Repeated measurements

(2 weekly/ monthly):

  • Soil moisture with soil samples. Frequency two weeks (if possible more frequently) and after rainfall.
  • Soil organic matter (in laboratory by ignition loss).
  • Soil strength of moist soil (shear vane, in kPa)(we need these tools).
  • Surface roughness (max difference microrelief in cm).
  • Steady state infiltration rate, using double ring infiltrometer (mm/h).
  • Empty sediment tanks and estimate volume at regular intervals, if possible after each rainfall. Checked every week for activity. Volume is estimated and 5 samples of 100CC are taken for dry weight analysis, each time the sediment tank is emptied.
