Abstract: This paper applies the sediment numerical model to forecast the useful life for flow path of Qingshui Gully. Calculation results are analyzed by combining those of the mathematic model applied by China Institute of Water Resources and Hydropower Research, and analyzed by applying the storage volume approximation method. We draw the conclusion that the flow path for Qingshui Gully of Yellow River Estuary can maintain its performance for about 50 years.

Key Words: Yellow River (YR); flow path of Qingshui Gully; useful life for flow path; scheme.
