Outline of Final Research Achievements

The authors has developed the reliability analysis method considering some kinds of natural hazard to evaluate the safety of river dike properly in Japan. The basic theory has been presented based on investigation that the researches in the Netherland where reliability analysis method has been progressed for river dike.Furthermore, the idea implemented to the data of an actual 35km stretch of a fairly large river running through one of the major cities in Japan.
