| Abstract: | In order to strengthen debris flow prevention and mitigation,the fuzzy theory is introduced into the debris flow hazard assessment with the hidden slag debris flow at the Dahuyu valley’s ditches in the Xiaoqinling goldfield area as an example.The hierarchical method is used to analyze evaluation factors and calculate their weights,with a risk assessment model for a singular ditch established.The results coincide with the field investigation. |
