Uniformization scheme of water level and discharge of Hankou Hydrological Station and its application
摘要
Abstract
The relationship of water level and discharge of Hankou Hydrological Station on Yangtze River is influenced by flood and backwater fluctuation and erosion-deposition variation, so it presents an irregular loop curve. The comprehensive fall expo-nent method was adopted to uniform the relationship of water level and discharge. According to the hydrological characteristics of river reaches at upstream and downstream of Hankou Hydrological Station, the existing gauge of water level stations in the meas-ured reach were adopted as the auxiliary gauge of Hankou Hydrological Station. By using the measured data from 2003 to 2008, the uniformization scheme of water level and discharge is studied. The results showed that the difference of the results calculated by comprehensive fall exponent method and TSLC method were small. Therefore, the uniformization scheme can be used in dis-charge data processing and flood forecast, and its application can reduce discharge measurement numbers and improve working ef-ficiency.关键词
