Dynamics of Suppressed Mixing Regimes in Australian Rivers

这项研究的目的是进一步的湍流混合在澳大利亚河流流动的背景下的基础科学。重点是在长期低流量条件下，再加上温暖的表面温度，导致水柱成为热分层，然后抑制湍流混合。河流系统的极端规模使得调查强分层混合制度的真实动态特别具有挑战性。通过采取世界上第一个现场测量湍流混合和进行高分辨率的数值模拟，这项研究将提供明确的数据，这将允许正确表征的混合制度，以及它们是如何与河流流量条件。

This study aims to further the fundamental science of turbulent mixing in the context of flow in Australian rivers. The focus is on prolonged low flow conditions which when coupled with warm surface temperatures cause the water column to become thermally stratified which then suppresses turbulent mixing. The extreme scale of the river systems has made investigating the true dynamics of the strongly stratified mixing regimes particularly challenging. By taking world first in-situ measurements of turbulent mixing and undertaking high resolution numerical simulations this study will provide definitive data which will allow correct characterization of the mixing regimes and how they are associated with river flow conditions.
