    This study aims to evaluate the effective for the alternative water in a disaster and the characteristics of hydrologic science for 3 spring waters and 1 spring waters as reference in Oita. The study term was 2013 to 2017 including Kumamoto earthquake and Aso eruption in 2016. According to the tri-liner diagram and hexane diagram, the dissolved component had shown annual flections. There samples were met the standard in the water experimental index of emergency for an earthquake of disaster. Therefore it could not confirm the impact of earthquake disaster. pH and NO3-N in Aso eruption shown the impact. There were possible that a required amount of discharge covered for a few hours in an emergency of earthquake disaster. Therefore the 3 spring waters are useful for alternative water when a disaster occurs.
