Lifeline infrastructure - for example, bridges, dams, flood defences, ports, marine wind farms etc - in river, costal or marine environments is subjected to complex loading regimes arising through combinations of hydrodynamic and geotechnical effects. River or tidal currents and waves may induce structural loadings and sedimentological and / or geotechnical responses that can ultimately lead to severe damage or structural failure. Changing patterns of climate and infrastructure use mean that the compound effect of potentially two or more destabilising mechanisms is becoming increasingly complex and difficult to predict. However, despite their critical role in the resilience of lifeline infrastructure systems, these complex interactions remain largely under-researched. The resulting lack of understanding may lead to unnecessary costs or preventable failure of vital pieces of infrastructure. The aim of this project is to develop REAL, a novel experimental facility that will revolutionise research in submerged infrastructure by enabling comprehensive multi-phenomena testing. Creation of this unique facility will require the purchase of equipment comprising a large tilting flume, systems for water pumping and storage, wave generation and absorption, sediment feeding, recirculation and separation and instruments for detailed measurement of water velocities. These systems will be fully integrated and automated to reproduce scenarios representative of real-world conditions at unprecedented levels of realism. The research enabled by the facility will pave the way to novel approaches to the design and construction of future infrastructure systems that are both resilient and cost effective.

河流、沿海或海洋环境中的生命线基础设施（例如桥梁、水坝、防洪设施、港口、海上风电场等）要承受由水动力和岩土工程效应组合产生的复杂负载状况。河流或潮汐流和波浪可能会引起结构荷载以及沉积学和/或岩土响应，最终可能导致严重损坏或结构失效。气候和基础设施使用模式的变化意味着两种或多种潜在不稳定机制的复合效应变得越来越复杂且难以预测。然而，尽管它们在生命线基础设施系统的弹性方面发挥着关键作用，但这些复杂的相互作用在很大程度上仍然没有得到充分研究。由此产生的缺乏了解可能会导致不必要的成本或重要基础设施的可预防故障。该项目的目的是开发 REAL，这是一种新型实验设施，它将通过实现全面的多现象测试，彻底改变水下基础设施的研究。创建这一独特的设施需要购买包括大型倾斜水槽、抽水和储存系统、波浪产生和吸收、沉积物供给、再循环和分离系统以及用于详细测量水流速度的仪器等设备。这些系统将完全集成和自动化，以前所未有的真实度再现代表现实世界条件的场景。该设施开展的研究将为设计和建造未来基础设施系统的新方法铺平道路，这些系统既具有弹性又具有成本效益。
