The higher the amount of rainfall the more the surface runoff water facilitating increased rainfall and viceversa.

The more hilly or slopy lands have high gradient thus the steep graduent facilitates increased surface runoff water as compared to fairly flat lands that are less prone to surface runoff which only occurs at a decreased rate.
