This exciting PhD project, in collaboration with Northumbrian Water, will investigate the impact of climate change on river water quality, the implications this will have for water treatment infrastructure, and novel engineering interventions for management of such impacts. A specific focus for the research will be water treatment infrastructure resilience to changes in freshwater sulphate concentrations; freshwater sulphate concentrations have increased in recent decades, and these problems are particularly evident in former mining catchments, including in north-east England. The project will involve (1) reviewing regional / national trends in freshwater sulphate concentration to identify water infrastructure at potential risk, now and in the future, (2) quantifying current (point and diffuse) sources of sulphate in legacy coal mine catchments, (3) projecting future riverine sulphate concentration and flux using NU's SHETRAN modelling software, (3) trialling innovative, catchment-based management approaches to sulphate source control, and water treatment plant-based technologies for sulphate attenuation. The project will involve close working with Northumbrian Water, as well as the Newcastle University academic supervisors. Research will be conducted at national, regional and local scales. Fieldwork (water quality and hydrology) will focus on the River Wear, NE England, with associated analysis work in the University's well-equipped labs. The project will involve numerical modelling work, and some prior knowledge in this area would be advantageous.

这个令人兴奋的博士学位项目与诺森比亚水合作将调查气候变化对河水质量的影响，对水处理基础设施的影响以及对这种影响的管理的新型工程干预措施。该研究的特定重点是水处理基础设施对淡水硫酸盐浓度的变化的弹性；近几十年来，硫酸盐浓度升高了，这些问题在以前的采矿集水集中尤为明显，包括英格兰东北部。该项目将涉及（1）审查硫酸盐浓度的区域 /国家趋势，以识别现在和将来的潜在风险水基础设施，（2）量化传统煤矿集水区中硫酸盐的当前（点和分散）来源（ 3）使用NU的Shetran建模软件预测未来的硫酸盐浓度和通量，（3）试验的创新，基于集水的管理方法，用于硫酸盐源控制，以及用于硫酸盐衰减的水处理植物处理技术。该项目将涉及与诺森比亚水以及纽卡斯尔大学的学术主管密切合作。研究将在国家，地区和地方规模进行。现场工作（水质和水文学）将重点关注英格兰NE的河磨损，并在大学设备齐全的实验室中进行相关的分析工作。该项目将涉及数值建模工作，并且该领域的一些先验知识将是有利的。
