The study looked at how rainfall affects soil erosion on slopes. They used simulated rainfall to see how quickly runoff occurred and how much sediment was produced. They found that higher rainfall intensity and steeper slopes led to faster runoff. The amount of sediment produced increased with rainfall duration but then decreased. The relationship between sediment yield and runoff followed a predictable pattern. The size of sediment particles changed depending on the intensity of rainfall, with smaller particles becoming more common at lower intensities.
