| Tadashi Suetsugi presented material describing how, in Japan, vegetation encroachment has been occurring in many rivers. NILIM is studying on a restoration method of the fluvial system by widening the river channel and supplying gravels at upper reaches focusing on the Nagata district of the Tama River. And it is verified that this restoration technique has been effective through the observation in 2001-2002. USGS started the restoration by vegetation clearing in the Platte River in 2002. Both Institutes will continue the collaboration on these issues. |
