Intermittent streams exhibit regular patterns of drying and are widespread, but the patterns of drying among streams within geographic proximity are not fully understood. We compared annual patterns of flow and drying among 10 intermittent streams within a single drainage basin and assessed how traditional hydrologic metrics described variation between streams. We installed stream intermittency sensors and evaluated stage height using low‐cost methods and evaluated landscape factors as potential drivers of flow patterns. Intermittent streams varied based on both high‐ and low‐flow metrics, driven by a variety of landscape‐level factors, especially watershed size. Additionally, we compared the observed flow regimes within our system with predictions generated using an established Soil and Water Assessment Tool, finding that modeled streamflow patterns generally underrepresented observed drying within the system.

干燥、更干燥、最干燥：区分间歇梯度上的流动模式

间歇性溪流表现出有规律的干燥模式并且分布广泛，但地理邻近的溪流之间的干燥模式尚不完全清楚。我们比较了单个流域内 10 条间歇性溪流的年度流量和干燥模式，并评估了传统水文指标如何描述溪流之间的变化。我们安装了水流间歇传感器，使用低成本方法评估了舞台高度，并评估了景观因素作为水流模式的潜在驱动因素。间歇性溪流根据高流量和低流量指标而变化，受到各种景观因素（尤其是流域大小）的驱动。此外，我们将系统内观察到的流动状况与使用现有的土壤和水评估工具生成的预测进行比较，发现建模的水流模式通常不足以代表系统内观察到的干燥。
