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.

该研究项目将冲积河流河床和河岸变形所涉及的水流和泥沙输运机制的理论和实验研究与基于物理的高精度数值模型的开发相结合，用于模拟和预测河流形态变化。这些变化可能是自然发生的，也可能是对人类直接或间接干预河流的反应。建议的研究重点：1-大规模湍流相干结构及其形态后果;和2床形态变化和银行在曲流迁移。
