    Cards (21)

    • What type of rainfall happens in the upland area
      Orographic
      Frontal - due to Western location
    • What is the annual percipitaion of the upland area

      1200mm/year
    • Why is their high amounts of run off in the upland area

      steep sided V shape valleys
    • Why is their limited soil stores in the upland area

      Thin soil and bare rock
    • Why are their low infiltration rates in the upland area

      low permability peaty soil
    • What are the infiltration rates in the upland area
      1mm/hour in winter
      5mm/hour in summer
    • What are the manmade stores of water in the upland area

      Cow Green
      Selet reservior
    • How much water do the upland manmade water stores hold

      40 million cubic meters
    • How does limited human development benefit the water cyclein upland areas
      allows interception
      infiltaration
      throughflow
    • How has hill sheep farming effect the water stores in upland areas
      extensive deforestaion
      reduced interception
    • Where does the lower course lie 

      the rain shadow of the Pennies
    • How much percipitaion does the lower course recieve

      650mm/year
    • How does the low lying flat floodplain effect the infiltraion of the lower course
      encourages infiltration
    • Why is their high infiltraion in the lower course
      Moderately permable clay and rich soil
    • How much percipition does the lower course get

      rural areas - 20mm/hour in summer
      4mm/hour in winter
      4 times faster than the upper course
    • What is the Teeside population
      300,000
    • What is the Darlington population

      100,000
    • What is their more of in the lower course and how does it effect transfers

      more impermable surfaces and drainage channels meaning surface run off to rivers (Skerne) happens quicker
    • Why does the lower course have flatter , fertile land
      intensification of farming - arable crop farming
    • Why does soil compaction happen in the lower course and how does it effect the water cycle
      use of machinery leads to soil compaction making the soil less permable leading to more surface run off and stores
    • How does the intesification of farming and urbanisation lead to
      extensive deforestion which leads to less interception
