Periods of high temperature heat the surfaces of the oceans and lowland rivers, thereby increasing stratification and inhibiting mixing. This undermines the processes that normally distribute heat and CO2 and can lead to processes like rapid destratification in rivers that can result in mass fish-kills. This project aims to reveal the mixing and destratification mechanisms driven by turbulence from wind and sudden temperature change in oceanic and riverine systems through controlled laboratory experiments, targeted field measurements and theoretical modelling. Outcomes will include physical understanding, predictive models, and practical tools for waterway management, with the potential for better management of our riverine systems.

高温时期的海洋和低地河流的表面，从而增加了分层和抑制混合。这破坏了正常分布热量和二氧化碳的过程，并可能导致河流快速破坏的过程，从而导致大规模鱼类杀伤。该项目旨在通过受控实验室实验，针对性的现场测量和理论建模来揭示由风和河流系统突然温度变化驱动的混合和破坏机制。结果将包括物理理解，预测模型和用于水道管理的实用工具，并有可能更好地管理我们的河流系统。
