Introduction
IAHR President's Webinar is a serial of events that aims at inspiring, disseminating and catalysing knowledge and thinking on the most important water engineering and related environmental issues of present times through high-quality and tasteful online events.
The first of this series of webinars will be centered on the topic of lake environmental hydrodynamics, featuring Prof. Jorg Imberger, University College London, UK and University of Miami, USA as the keynote lecturere, as well as two invited speakers: Prof. Yong Liu from Peking University, China and Prof. Steve Monismith from Stanford University, USA, and will be co-chaired by IAHR President Prof. Joseph Lee and former IAHR Vice President Prof. Angelos Findikakis.
Prof. Jorg Imberger , after a review of the important physical processes and the non-dimensional numbers that govern each of hydrodynamic processes in a lake, will explain how the increasing stability of deep lakes is resulting in a delay in lake turnover and an ever-increasing volume of the zero oxygen hypolimnion that is killing the endemic biodiversity in deep lakes, as well as how the new adaptive, real-time, self-learning management approach may be used to avoid this disaster from happening. [Abstract of this talk]
Prof. Yong Liu will focus more on a case study, talking on the pollution of the Lake Dianchi, and the mitigation actions launched to restore one of the three most polluted large shallow lakes in China. Models will also be explained to analyze the temporal variations of 30-year water quality change and explore the joint effect of external nutrient input and internal cycling. [Abstract of this talk]
KEYWORDS:
Algal bloom; Hydrohynamics of lakes; surfaces fluxes and basin scale response; inflow/outflow dynamics; gravitational motions; benthic boundary layer dynamics; energy cascade; stratification control

Prof. Imberger's Related Talks
At this webinar, Prof. Jorg Imberger will be giving the 2nd talk of a series of three closely-related lectures:
Talk 1: Summary of the problems motivated by the idea but you cannot solve a problem until you see that you have a problem. [Given during the IAHR 85th Anniversary Summit on December 15, 2020] [More] [Video Playback]
Talk 2: Basically a technical tutorial for the practicing engineer how to implement the solutions for the problems. [To be given at this webinar]
Talk 3: This talk may be viewed as a user manual of how to use technology to solve the Lake problems and how to integrate this solution into the fabric of the stakeholder community. [To be given during the Fundamental Issues of Global Water Security: Linking Water Security to Nature on March 22, 2021] [More]
