Factors affecting River Regimes

• amount, pattern, intensity


  regimes reflect seasonal rainfall patterns and snow and glacier melt patterns
• temperature 


  Influences evaporation rates, meaning less discharge
• Geology and Overlying Soils

  Water is stored in the grounds based on the permeability and porosity, and is gradually released into rivers
• Amount and Type of Vegetation

  Wetlands hold water and release it, lots of vegetation means more interception
• Human activities 


  Impermeable surfaces lead to run off, and dam building regulates water flow
