In this investigation the amount of rainfall proved to be positively correlated to the relative amounts of the sand fraction and negatively correlated to the clay fraction being entrained and transported by surface wash. Rainfall intensity showed the opposite trend, negative correlation to the sand fraction and positive correlation to the clay fraction.
