【Abstract】 Definition method of design flood water level for tidal reach mainly included in direct frequency analysis method for flood water level, indirect method getting design flood water level from design rainstorm, and frequency combination method. The water level function, which described flood water level relation to watershed average precipitation and tidal level, was established. Based on the concept of flood water level function, design flood water level was obtained with frequency combination method. The practical application result indicates that the method put forward in the paper is simpler and valid, and the flood water level obtained is reasonable.更多还原
