The 2013 RARS (Risk Assessments for Reservoir Safety management) guidance was developed for the Environment Agency to provide a robust three-tiered framework for the risk analysis, assessment and management of reservoirs in the UK. The methods presented can be used to assess a reservoir's risk in its entirety, either at a qualitative level (Tier 1) or more in-depth quantitative levels (Tier 2 and 3). Binnies undertook RARS assessments of reservoirs for Hong Kong's Water Supply Department (WSD). This paper identifies the limitations and challenges encountered when applying the guidance in Hong Kong, beyond its original intended purpose. It outlines the adjustments made to assess the Hong Kong service reservoirs at Tier 1, and large embankment and gravity dams at Tier 2. Some of the differences include (1) how the nature of loading and external threats differs due to geographical and locational differences; (2) how consequences of reservoir failure differ due to topology, population densities, and cultural differences in the reservoirs’ uses, and (3) how the reservoirs are atypical from ‘Pennine’ type UK embankment dams, from which most UK empirical methods are derived.

Discontinuance of reservoirs, particularly those retained by aging embankment dams, is becoming a common option for water companies who no longer need these assets for their water supply network (Carter, 2022). This paper will examine the discontinuance of Dunside Upper and Lower Reservoirs, describing the novel aspects of the project, along with the method of project delivery, and how they contributed towards the success of the project. It will also describe the process for removal under the Reservoirs (Scotland) Act 2011, which in the case of complete removal of the reservoir is termed abandonment.

As flood risk authorities look to counter increasing peak river flows due to a changing climate, traditional linear flood defences are in many cases proving to be an unsustainable method of managing flood risk. Full containment of flows in the river channel will require ever increasing defence heights, cutting off communities from their rivers and natural heritage. Upstream flood storage provides a potential alternative means of flood management, allowing the peak of the flood to attenuate and downstream river levels to be kept within a tolerable range. The Leeds Flood Alleviation Scheme Phase 2 (FAS2) uses a combined approach: linear defences are constructed in urban reaches and complemented by an online flood storage reservoir (FSR) upstream of the city. The FSR halves the annual probability of defences overtopping within the city centre from 1% to 0.5%, achieved through active variable flow control at the FSR. This paper explores some of the challenges faced in the design and construction the in-river flow control structure which is integral to the operation of the FSR. In particular this paper will consider some of the key environmental objectives for the scheme and offer considerations for working in a dynamic and environmentally sensitive fluvial environment.

The Canal and River Trust, undertaker for 71 high-risk reservoirs, has developed a schedule to conduct a desktop test annually and a full incident simulation exercise every five years. The paper covers the methodology for developing the desktop test, integrating international best practices and strategies from other industries. Practical insights for effectively conducting a desktop exercise, ranging from the selection of failure mode scenarios to debriefings, are provided. The importance of a full simulation was highlighted following the Toddbrook incident. The paper describes how to organise a simulation exercise and the considerations for selecting a suitable reservoir, based on access, location, stakeholders, failure mode and risk assessments on the backdrop of ‘Operation Redbrook’ conducted in June 2023. Pre-exercise arrangements include failure mode simulation, welfare, weather warnings, media responses and traffic management. The Trust also engaged the Local Resilience Forum, BT Emergency services and the contractor's supply chain. The challenges faced by contractors in deploying emergency pumps raises questions on proportionality of expenditure for crane pads, assessments for utilities, environmental impacts and traffic management. Strategies to disseminate lessons learnt and continuous improvement of the emergency response system within the Trust are covered.

This study aims to evaluate the earth dam stability fuzzy model based on the pace of construction via influential parameters, including the dam construction time (embankment consolidation time) in the stability analysis of earth dams. A fuzzy inference system based on the Sugeno inference engine was developed, and 620 IF-THEN rules in PLAXIS (Plane Strain and AXIal Symmetry). were used to train the fuzzy system. The input parameters included the dam height, crest width, dam slope, cohesion, friction angle, elasticity modulus, Poisson's ratio, unsaturated unit weight, consolidation (construction) time, and permeability coefficient, with the Factor of Safety (FoS) output. To develop the fuzzy inference system, a triangular membership function (MF) was employed, calculating the influential parameters over five periods in MATLAB (MATrix LABoratory) software. The fuzzy model results were compared to the results of numerical PLAXIS and FLAC (Fast Lagrangian Analysis of Continua) models. The coefficient of determination (R2) was found to be 0.9824 for the PLAXIS and fuzzy model analyses and 0.9753 for the FLAC and fuzzy model analyses. This suggests good agreement between the fuzzy and numerical models, and it can be assumed that the proposed fuzzy model is efficient and effective for the stability analysis, and hence assessment of factors of safety, of earth dams.

Puddle clay core embankment dams were built prior to the use of rolled clay core dams and comprise a large proportion of UK dams, the dams relying for their watertightness on adding water to (puddling) the clay until it had an undrained shear strength of around 10kPA, and thus had increased ability to deform without cracking. Such dams sometimes had early forms of unfiltered drains, comprising coarse cobbles, in the downstream shoulder, either to assist construction, and/or to lower the phreatic surface and improve slope stability once the reservoir was in operation. These drains are separate from foundation drains dealing with springs encountered in the foundation excavation and drains to deal with surface runoff. This paper gives examples of such drains in dams constructed between 1863 and 1940. These drains were installed prior to the development of classic filter design rules and tools to analyse seepage. This is important as the drains have no filter, and are thus vulnerable to internal erosion which, if not detected, could lead to failure of the dam. These drains may also be the true root cause of historic incidents at these dams, due to embankment fill materials washing into the drain and creating sinkholes.

In 1937 the investigation of the failure during construction of Chingford No 2 embankment dam brought the concepts of modern soil mechanics to bear on the construction of British embankment dams. Effective stress theory highlighted the crucial significance of pore water pressure in understanding embankment stability and it became standard practice to monitor pore pressures during embankment construction using twin-tube hydraulic piezometers. By the 1980s embankment stability might have seemed assured, with embankment design utilising limit equilibrium stability analyses that incorporated strength parameters of fill and foundation materials determined by laboratory testing. However, in 1984 the upstream slope of Carsington dam suffered a major slip in the final stage of construction. Recently developed advanced finite element analyses were able to demonstrate that progressive failure was a major factor in the slope instability, but the failure was also a reminder of the continuing need for experience-based judgement in design.

Understanding flood risk perceptions is critical for effective flood risk communication. In 2019, heavy rainfall triggered the failure of Toddbrook Reservoir's spillway resulting in a severe flood warning being issued for the Whaley Bridge area. In 2022, a large-scale restoration began at the reservoir. This paper describes perceptions of reservoir flood risk by the residents of Whaley Bridge and experts in environmental science and engineering. Results show that risk perception varies, with residents perceiving reservoir flood risk subjectively and experts perceiving risk objectively. With no previous risk communication, residents did not consider there to be a risk of reservoir failure; moreover, they have trust in Toddbrook's restoration. Meanwhile, experts emphasize that risk can never be fully eliminated, but that the probability of failure is extremely low. Climate change is considered by some as a contributing factor to the event and uncertainties in the risks that it poses has meant that there is a requirement to improve and maintain existing dams to mitigate risk. Findings have demonstrated the importance of more advanced risk communication as well as a necessity to improve flood risk maps for accessibility, awareness and to better account for the probability of failure in order to avoid the misinterpretation of risk. By identifying differing perceptions of risk between experts and residents, data results can be used to enhance reservoir risk communication. This paper is based on the author's undergraduate thesis titled ‘Restoring with Risk: Perceptions of Reservoir Flood Risk in Whaley Bridge’ at Bath Spa University in 2023.
了解洪水风险认知对于有效的洪水风险沟通至关重要。2019 年，暴雨引发 Toddbrook 水库溢洪道溃坝，导致 Whaley Bridge 地区发布严重洪水预警。2022 年，水库开始进行大规模修复。本文介绍了惠利桥居民和环境科学与工程专家对水库洪水风险的看法。结果显示，风险认知存在差异，居民对水库洪水风险的认知是主观的，而专家对风险的认知是客观的。由于之前没有进行过风险交流，居民并不认为存在水库溃坝的风险；此外，他们还对 Toddbrook 的修复工作表示信任。同时，专家强调，风险永远不可能完全消除，但溃坝的可能性极低。一些人认为气候变化是导致溃坝的一个因素，而气候变化带来的风险的不确定性意味着需要对现有大坝进行改进和维护，以降低风险。研究结果表明，进行更先进的风险交流非常重要，同时有必要改进洪水风险地图，以提高可访问性和认知度，并更好地考虑溃坝概率，从而避免对风险的误读。通过识别专家和居民对风险的不同认识，数据结果可用于加强水库风险交流。本文基于作者于 2023 年在巴斯斯帕大学完成的本科论文 "Restoring with Risk: Perceptions of Reservoir Flood Risk in Whaley Bridge"。
