The steeper the slope the higher the water erosion because steeper slopes increase the flow rate of water runoff by gravity.

The fewer or lack of vegetation on the slope increased the rate of water erosion. This is because vegetation reduces the flow rate of water runoffs hence reducing the capacity with which they can carry more sediments.

The higher the rain intensity the higher the rate of water erosion. This is because higher intensity increases splash erosion - during the impact of water drop on the surface when the fall from the sky - and also increases water surface runoffs because the rate at which the water runs of the surface exceed the rate at which the water infiltrates into the ground.
