| Abstract: | In this paper, the present situation, the cause and the harm of the absence of flow in the Huanghe River were briefly introduced. The changing regularities of the absence of flow, which include the law of double peaks in a year, the multi year relationship between the demand and supply of water, the relationship between the days of the absence of flow in Lijin Station and the monthly discharges in Huayuankou Station, the relationship between the number of the whole day absence of flow and the number of the absence of flow in a day or in several hours, were preliminarily revealed. The development tendencies of the absence of flow, that consist of the longest period or accumulative days, the longth and the beginning day of the absence of flow in Lijin Station, were statistically analyzed. The research results provide the scientific basis for the forecast of the absence of flow in the Huanghe River, which are useful to the departments concerned. |
