Infiltration capacity curve:. A graph showing the time-variation of infiltration capacity if the supply were continually in excess of infiltration capacity. . Learning objective. Be able to calculate infiltration, infiltration capacity and runoff rates using the methods described in the Rainfall Runoff workbook chapter 5 and . Dingman. . chapter 6.. Problem 1 as an example. (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..

We encourage you to ask questions during the webinar so that we can clarify issues as we go through the material. Water entering the soil at the ground surface . It replenishes the soil moisture deficiency and the excess moves downward by force of gravity called deep seepage or percolation and builds up the ground water table .
