This project aims to increase understanding of how surface-groundwater interactions sustain vegetation associated with ephemeral streams. One of the biggest problems faced by mining and regional development in arid regions is how to protect ecological and heritage values of ephemeral streams by minimising impacts of water abstraction and surplus discharge. The project will use environmental tracers, coupled with assessment of vegetation water use and numerical modelling, to assess resilience of ephemeral streams to changes in flows resulting from mining activities and climate-related shifts in recharge. Expected outcomes of the project include providing appropriate context for evaluating and adapting management to conserve scarce water resources. This project should significantly contribute to the sustainable management of both mineral and groundwater resources.

该项目旨在加深对地表-地下水相互作用如何维持与短暂溪流相关的植被的理解。干旱地区采矿和区域发展面临的最大问题之一是如何通过尽量减少取水和剩余排放的影响来保护短暂河流的生态和遗产价值。该项目将使用环境示踪剂，结合对植被用水的评估和数值模拟，评估短期溪流对采矿活动和与气候有关的补给变化造成的流量变化的适应能力。该项目的预期成果包括为评估和调整管理提供适当的背景，以保护稀缺的水资源。这个项目将大大有助于矿物和地下水资源的可持续管理。
