Urban flooding is caused by heavy rainfall and is a growing global challenge. Many cities are rethinking their approach to flood risk management by using green infrastructure (GI) and Nature-based Solutions (NbS) to complement traditional hard engineered approaches. GI, NbS and Sustainable Drainage Systems (SuDS) are a series of innovative and novel solutions and/or techniques to bring hydrological responses closer to pre-urbanised conditions. It is often difficult to determine the effectiveness of SuDS and this depends on both the magnitude of storm events and the spatial scale of the intervention. Further, monitoring of the successes and failures of SuDS schemes is not routinely conducted. Thus, it can be difficult to determine whether SuDS provide a sustainable solution to manage urban flooding. We need to collect a strong evidence base to maximise urban green infrastructure. This IAPETUS2 PhD project will address this critical research gap through the development of pioneering solutions to answer critical research questions within the field of green infrastructure and urban flood risk management. This PhD project will focus on the collection, analysis and interpretation of fieldmonitored data to assess and maximise bioretention performance of green infrastructure. The project will involve the design, commissioning and analysis of novel laboratory and field experiments based at Heriot-Watt University Edinburgh campus and within the City of Edinburgh. The PhD will also leverage two fullycommissioned, state-of-the-art instrumented vegetated bioretention cell lysimeters based at the UKCRIC National Green Infrastructure Facility (NGIF), with the opportunity to conduct discrete experimental tests on these systems. Further, there is scope to complement and upscale field approaches using hydraulic-hydrological modelling approaches (i.e. SWMM, HYDRUS-1D, etc.) to understand the impact of NbS at larger scales. This project will focus predominantly on the attenuation of surface water flows (i.e. flood risk reduction), but the project may also consider the influence of SuDS on water quality, biodiversity and public amenity. The successful candidate will be based at Heriot-Watt University's Edinburgh campus and will be required to visit the NGIF in Newcastle-upon-Tyne for experimental monitoring, maintenance and data collection approximately every 2- months. There will be opportunities to collaborate with international stakeholders and partners to realise the potential of NbS within different regions/climates.

城市洪水是由大雨引起的，是日益严重的全球挑战。许多城市正在通过使用绿色基础设施（GI）和基于自然的解决方案（NB）来重新思考其洪水风险管理方法，以补充传统的硬工程方法。 GI，NBS和可持续排水系统（SUD）是一系列创新和新颖的解决方案和/或技术，以使水文反应更接近前城化条件。通常很难确定SUD的有效性，这取决于风暴事件的大小和干预的空间量表。此外，没有常规地监视SUDS方案的成功和失败。因此，很难确定SUD是否提供了管理城市洪水的可持续解决方案。我们需要收集强大的证据基础，以最大程度地提高城市绿色基础设施。这个IAPETUS2博士学位项目将通过开发开拓性解决方案来解决这一关键研究差距，以回答绿色基础设施和城市洪水风险管理领域内的关键研究问题。该博士学位项目将集中于对现场对数据的收集，分析和解释，以评估和最大程度地提高绿色基础设施的生物性能。该项目将涉及在爱丁堡大学和爱丁堡市内的基于赫奥特瓦特大学的新型实验室和现场实验的设计，调试和分析。该博士还将利用基于UKCRIC国家绿色基础设施设施（NGIF）的两名全能，最先进的植被生物测定细胞裂解器（NGIF），有机会对这些系统进行离散的实验测试。此外，还有使用液压 - 流水学建模方法（即SWMM，Hydrus-1D等）进行补充和高档场方法的范围，以了解NBS在较大尺度上的影响。该项目将主要集中于地表水流的衰减（即减少洪水风险），但该项目也可能考虑SUD对水质，生物多样性和公共便利的影响。成功的候选人将位于赫里奥特大学的爱丁堡校园，并将被要求访问泰恩河畔纽卡斯尔的NGIF，以进行大约每2个月的实验监测，维护和数据收集。将有机会与国际利益相关者和合作伙伴合作，以在不同地区/气候内实现NB的潜力。
