Recently, it has become evident that the water management system for rational distribution of irrigated water should be clarified, and facilities for water management should be introduced and arranged more pertinently.<BR>The forms of water demand and their properties in farming land are important factors for solving the problems aforementioned, these are understood qualitatively, but their actual conditions are not clear.<BR>Accordingly, in this study the actual conditions of the utilizing forms of intake-water in the mixed areas of a paddy and a dry field are clarified and their characteristic, and countermeasures are discussed.<BR>A more remarkable characteristic is that intake-water can be easily directed into a paddy field.<BR>The basic reason seems to arise from the following fact;excess water in a paddy field does not involve actual damage, and additional water in a paddy field makes easier distribution of irrigated water by other water management;on the contrary, excess water in a dry field brings about wet damage and then regulated without supervision and excess water-intake never occur.<BR>Therefore, in mixed areas of a paddy and a dry field, it is very important to introduce check system for preventing excess distribution of irrigated water into paddy field.
