潮水河属河渠非恒定流。本文试图将水文测验与水力计算相结合,研究适合于潮水河计算的简化模型,提出由已知测站的水位、流量,逐时推算相邻站水位、流量的方法。此法曾应用于长江和珠江某感潮河段的计算,实例表明,提出的方法是有效而实用的。
The tidal river is a non-constant river. This paper attempts to combine hydrological tests with hydraulic calculations to study a simplified model suitable for calculating the tidal river. The method of estimating the water level and the flow rate of adjacent stations from the known stations’ water level and flow rate is proposed. This method has been applied to the calculation of a certain tidal reach in the Yangtze River and the Pearl River. The examples show that the proposed method is effective and practical.
