CAREER: Improving the science and practice of restoration with hydroecologic observatories

[0954499] loheide这个项目正在开发一种连续监测土壤水势的新方法。该方法将使用分布式温度传感技术，将埋地光缆的热脉冲引起的热响应与土壤水势联系起来。三维的、可变饱和的地下水流动模型将在空间和时间上扩展已经广泛的野外数据，以便可以估计过去气候条件下的水文生态位。利用这些知识，将创建一个耦合的植被和水文建模框架，以便定量预测植被组成和模式以及潜在恢复策略可能产生的水文反馈。利用本研究中产生的模型，可以在项目设计阶段预测通过恢复活动重建所需植被的程度，并为该地区的恢复从业者创建一套指导方针。该项目具有更广泛的影响，涉及改善河流恢复实践，并为中学生、本科生和研究生提供基于情境的教育机会。该奖项由工程学院的环境可持续性项目和地质学院的水文科学项目共同资助。

0954499LoheideThis project is on developing a new method for continuous monitoring of soil water potential. The method will use distributed temperature sensing technology by relating the heat pulse induced thermal response of a buried fiber optic cable to the soil water potential. Three-dimensional, variably-saturated groundwater flow modeling will be performed to extend in space and time already extensive field data so that hydrologic niches can be estimated for past climatic conditions. Using this knowledge, a coupled vegetation and hydrologic modeling framework will be created to enable quantitative prediction of the vegetation composition and patterning and hydrologic feedbacks that would result from potential restoration strategies. With the models produced in this study, the extent to which desired vegetation can be re-established by restoration activities will be able to be predicted during the design phase of projects and a set of guidelines will be created for restoration practitioners of the region. The project has broader impacts related to both improving the practice of river restoration and providing context-based educational opportunities to middle school, undergraduate, and graduate students. This award is co-funded by the Environmental Sustainability program in ENG and the Hydrologic Sciences program in GEO.
