This research program combines the theoretical and experimental research of mechanisms of flow and sediment transport involved in the deformation of bed and banks of alluvial streams with the development of physically-based, high-accuracy numerical models for the simulation and prediction of river morphological changes. These changes may occur naturally or as a response to direct or indirect human river interventions. The proposed research focuses on: 1- large-scale turbulence coherent structures and their morphological consequences; and 2- bed morphological changes and bank migration in meandering streams.

该研究计划结合了与冲积流的床和冲积流的变形的流量和沉积物运输机制的理论和实验研究，以及开发基于物理的高能数值模型，以模拟和预测河流形态变化。这些变化可能自然发生，也可能是对直接或间接人类河流干预的反应。拟议的研究重点是：1-大规模的湍流相干结构及其形态学后果；和2床的形态变化和曲折流中的银行迁移。
