<br />frequency relation of peak flow or stage to yield an exceedence fr~quency <br />of damages relationship. This latter relationship is subsequently integrated to <br />yield the expected value of annual damages. The simulation program accepts <br />damage functions in the form of flow damage or stage damage relations. accepts <br />exceedence frequency functions in the form of flow or stage cxccedencc <br />frequency, and develops from hydrologic input a range of hydrologic runoff <br />events for the watershed that are used to develop modified conditions ,(with <br /> <br />,~F/ <br /> <br /> <br />Do_~-$ Dischgtlll Dischargl <br /> <br />o A"''''''--' <br />, / <br />. / <br />t "'...., <br />~ Modified <br />c: (Se. bfiow) <br /> <br />Eli.tinllElpected <br />.
