    The recharge during a unit time step (T2−T1=1) can be found from R = Rain − Sd The actual storage at the end of a unit time step is found as Sa2 = Sa1 + Rain − R − Ea, where Sa1 is the actual storage at the start of the time step. The Curve Number method (CN method) gives another way to calculate the recharge.
