Scammonden dam has been described as a unique structure with its large embankment not only forming part of the M62 motorway but also impounding a reservoir. This paper presents the recollections and reflections on this huge project from the viewpoint of its two authors who were present on the site for most of the construction period; one of the authors, who is a Highway Engineer, was the Materials Engineer for the main contractor, Sir Alfred McAlpine & Son, and the other author, who is a Geotechnical Engineer, was much involved with some of the instrumentation. The important role of the contractor in sourcing materials for the embankment is described. Each author made a significant contribution in a sequence of events which arose towards the end of embankment construction. This began with identifying an issue relating to the extremely high pore-water pressures in the clay core and then in a preliminary assessment of the effect of this on upstream slope stability during the early stages of reservoir impounding.

Multipurpose large dams play a significant role in the development of world by providing water for irrigation, flood control and hydropower. This study aims to evaluate different strategies for the evacuation of deposited sediments and reducing sediment inflows to Tarbela Reservoir by using HEC-RAS. Sediment flushing from existing power tunnels was found unfeasible due to the downstream constraints and the loss of 7848 MW of hydropower. New sediment bypass tunnels on the right bank of the dam to overcome the constraints were analysed. The sediment balance ratio, long-term capacity ratio and economic analysis were computed along with sediment modelling for different scenarios. The most technically viable scenario was 90 days flushing at 390 m drawdown level with a discharge 5000 m3/s. This scenario was not economically feasible as NPV was negative, IRR was 3-4 %, and the benefit cost ratio was less than one. The Diamer Basha Dam under construction upstream of Tarbela Reservoir was also evaluated. The results suggested a large volume of sediment would be trapped in the upstream reservoir which would ultimately lead to a significant reduction in the inflow of sediment and the delta movement in Tarbela Reservoir. This option was recommended due to its multiple benefits and potential capacity to enhance Tarbela Reservoir's life.

The 2022 Binnie lecture was delivered to the British Dam Society on 16 September 2022. I began by looking at my introduction to reservoirs as a teenager. I then reviewed a variety of reservoir projects that have impacted my career and, more particularly, how they were shaped by social and environmental issues. Finally, I examined how my experience can influence the future of dam building in the UK.

Liquefaction is a phenomenon in which soil loses its bearing capacity, large settlements occur, and it may cause lateral spreading and failures. Numerous studies and cases in the world have shown that liquefaction occurs in the alluvium foundations of earth dams. The occurrence of widespread liquefaction can cause the entire dam to fail. In this paper, methods of assessment and numerical analysis have been used to assess the Shourijeh reservoir dam liquefaction. According to the latest criteria, it was observed that by considering the acceleration of the maximum credible earthquake level (MCE), the alluvial foundation of Shourijeh Dam is liquefiable in some areas. The dynamic analysis and liquefaction modelling based on linear equivalent analyses have been used. By analysing the sliding block and sliding circles based on the limit equilibrium method and the Newmark sliding block analysis, the stability safety factors of slopes for Shourijeh Dam after the earthquake have been investigated for three different earthquakes and various states of reservoir water level. Stress redistribution analysis has been used to estimate the permanent deformation of the structure due to seismic loading. The results of this research, in addition to providing helpful information regarding the performance of earth dams against liquefaction and its effects, have shown that the settlements caused by liquefaction in the studied dam are not so large that they would cause extensive damage and collapse of the dam at the MCE level.

Radar interferometry (InSAR) is a satellite remote sensing technique which offers deformation monitoring at frequent intervals with sub-centimetre accuracy. The most popular form of InSAR monitoring for infrastructure is Persistent Scatterer Interferometry (PSI). This relies on the identification of persistent scatterers: permanent, rigid objects which can reliably backscatter a signal to the satellite receiver. As the typical UK embankment dam has grassed slopes, the majority of persistent scatterers are detected at hard infrastructure located at the dam crest. The aim of this paper is to study the influence of dam features on persistent scatterer detection and quality at Scottish Water embankment dams. Following a case study in which PSI can be shown to detect dam deformation associated with an extreme climate event (the summer 2018 heatwave), statistics from 17 Scottish embankment dams are used to determine which dam features lead to the best quality PSI results. The type of wave protection at the crest of a dam is the biggest influence, whereas the presence of an asphalt surfaced crest road is shown to have a surprisingly limited effect on persistent scatterer quality.

Redundant reservoirs, whether they are subject to the provisions of reservoir legislation or not, have an ongoing maintenance requirement that places a burden on reservoir owners. Reservoirs upstream of communities also pose a risk to life. For these reasons, reservoir owners often consider discontinuing redundant assets; however, reservoirs can deliver amenity value for local communities as well as contributing to a desirable environmental habitat. Careful consideration should therefore be given to balancing the advantages and disadvantages when deciding whether to discontinue a reservoir. This paper will draw on case studies of five Scottish Water reservoir sites where the merits of discontinuance have been assessed. Two have been retained; and three have been discontinued. Key influences and lessons learned will be presented including identifying and mitigating environmental aspects; the findings from public consultations; the approach to whole life cost estimates; the benefits or otherwise of carrying ground investigations; the approach to dealing with sediment issues; the approach to managing flood risk during removal of the reservoir; and the approach to managing downstream flood risk following removal of the reservoir. The peculiarities of the Reservoirs (Scotland) Act 2011 (HMG, 2011) will be touched upon, as complete removal of a reservoir is termed abandonment!

The design of concrete dams for cold climates has its specific features. Particularly, the operation of dams is characterised by openings of horizontal construction joints on the downstream face due to significant temperature differences over the winter period between the downstream surface and the interior of the dam. The opening of joints increases further due to the changes in the thermal properties of concrete as it freezes. The effect of thermal stresses may induce the growth of tensile stresses on the upstream face because the dam decreases its profile. Thus, there is a problem of the effectiveness of reinforcement of the dam's downstream face. Numerical models that were developed made it possible to evaluate the strain state of a typical cross section of a gravity dam by (i) considering changes in the properties of concrete as it freezes; (ii) excluding changes in the properties of concrete; and (iii) considering changes in the properties of concrete plus reinforcement of the dam faces. As a result of this research, it has been possible to assess the actual stress-strain state of the downstream face of the dam (the average depth/width of joints openings) and evaluate changes of concrete properties at subfreezing temperatures.

Geophysics has become a fundamental tool for the characterisation of dam structures and the identification of subsurface defects. However, evolving a geophysical technique to a monitoring solution for observing subsurface water flow is considered an important step to help water companies and governing bodies achieve their aims related to climate resilience, water supply targets and for lengthening the design life of critical infrastructure. The paper shows how monitoring of Self-Potential (SP) voltages using the SPiVolt system developed by TerraDat has successfully mapped water flow through the downstream shoulder of a Victorian-era embankment dam, and how these water flow paths responded to changes reservoir level and weather events such as heatwaves and rainfall. The study has also shown the importance of using a multi-technique geophysical survey to provide a wider context and deeper understanding of dam structures. The methodology described in this paper has the potential to not only provide a low-cost solution to monitoring embankment dams but can also be applied to numerous scenarios including landslide investigations, peatlands and flood defences.

Infrared thermography measurements are more and more frequently performed in order to diagnose the technical condition of buildings, and they can also be applied to hydraulic structures. The paper demonstrates that thermography may be used for detecting the location of places of increased seepage. The paper also presents examples of thermograms of surface damage of concrete surfaces and leakages through hydraulic structures.
