蓄流关系和蓄水连通性的动态变化仍然是理解和预测流域行为的关键未知因素。在这项研究中，我们使用全球定位系统对负荷引起的地表位移的测量作为美国西部四个气候不同的山区流域总蓄水量变化的替代。将总蓄水量估算与由过程线分析得出的分流蓄水量进行比较，我们发现，每个调查流域的总蓄水量与分流蓄水量之间都呈现出一种特有的季节连接和断开模式。我们研究了流域尺度连通性的程度和时间与降水时间和主导水文过程的季节变化之间的关系。我们的结果表明，地球在水负荷下的弹性变形是阐明动态存储连通性和流域流量在空间和时间尺度上响应的强有力的新工具。
Storage-discharge relationships and dynamic changes in storage connectivity remain key unknowns in understanding and predicting watershed behavior. In this study, we use Global Positioning System measurements of load-induced Earth surface displacement as a proxy for total water storage change in four climatologically diverse mountain watersheds in the western United States. Comparing total water storage estimates with stream-connected storage derived from hydrograph analysis, we find that each of the investigated watersheds exhibits a characteristic seasonal pattern of connection and disconnection between total and stream-connected storage. We investigate how the degree and timing of watershed-scale connectivity is related to the timing of precipitation and seasonal changes in dominant hydrologic processes. Our results show that elastic deformation of the Earth due to water loading is a powerful new tool for elucidating dynamic storage connectivity and watershed discharge response across scales in space and time.
