摘要

In the Hiji River, flood water level records for 320 years have been collected. These long term records are rare and valuable in Japan. By analyzing these records, we calculated the probabilities of floods in each period and studied the safety levels of flood control by examing the changes in improvements of embankment dam construction and other flood control measures. The main findings of this research are as follows: 1) Flood water level records show that the safety levels of flood control has been improvedalong with flood control measures. 2) The safety level data based on flood water levels almost agree with those based on rainfall.
