DYNAMICS AND MODELLING OF LARGE-SCALE RIVER ADJUSTMENTS OF EQUILIBRIUM

这项研究计划将冲积河流河床和河岸变形所涉及的水沙运动机理的理论和试验研究与开发基于物理的高精度数值模型相结合，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，也可能是对人类河流直接或间接干预的反应。拟开展的研究主要集中在：1-大尺度湍流相干结构及其形态后果；以及曲折河流中的两床形态变化和岸滩迁移。

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.
