Proper understanding of soil-water interaction is vital for sustainable development of floodplains, and to halt acid mine drainage caused by the oxidation of pyritic soil. Permeable reactive barriers (PRB) offer a cost-effective solution to neutralize acidified groundwater. The project aims to quantify the clogging potential of PRB’s granular medium by coupling geotechnical fundamentals with integrated hydro-bio-geochemical processes. Time-dependent clogging will be evaluated through geotechnical laboratory & field testing. Expected outcomes are enhanced PRB design methods and sound geotechnical field monitoring to provide significant industry benefits, such as mine-site rehabilitation, increased productivity and infrastructure longevity.

正确认识水-土相互作用对洪泛平原的可持续发展和防治黄铁矿氧化引起的矿山酸性排水具有重要意义。渗透性反应屏障（PRB）为酸化地下水提供了一种经济有效的解决方案。该项目旨在通过将岩土技术基础与综合水文-生物地球化学过程相结合，量化PRB颗粒介质的堵塞潜力。时间依赖性堵塞将通过岩土实验室和现场测试进行评估。预期结果是增强PRB设计方法和良好的岩土现场监测，为行业带来重大效益，如矿山现场修复、提高生产率和基础设施寿命。
