A synthetic rainfall curve is a plot of rainfall depth versus time that can be used in lieu of actual rainfall event data. A synthetic rainfall distribution is useful because it incorporates maximum rainfall intensities for a given event frequency arranged in a sequence that produces peak runoff. Therefore, a single rainfall distribution can be used to determine peak runoff rates for watersheds of various sizes and times of concentration.
