在过去30年中，强降雨的频率和发生率以及由此产生的极端水文事件-洪水-稳步增加。英国的排水基础设施不是为气候变化而设计的，人口稠密的城市地区的许多下水道系统无法科普。城市地区的污水溢出和地表径流可成为病原体传播的媒介，已知病原体会在人群中引起疾病。该领域以前的大多数研究都集中在使用粪便指标，如大肠杆菌，评估洪水的公共卫生风险[1]。然而，传统的指标并不能准确反映城市洪水造成的真正风险[2]。人们对病原体在不同城市环境中的生存能力和行为知之甚少，而这对于确定公共卫生的潜在风险至关重要。英国涝渍土壤中的先前研究表明，微生物群落对土壤剖面中的地下水位变化、温度和养分有效性有明显的响应[3]。本研究旨在使用先进的分子方法，调查病原体的动态（即通过土壤和存活率的运动），以及土壤/水界面的微生物相互作用-从实地工作研究和实验室控制实验中收集信息。这项研究的结果将为未来的洪水遗址管理策略提供信息，这将有助于保护公众健康。参考文献[1] Yard等人，2014.

Over the last 30 years, the frequency and occurrence of intense rainfall, and thus extreme hydrological events –flooding- has steadily increased. Drainage infrastructure in the UK was not designed for a changing climate, and many sewer systems in densely populated urban areas, are unable to cope. Sewage overflow and surface run off in urban areas can act as vectors for the dissemination of pathogens, known to cause disease among human populations. Most of the previous studies in this field have focused on using faecal indicators such as E.coli when assessing the public health risk of floodwater [1]. However, traditional indicators do not accurately reflect the true risk that urban flooding poses [2]. Little is understood in regards to the survivability and behaviour of pathogens in different urban settings, which are fundamental to determine potential risks to public health. Previous investigations in UK waterlogged soils have shown a clear response of microbial communities to water table variation, temperature, and nutrient availability in soil profiles [3]. This research aims to investigate, using advanced molecular methods, the dynamics of pathogens (i.e. movement through soil and survival rates), and microbial interactions at the soil/water interface- collecting information from field work studies and laboratory-controlled experiments. The outcomes from this research will inform future management strategies of flooded sites that will aid to protect public health. References [1] Yard et al., 2014. J. Environ. Sci.
