Despite large advances in the state of the science of stream ecology and river mechanics, the practitioner-driven field of stream restoration remains plagued by narrowly focused projects that sometimes even fail to improve aquatic habitat or geomorphic stability-two nearly universal project goals. The intent of this article is to provide an accessible framework that bridges that gap between the current state of practice and a more geomorphically robust and ecologically holistic foundation that also provides better accounting of socioeconomic factors in support of more sustainable stream restoration outcomes. It points to several more comprehensive design references and presents some simple strategies that could be used to protect against common failure mechanisms of ubiquitous design approaches (i.e., regional curves, Rosgen planform, and grade control). From the simple structure design to the watershed-scale restoration program, this may be a first step toward a more geomorphically principled, ecologically holistic, and socioeconomically sustainable field.
尽管河流生态学和河流力学的科学水平取得了巨大进步,但由从业者主导的河流修复领域仍然受到一些专注度狭窄的项目的困扰,这些项目有时甚至未能改善水生栖息地或地貌稳定性,而这是两个几乎普遍存在的项目目标。本文旨在提供一个易于理解的框架,弥合当前实践状态与更具地貌稳健性和生态整体性的基础之间的差距,同时更好地考虑社会经济因素,以支持更可持续的河流修复成果。它指出了一些更全面的设计参考,并提出了一些简单的策略,可用于防范常见设计方法(即区域曲线、罗斯根河型和坡度控制)的常见失败机制。从简单的结构设计到流域尺度的修复计划,这可能是迈向更具地貌原则性、生态整体性和社会经济可持续性领域的第一步。
