| 1 | A new algorithm for bank-failure mechanisms in 2D morphodynamic models with unstructured grids显示文摘河岸失败是在似地球形状的过程的重要现象。面对河岸或陡峭的 bedforms,水级的上升深深地导致的倒塌机制与沉积运输过程一起影响床进化。在这份报纸,能够在一个二维的二阶段的 morphodynamic 模型模仿如此的机制的一个算法被介绍。混合的 A 以房间为中心、以节点为中心的有限卷的 discretization,使用一个未组织的三角形的网孔并且在只有一个意义地要定义的每个房间允许斜坡,被建议。geo 失败操作员保证当在房间床斜坡超过一个批评角度时,相应的床材料和毛孔水将成为床运输的部分并且然后将跟随二阶段的流动的动态方程。算法有效性被一些试验性的测试的数字繁殖从文学显示出。 | Stefania Evangelista Massimo Greco Michele Iervolino Angelo Leopardi Andrea Vacca | 2015 | International Journal of Sediment Research2015，30，4： | 4 |
| 2 | Simulation of dam-break waves on movable beds using a multi-stage centered scheme显示文摘This paper presents the application of the multi-stage first-order centered scheme GMUSTA to solve a two-phase flow model with four equations for simulating dam-break floods without and with sediment transport.Computation of generalized Riemann invariants can be particularly complex and costly in simulating dam-break floods with sediment transport.GMUSTA numerical scheme,which does not require complete knowledge of the eigenstructure of the hyperbolic mathematical model,offers a suitable and attractive option.The quality of the dam-break flood simulations with GMUSTA scheme is verified by comparing the results against laboratory tests and some experimental data available in the literature,on fixed and mobile bed conditions,with different bed materials and flush or stepped bottoms.The numerical results reproduce quite well the experimental evidence,proving that the model is capable of predicting the temporal evolution of the free-surface and the bed.The GMUSTA scheme,which is not only simple to implement but also both accurate and computationally efficient,is proposed as an appropriate tool for integrating non-equilibrium sediment-transport models. | Stefania EVANGELISTA Mustafa S.ALTINAKAR Cristiana DI CRISTO Angelo LEOPARDI | 2013 | International Journal of Sediment Research2013，28，3： | 2 |
| 3 | A two-phase model for fast geomorphic shallow flows显示文摘纸介绍 2D 浅水模型基于为快似地球形状的 transients 的分析的二阶段的明确的表达发生在河 morphodynamics 的上下文。质量和动量保存原则独立为两个阶段被强加。模型自然地说明非平衡固体运输,自从两个即时改编假设也不任何东西落后方程被采用代表沉积动力学。建议模型的夸张特性被显示在流动条件上独立地被保存。从 1D 和 2D 测试用例的数字模拟的结果与文学相比试验性的数据并且与可得到的数字解决方案。 | Massimo GRECO Michele IERVOLINO Angelo LEOPARDI Andrea VACCA | 2012 | International Journal of Sediment Research2012，27，4： | 0 |
