Dams & Reservoirs Journal Special Edition for Spetember 2019 - Your Help Required

The September 2019 issue will be a special edition covering the digital agenda, including CFD and automation. During the most recent BDS Conference in Swansea, a workshop was held to discuss CFD modelling and its application to the dams’ industry. The workshop gave an opportunity for a number of CFD practitioners to demonstrate the state of play and encouraged discussion on the challenges in application of this tool to the dams’ industry. The majority of the attendees were not CFD practitioners and it was highlighted that there has been a lack of guidance for specifying and reviewing CFD modelling.

UK Reservoir Engineers Cited in Dam Inspection Special Feature of International Water Power & Dam Construction Publication

The Modern Dam Engineer article in the November editon of the International Water Power & Dam Construction Publication.

Like many industries, the dam industry is influenced by both internal and external factors which can prompt change. IWP&DC was interested in finding out if such elements have affected the engineer's working life when inspecting dams. We asked members of the industry for their own thoughts about the role of the modern dam engineer: Has this changed in recent years? Are engineers faced with increased challenges? And will this role continue to evolve?

Professor Paul Adrian Auchmuty Back CBE FREng FICE 1930 - 2017

It is with regret that we hear of the death of Professor Paul Back. 

He was born and educated in South Africa. He obtained a BSc at Cape Town University in 1951 and was awarded a Rhodes Scholarship to Oxford University (Trinity College) and obtained a DPhil (Engineering Science) in 1954.

Having graduated from Trinity College, Oxford (where he later became a Visiting Fellow) he joined Sir Alexander Gibb & Partners, a major consulting civil engineering firm, in 1955, becoming an associate in 1967 and partner in 1970.  He became chief technical director in 1989 when the firm merged with the American company Law (later acquired by Jacobs Engineering Group).

Initially he worked on the design of the Kariba Dam and subsequently joined the Gibb site staff in what was then Southern Rhodesia. Following his return to the UK he was involved with the design of the Latiyan Dam (Iran), major dams on the Orange River in South Africa, the Indus Basin Project, Victoria and Samonellaweewa dams in Sri Lanka, the Drakensberg Pumped Storage Project (South Africa), Katse Dam (Lesotho) and a number of other important hydroelectric dam projects including the Tongariro Hydroelectric Scheme in New Zealand and Lar Dam in Iran.

From 1992 to 1998 he was the Royal Academy of Engineering Visiting Professor in the Principles of Civil Engineering Design at the University of Oxford, a role previously held by ICE Past President Edmund Hambly. University staff recall that he was "a real gentleman, very civilised and thoughtful". During his time there, in 1993, he was asked to assess the Peruca Dam in Croatia which had been sabotaged by the Serbs in the Balkan war and which, if breached, would result in the deaths of 20,000 people in a city downstream. He decided that the dam, although damaged, would probably not fail and so the town did not need to be evacuated. In the event the dam held.

He joined the ICE in 1956 as a Graduate member, becoming a Member in 1962 and achieving Fellowship in 1971. He was elected as a Council member from 1989 to 1992 and became a Fellow of the Royal Academy of Engineering in 1981. He was awarded a CBE in 1994 for services to Dam Engineering in Developing Countries.

He made a major contribution to all of the projects with which he was involved not least because of his inventiveness and ability to find new technical solutions when the need arose.

He was an inspiration to the numerous young engineers who he helped in many ways.

 

Condition Assessment of Dams - Case Studies for Nottingham Trent University

Roland Kromanis is a lecturer at Nottingham Trent University who is delivering a new MSc module in Structural Engineering - Condition Assessment and Health monitoring of civil infrastructure.

He has realised that water supply reservoirs are critical national assets and he has therefore included the importance of the condition assessment of dams (including embankment dams) in the module.

Bateman Awards 2017

In 2000 the British Dam Society instituted an award to the authors of a paper which made a significant contribution to dam engineering or reservoir development.  Andy Hughes as Chairman at the time, and who was then managing the Longdendale Reservoirs for North West Water (now United Utilities) suggested the award after helping the late Geoffrey Binnie with his many books, and having developed a high regard for the engineering carried out by Bateman.

The award is named after the illustrious Victorian dam engineer John Bateman, and is given for a paper in which at least one of the authors is a member of the BDS.

John Frederic La Trobe Bateman was involved in the construction of reservoirs and waterworks through much of the 19th century, many of which were in northern England, but a number also in Scotland and Ireland.  These included the Loch Katrine works for Glasgow and the Thirlmere Scheme for Manchester.  A full obituary of Mr Bateman is available in the 1889 ICE Proceedings, and available here.

The Bateman Award is made every two years by a small panel of BDS members, with the papers considered having been published in the conference proceedings, as well as in all the issues of Dams and Reservoirs and any other relevant publications from the last two years.  The papers are assessed for technical content, originality and readability.  It is an award rather than a prize, and no nominations are required.

Each author receives a framed picture showing photographs of Mr Bateman and the Longdendale chain of reservoirs just north of Glossop which he designed and built.  A plaque on the frame gives the author's name. 

The panel for the current award comprised Andrew Pepper, Paul Farnell, Liz Rivers and Rachel Davies.  One paper was on everyone's short list, and when the combined short list of papers was scored that paper did indeed gain the highest mark.

That paper, which the panel felt made the most significant contribution to dam engineering or reservoir development in the last two years, was published in the Dams and Reservoirs issue dated August 2015 and was titled 'How prepared are we for a reservoir emergency?' by Gemma Morris and Stephen Shakespeare of Welsh Water.  It is recommended reading for all involved with reservoirs.

The authors were presented with their framed award pictures at the BDS evening meeting in London on 16 January 2017 by the BDS chairman, Dr Andy Hughes (photograph available here).

Autumn Update on Flood and Coastal Erosion Risk Management R&D Programme

Reservoir Safety Research and Development News.

The EA have published a brief update on current and planned research projects on reservoir safety by the Joint Defra / Environment Agency Flood and Coastal Erosion Risk Management (FCERM) R&D Programme.

Update available here or via website here.

Update Synopsis below.

Current research projects:

  • Guidance on reservoir conduits (including tunnels, culverts and pipes) - This project is developing guidance for reservoir owners and operators on the inspection, monitoring, investigation, maintenance and repair of reservoir conduits.
  • Investigating the structural safety of cracked concrete dams - The assessment of cracks in dams needs to consider the specifics of the design and construction of each dam and its environment. No two dams are the same, so no simple general rules can be defined.
  • Reservoir Safety Research Strategy - The Reservoir Safety Research Strategy published in 2008 is out-of-date and needs to be refreshed to reflect current priorities.
  • Guide to Drawdown Capacity for Reservoir Safety and Emergency Planning - The Environment Agency is currently working on a project looking at the optimum hydraulic capacity of low-level outlets for reservoirs.
  • Design, Operation & Adaptation of Reservoirs for Flood Storage - The Environment Agency is developing new guidance on reservoirs for flood storage, under its project "Design, Operation and Adaptation of Reservoirs for Flood Storage".

Planned Research

  • Performance of grass and soil in resisting erosion - One of the ways in which an embankment dam or flood embankment can fail is through failure of the grass cover and erosion of the embankment soil, whether via overflowing, overtopping or internal erosion. The rate of erosion - and hence the speed of failure and nature of any flood hydrograph generated by a release of stored water - depends on the performance of the grass cover and the soil erodibility.
  • Dambreak analysis - Understanding and predicting the process by which reservoirs may fail catastrophically is fundamental to how we manage the risk involved.   

Best Practice For Sediment Management for Reservoirs and River Impoundments

A collaborative, UKWIR project, has just started that will be of great interest to reservoir owners, operators and Panel Engineers.

Dams form a barrier to sediment continuity and under the Water Framework Directive reservoirs are considered as "heavily modified water bodies".

The project is being funded and managed by UK Water Industry Research Ltd. (UKWIR).

A project scoping meeting was held in London on 9th September and was attended by representatives from most English, Welsh and Scottish water companies and regulators.  The project plans to include Northern Ireland representatives and outcomes will be applicable well beyond the Water Industry.

As the sole reservoir engineer present at the scoping meeting, I made clear our concerns over the need to be able to routinely operate scour valves.  There was consensus around the room that this was a national problem both from a consenting and operational perspective and I am encouraged to report that it will be addressed through the project as well.

The forum included several case studies. A lot of good work has already been achieved on sediment management and clearance particularly by United Utilities. During his presentation, Matt Buckley (UU), did stress that up to 5 years communication, consultation and negotiations had preceded some UU de-silting schemes.

Understandably siltation problems differ between upland and lowland catchments and these will both be addressed through the project.

I plan to provide a further update once the project scope and programme are fully defined.

In the interim if you wish to engage further with the project please contact Neil Whiter the UKWIR Project Manager at: neilwhiter@hotmail.com.

Scottish Reservoirs Charging Scheme 2015 to 2018

As previously communicated, SEPA published a consultation on a proposed new charging scheme under the Reservoirs (Scotland) Act 2011.

This consultation ran from 15 May until 10 July 2015. SEPA have now published an analysis report of the consultation responses and have written individually to all those who responded. Both the analysis report and summary letter of conclusions and planned actions are published on the SEPA website here or they can also be accessed via the SEPA 'Citizen Space' portal here.

The Reservoirs Charging scheme 2015-2018 has now been published on the SEPA website and is available here.


Small enterprise, great inspiration: Dove Stone Hydropower

This is the story of a small-scale community enterprise tucked away in the Peak District - but one that shows what can be achieved by working together, and how we can take little steps to reduce our reliance on fossil fuels and combat climate change.

Dove Stone Reservoir sits in the parish of Saddleworth, on the edge of the Peak District national park. The team at Saddleworth Community Hydro has invested in retrofitting an existing 30m high head dam at the reservoir site. The £0.5 million scheme now generates 46kW of hydro-electricity continuously, distributed via the National Grid.

For further details visit the blog article here.

CIRIA Guide Launch - Effective asset management of dam & reservoir conduits

On Thursday 10th September 2015 (14:30 to 17:15) a dissemination event will be held in London (venue to be confirmed).

The event will feature an overview of the guide from the Research Team as well as presentations on reservoirs highlighted by case studies in the guide.

Further details on the event can be found here, or on the CIRIA website: www.ciria.org


Scottish Reservoirs Charging Scheme Consultation - Reservoir Managers' Views Required

The Scottish Environment Protection Agency (SEPA) has launched a consultation to seek Reservoir Managers' views on the proposed new charging scheme for reservoir safety which is planned to be introduced on 1 October 2015.

SEPA is required to fully recover the direct regulatory and administrative costs of carrying out its duties under the Reservoirs (Scotland) 2011 Act and it is proposed that these will be recovered from fees and charges, in accordance with the 2011 Act and the Reservoirs (Scotland) Regulations 2015.

The consultation, which is a statutory obligation under the 2011 Act, seeks to gain feedback from reservoir operators on a range of charges including the proposed level of registration fee (out with the initial 6 month free registration period), annual subsistence costs and other charges.

The consultation will run until Friday 10 July 2015.

For more information about the consultation and to submit your response visit SEPA's website.

Procrastination Over Legislative Change

Following the extreme flooding in 2007,  Sir Michael Pitt was appointed by the government to consider how to improve the country's resilience.

He took evidence from many of those affected and industry experts,  including leading panel engineers.  He recognised the need to regulate the Small Raised Reservoirs (SRRs) that constitute a risk to those living and working downstream in the inundation shadow cast by the dam.

For reservoirs,  the Flood and Water Management Act 2010 enshrines the outcome of this process,  but a key component of this legislative change has stalled.

Since the Act was passed Defra has delayed the introduction of this part of the Act seeking "further evidence".  Both the EA and BDS have provided this.  We have written and met with Defra to urge them to progress with these logical changes.

It is with some considerable frustration that I have read the following announcement from Defra which I believe to be politically driven.  We will be unrelenting in our drive to improve the resilience of these structures by urging Defra to complete the logical process initiated by the independent lead they appointed,  Sir Michael Pitt.

Ian Hope Chair of BDS


"Dear all,
We would like to draw your attention to a briefing note that has been published today,  announcing a recent Ministerial decision not to extend reservoir safety regulations to cover smaller reservoirs at the present time.  The note is aimed at reservoir owners,  engineers and other parties who have an interest in reservoir safety policy in England.

Briefing Note from Defra available here

As explained in the briefing note,  Defra intends to work with the engineering community and other interested parties to inform a future decision on whether or not to regulate smaller reservoirs.  To this end, we intend to hold a meeting after the election to review the gaps in the existing evidence base and how best to address them.  We will invite representatives of interested stakeholder groups,  including the engineering,  farming and reservoir owning communities.

Reservoir Safety in Wales - Welsh Government Consultation

The Welsh Government's consultation on the process for bringing into force the amendments to the Reservoirs Act 1975 has now started and will end on 13th August 2014.

This consultation (document available here) seeks views on how to bring Schedule 4 to the Flood and Water Management Act in Wales into force.  This makes amendments to the Reservoirs Act 1975.  It is proposed that the whole of Schedule 4 to the Flood and Water Management Act 2010 comes into force in one go in Wales.  This means that the 1975 Act, as amended by the 2010 Act will apply to all large raised reservoirs with a capacity of over 10,000 cubic metres immediately.  This is about 4 Olympic sized swimming pools.

Responsibility for the enforcement of reservoir safety in Wales rests with Natural Resources Wales (NRW) and they will be responsible for identifying the reservoirs that are at risk.  High risk reservoirs are those where human life would be in danger should there be an uncontrolled release of water.

Comments on these proposals are welcomed.  All responses, including alternative suggestions to the preferred option, will be considered.

For further details and to respond please visit the Welsh Government website here

The consultation will end on 13 August 2014.

Dale Dyke Memorial Plaque Unveiled

On Wednesday 12th March Ian Hope, Chair of the British Dam Society, unveiled an evocative sculpture with annotated plaque to commemorate the 150th anniversary of the Dale Dyke disaster. This dam failure was the biggest disaster of its kind in our history and led to the tragic loss of at least 250 lives.

Memorial Plaque Picture 

In setting the scene Ian placed the early Victorian reservoir building programme into context with the rapid industrial expansion and dire public health needs of the day. Sheffield itself had suffered a number of well documented cholera outbreaks reinforcing the demand for safe drinking water and proper sanitation. The Dale Dyke reservoir was constructed by the Sheffield Waterworks Company following an 1853 Act of Parliament.  In stark contrast to today the Company was not regulated in this activity and was itself able to design, supervise construction and potentially operate the reservoir without independent oversight.

Immediately on completion of construction, the "300 yard long, 85 feet high" dam failed on first filling, exposing inherent weaknesses. The dam was unable to withstand the forces of the full reservoir which were further compounded by a storm event.

There is considerable conjecture as to the cause. As engineers our forensic instincts will remain frustrated! We do know that there were a number of signs we would attribute to degradation of the core by internal erosion - a "whirlpool upstream" and "cracking of the downstream face".  The dam failed during the night when appraisal under candle light would have been unlikely to shed light on the true failure mechanism.

The history of the disaster and post-event hearings brought vested interests and human behaviour into play. The scene was set for a tense and intriguing drama. Clearly Sheffield Waterworks Company was protective of its position and commendably did stand by its employees, principally the Chief Engineer, John Gunsen.  Arguably, had the coroner been less zealous with his corrosive, opinionated, directive approach perhaps the real causes would have been laid open for analysis.

Whilst there remains scant evidence as to the true cause of the failure, we are led to question whether the pressurised pipes through the body of the dam contributed to the failure. We do know that their presence would have created an inherent threat and later designs were to avoid this feature.

Certainly Hawksley, responsible for later dam construction, adopted a far more conservative approach to the construction of neighbouring structures. He undoubtedly had a greater insight as to the cause of failure, being responsible for the demolition of the remaining Dale Dyke dam structure and able to examine key features such as the integral pipework.  He steadfastedly protected the interests of his clients and did not publically admit that the Dale Dyke dam had any defects.These days beyond the internet more information can be found in Geoffrey Binnie's book "Early dam builders in Britain" and geotechnical analysis by the late Peter Vaughan. Dr Andy Hughes, BDS Vice Chair, is conducting a series of talks on the subject (please see BDS website meetings page for further information).  

As an industry we have learnt a great deal from this and other similar tragic events in Victorian times. Our confidence in the significantly increased safety of our dams today comes from the continued vigilance employed by owners and the supervision by properly trained and qualified engineers who form the membership of the British Dam Society. The Reservoirs Act 1975 provides further structured safeguards ensuring the independence of crucial engineering roles which are also detached from direct employment of the owner. Ian Hope Chair British Dam Society.

Environment Agency - Update to reservoir flood maps

The Environment Agency are currently making changes to reservoir flood maps. The following statement has been issued by them regarding the changes that will be taking place.

'The Flood Risk Regulations require the Environment Agency to produce and publish reservoir flood maps, including information on the depth and velocity of flooding that would result from reservoir failure. These maps will be available on our website by the end of March.

We have prepared a briefing note for reservoir owners to tell them what is happening with the Risk of Flooding from Reservoirs map and how they will be used by us and partners.   The Reservoir Flood Maps were produced in 2008/09.  Large raised reservoirs built or completed since that date may not yet have been mapped.   Please find the briefing note attached here.'
