Abstract:
Turbulence generated by aquatic vegetation plays a vital role in the interfacial transfer process at the air-water interface and sediment-water interface (AWI and SWI), impacting the dissolved oxygen (DO) level, a key indicator of water quality for aquatic ecosystems. This research investigates how flow-vegetation interactions affect suspended sediment dynamics and the interfacial transfer process across sediment-water-air interfaces in unidirectional vegetated flows. A series of laboratory experiments in a unidirectional recirculating flume with simulated rigid vegetation and a sediment bed was conducted to investigate the influence of vegetation under different submergence ratios and plant densities. The experimental result shows how different scales of vegetation-generated turbulence affect the interfacial gas transfer rate at different submergence ratios and array densities. This study is expected to provide critical insight for future studies on water quality management and ecosystem restoration in natural vegetated water environments such as lakes, rivers, and wetlands.
