Climatic conditions are changing, which affects dissolved organic carbon (DOC) in surface water. DOC is a precursor for the formation of unwanted disinfection by-products (DBPs) in drinking water treatment, which includes trihalomethanes (THMs). Scenarios for climate change impacts on THM formation suggest a 39% increase by 2050 for the British Isles unless treatment is adapted. This PhD project, led by Newcastle University, is in collaboration with Northumbrian Water, and will research proactive management of DOC in catchments to reduce loads into reservoirs and treatment works. Proactive management of DOC in catchments addresses the root cause of the THM challenge and reduces the costs, chemical and energy demands, and environmental impacts of water treatment. The project will review and evaluate nature-based mitigation measures for rising DOC in a case study catchment to develop and validate a catchment-scale DOC monitoring, modelling and management tool. The fieldwork will involve innovative monitoring tools to study DOC loads and characteristics with real-time sensing of water quality, incl. fluorescent dissolved organic matter (FDOM). This will build on experience with real-time water quality sensing systems of the National Green Infrastructure Facility and Newcastle University's Urban Observatory. The fieldwork will inform the development of a model for DOC management in catchments and in reservoirs to inform abstraction management and engagement with landowners. The project thus seeks to demonstrate a smart water infrastructure solution that combines sensing and modelling with nature-based approaches for climate change resilience and water security.

气候条件正在发生变化，这影响了地表水中溶解有机碳（DOC）。DOC是饮用水处理中形成不需要的消毒副产物（DBPs）的前体，其包括三卤甲烷（THMs）。气候变化对THM形成的影响的情景表明，到2050年，不列颠群岛的THM将增加39%，除非采取相应的治疗措施。这个博士项目，由纽卡斯尔大学领导，是在与诺森伯兰水合作，并将研究在集水区DOC的主动管理，以减少到水库和处理工程的负荷。对集水区DOC的主动管理解决了THM挑战的根本原因，并降低了水处理的成本、化学和能源需求以及环境影响。该项目将审查和评估案例研究流域DOC上升的自然缓解措施，以开发和验证流域尺度DOC监测，建模和管理工具。实地工作将涉及创新的监测工具，以研究DOC负荷和水质的实时传感，包括特性。荧光溶解有机物（FDOM）。这将建立在国家绿色基础设施和纽卡斯尔大学城市观测站的实时水质传感系统的经验基础上。实地工作将为流域和水库DOC管理模型的开发提供信息，以告知抽取管理和与土地所有者的接触。因此，该项目旨在展示一种智能水基础设施解决方案，该解决方案将传感和建模与基于自然的方法相结合，以提高气候变化的适应能力和水安全。
