This article describes a mathematical model of suspended sediment transportation in a tidal river. In addition to the usual unsteady flow differential equations, the following conservative equation of sediment mass, based on the theory of diffusion, is introduced:in which A = cross - sectional area of channel, S = mean suspended sediment concentration in the cross - section ; Q = discharge; B= channel width; H = water depth; d= median size of sediment;ω= fall velocity, k = von Karman universal constant;u = mean...

This article describes a mathematical model of suspended sediment transportation in a tidal river. In addition to the usual unsteady flow differential equations, the following conservative equation of sediment mass, based on the theory of diffusion, is introduced:in which A = cross - sectional area of channel, S = mean suspended sediment concentration in the cross - section ; Q = discharge; B= channel width; H = water depth; d= median size of sediment;ω= fall velocity, k = von Karman universal constant;u = mean velocity in the cross-section) C = Chezy coefficient;ξ = constant, for Qiantang River equals 1/3; ψ = capacity load of the tidal flow. These equations deal with water and sediment separately. In the case of low concentration, it can be served as an approximation.The medium diameter d50 of the sediment, in which about 15% by weight is less than 0.02mm, is 0.02-0. 06mm. According to the analyses made with the vertical concentration profile of suspended sediment measured in fields, laboratory tests as well as the results from the verification of this mathematical model, certain rate of flocculation ard agglomeration of suspended sediment is expected under some conditions. In the case of △H/H中<1, thefollowing criteria are used:ω = 0.00114S0.366m/s, when ω>0.0015m/s;and ω = 0.0015m/s, when ω≤0.0015m/s;where △H = tidal range; H中= water depth below mean tidal level. The formerly deduced formula of suspended sediment transportation formean flood flow or ebb flow during a tidal cycle in the river, is used in this model for computing the instantaneous concentration, where k = 5-7 for straight reaches, but it increases greatly at river bends.The differential equations describing both the tidal flows and suspended sediment transport were solved using characteristic difference scheme with different length step △x. It is stable and convenient for computation.The verification computation was carried out in the Qiantang River from Tantou to Qibao and in its tributary Cao'e River from Sangpendian to Dingjiaba for forty three tidal cycles. The duration curve of the calculated suspended sediment concentration agrees fairly with the measured value on the whole as shown in Figs. 3,4 and 6.

本文采用小含沙量近似,初步建立了适用于钱塘江的潮流榆沙数学模型。验证计算和室内试验表明,中径为0.02～0.06毫米的钱塘江悬沙在沉降过程中会发生某种程度的絮凝。除涌潮掺混特別强烈的情况外,必须考虑加大沉速才能使计算的含沙量过程线符合实测资料(沉速变幅约一倍);还认为应考虑河湾对河流输沙能力的影响。在此基础上,对钱塘江、曹娥江部分河段共43个潮作了全潮含沙量过程验证计算,其结果与实测值比较接近。计算中使用了不等步长的特征线偏心差分格式。
