海底浊流是由于水中细小沉积物的稀释，使混合物的密度大于环境流体（海水）的密度而引起的。对海底浊流的调查很重要，因为它们可以通过沉积物的侵蚀和沉积来改变海底的水深。在这项工作中，我们提出了一个三维海底浊流的数学模型。该数学模型考虑了环境流体的卷吸、泥沙的沉降和沉积等主要问题。数值计算结果与实验结果进行了比较。一致性相当好，表明物理现象的主要特征是由
Submarine turbidity currents are caused by the dilution of fine sediments in water, making the density of the mixture greater than the density of the environment fluid (sea water). The investigation on submarine turbidity currents is important as they can modify the bathymetry of the sea bottom by means of erosion and deposition of sediments. In this work we propose a mathematical model for 3D submarine turbidity currents. Such a mathematical model accounts for the major issues: entrainment of environment fluid, sedimentation and deposition of sediments. Numerical results are compared with experiments. The agreement is fairly good and shows that the main features of the physical phenomenon are reproduced by the
