中文摘要
河流和小溪是全球生态系统的重要组成部分。人类的改造和污染已使它们中的许多不再能够提供充分的生态服务和功能。近年来,在恢复河流和溪流方面投入了大量努力,以改善它们的健康、促进生物多样性和增强复原力。在许多恢复解决方案中,模仿自然运作的方法越来越多地被采用,例如,将木材重新引入河流和溪流。然而,通过提高对修复结构周围物理过程的科学理解,可以增强这些基于自然的解决方案的知识库。本研究的主要目的是提高基于自然的河流和蒸汽恢复方法的知识库。在这项工作中使用的研究方法利用了最先进的计算技术,使得解决复杂的几何修复结构成为可能。预计该项目将揭示修复结构周围和内部的物理过程。对物理过程的理解对于成功实施基于自然的解决方案至关重要。具有生态功能的河流和溪流为周围的社区增添了巨大的社会经济价值。该奖项反映了美国国家科学基金会的法定使命,并通过使用基金会的知识价值和更广泛的影响审查标准进行评估,被认为值得支持。
英文摘要
Rivers and streams are a key component of the global ecosystem. Human alteration and pollution have made many of them no longer able to provide full ecological services and functions. In recent years, substantial efforts have been invested in restoring rivers and streams to improve their health, promote biodiversity, and increase resiliency. Among many restoration solutions, those mimicking how Nature works are increasingly employed, e.g., the re-introduction of wood into rivers and streams. However, the knowledge base for these nature-based solutions can be enhanced by improved scientific understanding on the physical processes around restoration structures. A principal objective of this research is to improve the knowledge base for nature-based approaches for river and steam restoration. The research approach to be used in this work utilizes state-of- the-art computing technology which makes it feasible to resolve the complex geometry of the restoration structures. It is anticipated that this project will reveal the physical processes around and within restoration structures. The understanding of physical processes is critical to successful implementation of nature-based solutions. Ecologically functional rivers and streams add great socio-economic value to the communities living around them.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
