Research Abstract

As the research fields of representative rural regions in Japan, five areas were selected. Those are low-lying paddy district in Niigata, large scaled polder in Akita, creek basin in Kyushu, organic farming field in San-in and forest-cleared basin in Hokkaido.
The changes of land use and farm management are supposed to affect water circulation and water environment in surroundings. Therefore, water budget and water quality in the research fields were measured periodically both in irrigation seasons and in non-irrigation seasons.
Main results of analyses are as follows :
1. The amount of water storage and the velocity of water circulation in the region were clarified to have a strong influence on water environment, especially in a low-lying district.
2. The complex tank model of water circulation in the basin could be constructed, based on the water budget system. Since this model can simulate water management and water quality, many kinds of information about the effects of land use or water reuse were obtained.
3. The result of multiple regression analysis showed that the reclamation of forest brings about steep runoff and material load, so that land use and water management should have a direct relationship.
In this way, the water management system for the conservation of water environment was indicated by means of several kinds of quantitative analyses.
