Abstract

The requirements on the models for computing volumes and areas of contaminated zones of water reservoirs by suspended materials and other admixtures imply that multiscale turbulence, suspension sedimentation, attachment conditions for suspended particles at the water–bottom boundary, jet effects, and salvo discharge of soil must be taken into account, which allows more accurately evaluating the spatial distribution of the concentrations of the pollutants and the dimensions of their impact zones. In this study an improved set of coupled transport models of suspended matter and sediment is described, which takes into account the dynamic variations in the calculation domain, the variation in the medium’s density due to suspensions, and their multicomponent character. A model for calculating the suspended matter in pollution zones in the presence of wave processes is developed in which the dynamic restructuring of the calculation domain appears not only due to the variation in the geometry of the level elevation function but also due to the variation in the bottom relief due to the suspension’s sedimentation.

考虑到海岸带三维水动力过程的悬浮物耦合运输模型集

摘要

计算悬浮物和其他掺混物对水库污染区的体积和面积的模型的要求意味着，多尺度湍流，悬浮物沉降，水底边界处悬浮颗粒的附着条件，射流效应和土壤的齐放排放必须考虑到这一点，这可以更准确地评估污染物浓度的空间分布及其影响区的大小。在这项研究中，描述了一套改进的悬浮物和沉积物耦合传输模型，其中考虑了计算域中的动态变化，由于悬浮物引起的介质密度变化及其多组分特征。
