Abstract: During the dispatching of the Yellow River water quantity, especially in the non-flood season, water dispatching is very tense. ¡°Abnormal water loss¡± often occurs between the hydrological stations in the middle and lower reaches of the Yellow River. According to the hydrological data in the Loukou-Lijin section, water loss is calculated with the water quantity balance method. The sources of error and its influential degree are analyzed. And the countermeasures are presented to these sources of error.
