| Research Abstract |
Forests are mentioned as "green dams". Some people speculate that forest management can be alternative for dam reservoirs from the viewpoint of securing water resources. We examined validity of this speculation. Increase in low flow due to forest management was higher than that due to dam reservoirs for six of 45 dam reservoir watersheds in Japan. Increase in low flow due to forest management was lower than that due to dam reservoirs for the remaining 39 dam reservoir watersheds. Thus, the speculation was invalid for most cases in Japan.
