Scientific Significance Statement

Low flows pose unique challenges for accurately quantifying streamflow. Current field methods are not optimized to measure these conditions, which in turn, limits research and management. In this essay, we argue that the lack of methods for measuring low streamflow is a fundamental challenge that must be addressed to ensure sustainable water management now and into the future, particularly as climate change shifts more streams to increasingly frequent low flows. We demonstrate the pervasive challenge of measuring low flows, present a decision support tool (DST) for navigating best practices in measuring low flows, and highlight important method developmental needs.

你能降到多低？测量低流量流量的广泛挑战和前进的道路

科学意义声明

低流量对准确量化水流提出了独特的挑战。目前的现场方法并未优化以测量这些条件，这反过来又限制了研究和管理。在本文中，我们认为缺乏测量低流量的方法是确保现在和未来可持续水管理必须解决的一个根本挑战，特别是在气候变化使更多的溪流转向越来越频繁的低流量的情况下。我们展示了测量低流量的普遍挑战，提出了用于导航测量低流量最佳实践的决策支持工具 (DST)，并强调了重要的方法开发需求。
