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.

0954499 Loheide该项目旨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，通过将热脉冲引起的埋地光纤电缆的热响应与土壤水势相关联。 将进行三维、可变饱和地下水流模拟，以在空间和时间上扩展已经广泛的现场数据，从而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，使定量预测的植被组成和图案和水文反馈，将导致潜在的恢复战略。 利用本研究中建立的模型，在项目设计阶段就可以预测恢复活动能够在多大程度上重建所需植被，并为该地区的恢复工作者制定一套准则。 该项目具有更广泛的影响，既改善河流恢复的做法，并提供基于上下文的教育机会，中学，本科和研究生。 该奖项由ENG的环境可持续性计划和GEO的水文科学计划共同资助。
