Factors responsible for Fluvial processes and landforms

Channel Factors - (control the energy and flow of the river)

  • Channel shape - a smaller wetter perimeter per cross-sectional area is more effecient (hydraulic radius)
  • Channel size - larger channels are more efficient
  • Roughness - the rougher the bed the lower the energy
  • Gradient - a flatter gradient creates lower energy
  • Load - a heavy load means little spare energy
  • Base level - rising base level (usually the sea) means less energy
  • Type of flow - turbulent flow uses energy
  • Hydrography - flashy hydrographs (sudden rise in flow) mean more energy
