Outline of Final Research Achievements

It is very important problem to understand the budget of water and mass in a watershed for management of water resources and sustainable water use. Though measurement or estimation of the total effluent load of water quality are necessary for the understanding of mass balance in a watershed, they are not so easy works. It requires great cost and labor with a traditional method in which a lot of water samples should be collected and the concentration of quality should be analyzed. Sometimes, a regressive relation between the load and discharge of flow is alternatively used, but it may be not accurate. In this study, a new system to measure the load of water quality was developed and applied into the experimental forest watershed. Then the availability of the system was inspected and the water and mass balance were discussed in the watershed.
