In Nigorikawa and Otakigawa, EC was gradually lowered pH in the end of January and up to stable. The influence of snowmelt also fell also pH EC reached a peak at the end of April began to appear from February. It was lowered pH again EC is increased because of the rainy season in June. Summer, but volcanic ash that was deposited under the influence of the typhoon had a major impact flowing out, the end of October was stable.
