SGER: Effects of Dam Removal on Riverine Habitats and Nutrient Retention

本研究提供了一个难得的机会来研究大坝拆除对物理环境和生物地球化学过程的影响，包括人为干扰影响、生态演替、沉积物运输和营养物质保留。这是一个知之甚少的地区，几乎没有可靠的数据，该项目将利用威斯康星州巴拉博河最近和即将进行的大坝拆除，这是美国最长的河流，恢复了自由流动的条件。该项目将获得对了解和管理水坝和水坝拆除至关重要的信息。该研究通过解决河流系统功能的概念生态模型，以及人为结构变化如何随着时间的推移演变成更自然的湿地栖息地，将基础科学与管理目标结合起来。本项目建立的模型对河流管理和生态演替理论的发展具有广泛的适用性。

Stanley 0108619 - This research offers a rare opportunity to investigate the effects of dam removal on the physical environment and biogeochemical processes, including anthropogenic disturbance impacts, ecological succession, sediment transport, and nutrient retention. This is a poorly understood area with little reliable data, and the project will capitalize on recent and upcoming dam removals in Wisconsin's Baraboo River, the longest river restored to free-flowing conditions in the Unites States. The project will obtain information critical to understanding and managing dams and dam removals. The study unites basic science with management objectives by addressing conceptual ecological models of riverine system function, and how anthropogenic structural alterations evolve over time into more natural wetland habitats. The models developed during this project have broad applicability for river management and the advancement of ecological succession theory.
