Abstract

The channel leakage loss of piedmont plain in north China directly affects the flood evolution law and ecological water diversion, especially in Haihe River Basin. The essay selected three typical river reaches of the basin to analyze the leakage loss of the historical flood processes using statistical method, studying the correlation between the leakage rate per unit river length and the upstream inflow, and the duration of flood under different water storage conditions. Meanwhile, the initial leakage loss rate of flood with different magnitude in each typical reach was estimated. The study results indicated: (1)The upstream inflow is negatively correlated with the leakage rate per unit river length; the leakage rate per unit river length tends to be stable when the upstream inflow increases to a certain value; (2)The duration of flood is negatively correlated with the leakage rate per unit river length when there is bottom water; (3)The degree of dryness in the early stage is one of the main factors affecting the seepage capacity; (4)The leakage rate per unit river length is generally logarithmic or exponential related to the upstream inflow; (5)In Haihe River Basin, the initial loss rate of medium and small water in typical reach is higher, more than 30%, and the initial loss rate of large water is lower than that of medium and small water.
