- - - - Temperature
      - Vegetation
      - Wind
      - Soil moisture content
- - - - Size of Basin
        
        Smaller basin greater discharge as shorter distance for water to go
      - Shape of Basin
        
        circular basin shorter lag time
      - Basin relief (slope)
        
        steep slope water flows more rapidly
      - Soil Type
        
        clay soils and thin soils saturate quickly more surface runoff faster hydrographic compared to sandy thick soils.
      - Rock Type
        
        impermeabel rocks increase surface runoff reduce lag time
      - Drainage Density
        
        high number of tributaries greater channel flow, shorter lag time
      - Vegetation cover
        
        increased vegetation cover leads to more interception and EVT
      - Land Use
        
        urban surfaces have more imperil surfaces faster and more direct to the river
      - Precipitation intensity
        
        high intensity fills infiltration capacity and therefore increases surface runoff
      - Snowmelt time
        
        faster melting shorter laf time
      - EVT
        
        High EVT will reduce discharge and subdue the hydrograph
