-averaged Python (3.13.14) solver based on seven conser...
