DYNAMICAL MECHANISM,PHYSICAL EROSION PROCESSES AND INFLUENCE FACTORS OF FLUVIAL INCISION: A REVIEW AND PROSPECT
|
Abstract:
The term “fluvial incision" refers to vertical incision of stream channel into bedrock. Since 1990's, because of recent recognition of potential global-scale interactions among climate, surface processes, tectonics, needs of engineering constructions and critical land-use decisions the theoretical problems of bedrock channel fluvial incision have been brought to the forefront of tectonic geomorphology. This paper provides a review of the recent development of the research on fluvial incision from dynamical mechanism, physical erosion processes, influence of external variables, dealing with tectonics, climate and base-level change, and possibility of distinguishing their influences. The research of fluvial incision in the future will explore more scientific problems concerning both fluvial dynamics and geodynamics.
