COMPARISON OF NATURE-ORIENTED RIVER REVETMENT AND NATURAL RIVER BANKS IN THE MOUNTAIN STREAMS
Hiroyuki SUZUKI, Keigo NAKAMURA, Yoshiyuki MAEDA, Takashi KAI and Atsushi HATTORI
Improving stream restoration technique on post-disaster river works and planning in the mountain area, engineered river banks with revetments (e.g. concrete, rock) were compared with nearby natural ones.
The data on river landscape, vegetation and physical condition were collected at 32 sites, respectively.
From landscape viewpoints, plants above revetment, and plants and gravel sedimentation covering the foot of revetment played an important role to harmonize with surrounding natural landscapes. Plant spe- cies on revetment were characterized with fewer species that thrive in the shade because they were affect- ed by the increment of sunlight intensity. The plants covering revetment were similar to that revetment above. This indicates that vegetation above revetment supplies seeds on revetment and influences the spe- cies composition on it.
