The relative efficacy of fluvial and glacial erosion over modern to orogenic timescales

  title={The relative efficacy of fluvial and glacial erosion over modern to orogenic timescales},
  author={Michele N. Koppes and David R. Montgomery},
Since the late nineteenth century, it has been debated whether rivers or glaciers are more effective agents of erosion1. The dramatic landscapes associated with glaciated terrain have often led to the argument that glaciers are more erosive than rivers, and recent studies have documented the topographic signature of an ice-controlled limit of mountain height known as the ‘glacial buzz-saw’2,3. Here we present a new global compilation of erosion rates, which questions the conventional view of… CONTINUE READING
