海洋科学学术讲座预告第381期：关于河口动力机制的半解析模拟研究

报告内容简介：

        Climate change and coastal development have resulted in increasing estuarine and coastal risks such as flooding, turbidity, erosion/deposition, salt intrusion. However, our ability to understand and predict the variability and impacts of such risks, which is essential for managing the adverse impacts of climate change and human activities on the sustainable functioning of these systems, remains limited. The main reason for this is associated with the complex spatio-temporal variability of water levels, currents, salinity, and sediment concentrations, which are controlled by various poorly understood processes and their potential interactions. In this presentation, Xiaoyan is going to introduce a few process-based, idealized semi-analytical models that allow us to explicitly dissect the contributions of different physical processes to marine hydrodynamics and material transport. She will show a few examples where these models were successfully used to systematically investigate the controlling physical processes of extreme water levels, tidal currents, residual circulation, sediment and salt transport, and their sensitivities to natural and anthropogenic changes.
