A persistent challenge in integrated water management is the ability to accurately evaluate human and ecological tradeoffs. Two-dimensional (2D) hydraulic models are frequently used to evaluate water management alternatives concerning aquatic species physical habitat needs or preferences. Recent studies have assessed the timing or duration of suitable habitat conditions, but no standardized approach exists to integrate and interpret ecohydraulic model outputs within a water management framework. Such an approach is needed to maximize the information obtained from model outputs and to facilitate communication between river scientists and water managers. This study presents a general framework to aggregate and summarize 2D hydraulic model outputs by adapting the traditional water resources metrics of reliability, resilience, vulnerability, and sustainability. Just as these metrics are typically used to quantify distinct aspects of water resources performance, applying them to ecohydraulic conditions facilitates interpretation of ecological performance and human-ecosystem water management tradeoffs. This paper examines the utility and limitations of the proposed framework and metrics in a simple application to fall-run Chinook salmon in a typical Mediterranean-montane stream.

集成水管理中的一项持续挑战是准确评估人与生态权衡的能力。经常使用二维（2D）水力模型来评估有关水生物种实际栖息地需求或偏好的水管理替代方案。最近的研究评估了合适的生境条件的时间或持续时间，但是在水管理框架内尚没有标准化的方法来整合和解释生态水力模型的输出。需要这种方法来最大化从模型输出中获得的信息，并促进河流科学家与水管理者之间的交流。这项研究提出了一个通用框架，通过适应传统的水资源指标（如可靠性，适应性，脆弱性，和可持续性。正如这些指标通常用于量化水资源绩效的各个方面一样，将其应用于生态水力条件也有助于对生态绩效和人类生态系统水管理权衡的解释。本文研究了在简单的典型地中海山地溪流中的奇努克鲑鱼的简单应用中，提出的框架和指标的实用性和局限性。
