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.

森林被称为“绿色堤坝”。有些人推测，从确保水资源的角度来看，森林管理可以替代水坝水库。我们检验了这种推测的正确性。在日本45个水坝水库流域中，有6个流域由于森林管理而增加的低流量高于水坝水库。在其余39个大坝水库流域，森林管理导致的低流量增加低于大坝水库。因此，在日本的大多数情况下，这种推测是无效的。

项目成果

Evaluating the contribution of dam reservoirs located upstream of the Tokyo metropolitan area during low flow periods.
