Abstract
In order to compare multi-functional roles of irrigation water in Kanazawa and Shichika, the features of those irrigation waters were investigated. The results obtained are as follows:(1) Using the results obtained by the matching coefficient method from questionnaire section (1) “the purposes of present water use” and section (2) “multi-functional roles of irrigation water”, each item was classified into three categories labeled living, life-friendly and environmental water. The first category is small in Kanazawa but abundant in the Shichika District.(2) Using questionnaire above mentioned section (1), (2) and (3) “desired improvement point of irrigation water”, the relations among each item of the questionnaire shows a close relation, which means that some people evaluate the multi-functional roles of the questionnaire section item, while other people also evaluate the same item statistically with the same probability. Applying this results, a very fine relation was found between the probable expected value and the order of the mean value. The deviation of each item from the mean values was quite different between Kanazawa water and Shichika district water. The deviation was much greater in Kanazawa than in the Shichika District.
