河流廊道整合了活动河道、地貌洪泛平原和河岸区以及潜流带，同时接受来自高地和地下水的输入，并与大气进行质量和能量交换。本文从地貌学、水文学、生态学和地球化学的角度，回顾了当代对河流廊道认识的发展。然后，我们总结了当代模型的河流走廊沿着多个轴，包括空间和时间的维度，干扰制度，连接，水化学交换流量，和人类的遗产影响。我们探讨了如何河流廊道科学可以通过超越主要关注基于排放的控制向多因素模型，确定主导过程和阈值，使预测服务于社会的关键区框架。然后，我们确定的机会，调查大规模的空间梯度和局部尺度的过程之间的关系，拥抱河流过程是随时间变化和相互作用，承认河流走廊的过程和服务不尊重学科界限，越来越需要综合多学科的调查，并明确整合人类及其管理行动的河流走廊的一部分。我们打算我们的审查，以刺激跨学科的研究，同时认识到，河流走廊在地球表面占据独特的位置。
River corridors integrate the active channels, geomorphic floodplain and riparian areas, and hyporheic zone while receiving inputs from the uplands and groundwater and exchanging mass and energy with the atmosphere. Here, we trace the development of the contemporary understanding of river corridors from the perspectives of geomorphology, hydrology, ecology, and biogeochemistry. We then summarize contemporary models of the river corridor along multiple axes including dimensions of space and time, disturbance regimes, connectivity, hydrochemical exchange flows, and legacy effects of humans. We explore how river corridor science can be advanced with a critical zone framework by moving beyond a primary focus on discharge-based controls toward multi-factor models that identify dominant processes and thresholds that make predictions that serve society. We then identify opportunities to investigate relationships between large-scale spatial gradients and local-scale processes, embrace that riverine processes are temporally variable and interacting, acknowledge that river corridor processes and services do not respect disciplinary boundaries and increasingly need integrated multidisciplinary investigations, and explicitly integrate humans and their management actions as part of the river corridor. We intend our review to stimulate cross-disciplinary research while recognizing that river corridors occupy a unique position on the Earth's surface.
