一个详细的数学模型的疏浚渠道，沉积的基础上，所有相关的运输过程，如对流，混合和沉淀的详细表示。这是一个重要的优势相比，传统的预测公式，这是基于一个相当强大的模式化的传输过程。敏感性分析显示的流线折射效应和波浪浅滩效应在渠道上的沉积过程的影响。提出的数学模型的两个应用程序给出，并显示合理的测量和计算的浓度和沉降速率之间的协议。最后，给出了一组图表，可用于粗略估计疏浚渠道的截留效率。
A detailed mathematical model for sedimentation of dredged channels, based on a detailed representation of all relevant transport processes such as convection, mixing and settling, is presented. This is an important advantage compared with the traditional prediction formulas, which are based on a rather strong schematization of the transport processes. A sensitivity analysis is presented showing the influence of the streamline refraction effect and the wave shoaling effect in the channel on the sedimentation process. Two applications of the proposed mathematical model are given and show reasonable agreement between measured and computed concentrations and sedimentation rates. Finally, a set of graphs is presented which can be used to get a rough estimate of the trapping efficiency of dredged channels.
