A study on the model of percolation of debris-flow dam
at the intersection of two rivers |

| Percolation threshold of free
percolation -D model is calculated by renormalization group method. On the basis of this,
a -D model of self-similar percolation is developed. With the model, we explain why the
other side of river is earlier to break than the other places of the dam in many real
cases. Moreover, in the terms of the situation changes of debris-flow dam after the river
is blocked up by debris-flow, the mechanism of debris-flow dam break is discussed..A study on the model of percolation of debris-flow dam
