Ecohydrologic functioning of ephemeral streams

该项目旨在增加对地表-地下水相互作用如何维持与短暂河流相关的植被的理解。干旱地区采矿和区域开发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，加上植被用水评估和数字建模，以评估短暂河流对采矿活动造成的流量变化和与气候有关的补给变化的适应能力。该项目的预期成果包括为评价和调整管理以保护稀缺水资源提供适当的背景。这一项目将大大有助于矿物和地下水资源的可持续管理。

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.
