Research Abstract |
Morphology of bedrock rivers is often affected by various environmental factors including geologic, tectonic and climatic conditions. In this study the relationships between climate changes and bedrock river erosion, particularly focusing on the longitudinal profiles and knickzones, are examined by means of quantitative morphological and geospatial analyses. The results suggest that knickzones and related bedrock river morphological features are often affected by spatiotemporal changes in hydraulic forces and climate changes.
