A PROPOSED METHOD FOR QUANTITATIVELY EVALUATING SEDIMENT DISASTER COUNTERMEASURES

Abstract

 To develop countermeasures for sediment disasters such as slope collapse, it is necessary to perform comprehensive analyses of their practicality, environmental effects, and costs to determine an optimal trade-off of these factors and ensure accountability. In this study, we quantitatively evaluated trade-offs among these factors using a questionnaire survey and analytic hierarchy process methods to model the decision-making procedures of engineers and other contributors in designing sediment disaster counter-measures. We also propose a case study for this evaluation method.
