主讲内容介绍：Infragravity (IG) waves are ocean surface waves of low frequencies, typically between 0.004 and 0.04 Hz, that distinct from the wind waves or swells of frequencies between 0.04 and 1 Hz. IG wave plays an important role in many coastal processes, such as resonance in harbours, morphological evolution, and hydrodynamics in surf zones of beaches and on coral-reef flats. Under certain conditions, IG waves may account for 50% of the bottom shear stress and 41% of the runup. In this talk Dr. Zhiling Liao will provide an overview of the characteristics and modelling of IG waves in two coastal environments: beaches and coral-reef flats. He will discuss how our understanding of wave effects on ecosystems and the role of IG waves in hydrodynamics can inform us about the potential impacts of IG waves on coastal ecosystems. At the end of the talk, he will also present briefly the numerical modelling work of plastic transport in coastal area of Red River in north Vietnam dedicated to the NERC funded project ‘Sources, Sinks and Solutions for the Impact of Plastic on Coastal Communities in Viet Nam’.
