A predictive framework for the flow control of environmental roughness

该项目旨在开发一个新的框架，以准确预测宏观粗糙度如何控制环境系统中的流动，湍流和传输。示例系统的范围从在水生环境中的海草草甸、珊瑚礁和可渗透床上的流动到在大气环境中的城市粗糙度上的流动。这些系统的整体健康和功能与它们如何改变营养物质、污染物、热量和生物群的流入和运输密切相关。预期成果包括新的理论和新的预测模型，以量化这些复杂的粗糙度系统的流量和运输的“气候”。这将改变我们对这些重要生态系统的理解、管理和保护的最佳实践。

This project aims to develop a new framework to accurately predict how macro-roughness controls flow, turbulence and transport in environmental systems. Exemplar systems range from flows over seagrass meadows, coral reefs and permeable beds in aquatic environments to flows over urban roughness in atmospheric environments. The overall health and function of these systems is intimately linked to how they modify the incoming flow and the transport of nutrients, contaminants, heat and biota. Expected outcomes include novel theory and new predictive models to quantify the flow and transport 'climate' in these complex roughness systems. This will transform best practice in our understanding, management and protection of these critical ecosystems.
