Turbulence: Physical Modelling and Application to Aquatic Ecosystem Functions

Grant number: FL120100017 | Funding period: 2012 - 2017

Completed

Abstract

Turbulent fluid motions in aquatic systems are critical for many aspects of water health. This project will quantify the effects of these motions in an unprecedented way by addressing the long-standing problem of turbulence, and the outcomes will be applicable to the essential task of strengthening Australia’s water security.
