摘要
受洪水涨落和回水顶托影响的水位流量关系一般为复杂的时序型绳套曲线 ,通常可用落差指数法作单值化处理 ,但由于落差指数法需经反复试算 ,给电算带来不便 本文提出了落差指数直接解算的数学模型 。
In general,stage discharge relationship influenced by fluctuation rate of flood and setup of backwater is time sequence loop curve in natural river,and the fall exponent method is used to single valued processing.But fall exponent method exists some inconvenient in the data processing by computer,because this method needs cut and try again and again.This paper puts forward the direct calculation mathematical model of fall exponent for using computer.Finally,this model is applied for stage discharge relationship analysis in Luoshan Station at middle reaches of the Yangtze River.
