| Outline of Final Research Achievements |
Through the forest management such as thinning, effects of the coverage by litter on the forest floor to the water movement and sediment discharge process were investigated in mountainous slope covered by coniferous forest in Japan. Observed rainfall and surface runoff events showed quick discharge process on the forest floor surface layer. And relation of seasonal change of organic matter content and litter on the forest floor were measured. Those materials are able to become effective prevention of soil and sediment discharge. To consider sediment discharge from mountainous stream, the treatment of litter coverage must by a important factor.
