Description

In-situ investigation of dissolved oxygen fluxes in weir pools and rivers. This project aims to understand the turbulent mixing processes by which dissolved oxygen is transported from the surface of rivers and lakes into the water column by using unprecedented high-fidelity in-situ measurements. Australian inland rivers often go through prolonged periods of low flow and strong thermal stratification under which turbulent mixing is dramatically reduced resulting in low dissolved oxygen levels. These conditions can lead to large-scale fish kill events in fragile and endangered ecosystems. This study will develop gas transfer relationships that can be used in river hydraulic models by catchment managers to predict and manage the occurrence of high-risk conditions and enable proactive river management. .
