Unlocking the secrets of the groundwater cycle using Si and Li isotopes

该项目旨在确定如何使用创新的源到目标方法来使用非常规锂和硅同位素来了解地下水过程。该项目的目的是应用这些同位素示踪剂追踪一个井约束系统内的水循环：一个岛屿含水层，有一个密集的井田，已使用传统的同位素技术进行了分析。支持水化学数据将用于确定同位素与环境过程的关系。该项目的影响将是开发新的方法，以帮助了解我们的地下水资源。对过程的更好理解将转化为一般的地下水管理。 这些项目的重点是澳大利亚南部、东部和西部沿海地区典型的碳酸盐含水层系统，这将与珀斯等城市地区和农村地区的地下水管理有关，以促进旅游业和葡萄栽培，并管理国家公园的自然资源。

This project aims to determine how non-conventional lithium and silicon isotopes can be used to understand groundwater processes using an innovative source-to-target approach. The project aims to apply these isotope tracers to trace the water cycle within a well constrained system: an island aquifer with a dense borefield which has been analysed using traditional isotopic techniques. Supporting hydrochemical data will be used to determine the relationship of the isotopes with environmental processes. The project impact will be the development of new methods to help understand our groundwater resource. The improved process understanding will be translated to groundwater management in general. The projects' focus on carbonate aquifer systems typical of coastal regions of southern, eastern and western Australia will have relevance to groundwater management in urban areas such as Perth and in rural areas for tourism and viticulture, and for management of natural resources in National Parks.
