Repeated measurements
(2 weekly/ monthly):
- Soil moisture with portable TDR probe (0-10 cm depth), 10-12h morning, average of 5 measurements per sample location. Frequency weekly (if possible more frequently) and after rainfall
- Soil organic matter (in laboratory by ignition loss)
- Soil strength of moist soil (shear vane, in kPa)
- 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
