 ====Adjusted Curve Number====
-Peak rate and volume calculations should follow the steps below to determine an adjusted curve number for use in hydrology calculations. Volume reduction on a green roof is achieved primarily through the drainage layer and growing medium components, which absorb and retain a portion of the rainfall that lands on it making it available for plant uptake and evapotranspiration. For the calculation of runoff retention in the growing medium, the maximum available water capacity for runoff reduction is the difference in the water content between the field capacity and the wilting point.
