Distinguish between solutions based on their degree of saturation: saturated, supersaturated, and unsaturated solutions.. (Mays p 310-321). Learning objective. Be able to calculate infiltration, cumulative infiltration and time to ponding using the Green-. Ampt. method as given in Mays Section . 7.4. The rate at which water can infiltrate is important for determining the partition between whether rainfall infiltrates or becomes runoff that flows overland to streams..

Historically the distinction between inorganic and organic substances was based on whether or not they were produced by living systems.
