Introduction
Test Setup:
The rainfall simulator
The soil tank (empty)
The soil tank (filled with silt)
Methodology and Observations:
Rain starts (time = 0)
Soil surface after 5 min (time = 5 min)
Soil surface after 40 min (time = 40 min)
Measuring rainfall intensity
Soil surface after 90 min (time = 90 min)
Collecting runoff (from time = 133 min to time = 151 min)
Measuring total mass (water + sediments + beaker's weight)
Drying the sediments in a soil drying oven
Soil surface after 170 min (time = 170 min)
Measuring total mass of sediments (sediments + beaker's weight)
Results
Water flow over time
Runoff coefficient
Sediments flow over time (g/min)
