Description of the test aquifer
view of testaquifer
view of testaquifer
  • l x h x w : 3.54m x 0.54m x 0.17m
  • quartz sand 1 (Ø 0.3-0.8mm), quartz sand 2 (Ø 0.1-0.4mm)
  • kf1= 1.4·10-4 m/s ; kf2= 6.0·10-5 m/s
  • ne1 = ne2 = 38.5%

Boundary conditions
  • top and bottom of the test aquifer impermeable, except the infiltration point of the high concentrated Salt water
  • gradient between left and right boarder: 4cm
  • infiltration rate of salt water: Q = 1.89·10-6 m³/s
  • duration of salt water infiltration: 90 minutes
  • salt water concentration: 140 g/l natriumchlorid
