Then, transmission relationship between frequency for maximum flood discharge in a yearand frequency for every flood in this year was established. And based on the risk rate ofdynamic controlling reservoir water level in flood season defined by Prof. B.D Wang andmaximum entropy model of forecast error distribution, the definition of risk rates when usingflood forecast or combination of flood forecast and precipitation forecast to control limitwater level in flood season were difined. And their corresponded calculation methods weregiven as well in this dissertation.
