| Research Abstract |
To elucidate the source area of leaf-litter to streams, travel distance of willow leaves were investigated at two riparian forest. Leaf dispersal areas of the litterfall were to 15 . 25m from the tree root, depended on the wind direction. Few leaves moved on the forest floor during the winter. A new dispersal model I developed was able to estimate the leaf dispersal patterns accurately. We are sure that this model is useful to reveal source area at any riparian forest.
