Research Abstract

The information on the flow and the substrate is important andnecessary for the habitat assessment of aquatic species as well as the management and restoration of the riverine ecosystem. In this research, the flow field, bed morphological change and the sediment size distribution around a typical river restoration structure, spur dyke, are investigated with laboratory experiment, field survey and numerical simulation methods. Based on the research results, environmental restoration schemes are proposed with scientific evidences and advanced numerical analysis and assessment tools are developed
