Physical and numerical modelling for dams and reservoirs
Our staff have a wide range of experience in the design and application of differing types of risk assessments for reservoirs, and have driven the development of the latest national guidance on reservoir risk assessment for the UK Government. We can provide:
Every year, sedimentation causes an estimated one per cent reduction in the total capacity of all reservoirs worldwide. Sediments also block intakes in reservoirs and damage tunnels and turbines. HR Wallingford has undertaken research and consultancy studies in reservoir sedimentation over many years. We have expertise in sediment measurement techniques, reservoir surveys and their analysis, sediment transport processes in river basins and the application of numerical models in reservoir sedimentation studies. Our numerical models can predict future reservoir storage and test operational changes, and we offer expert advice, desk studies, field monitoring, surveying and its analysis, numerical modelling and training.
Although they are normally low probability events, dam breaks or embankment (levee/dike) breaches can have enormous cost and loss of life consequences. Responsible dam owners seek to assess and manage this significant risk (probability and consequence) in order to protect those downstream and to manage their liability. We can provide the following services:
Our state-of-the-art physical modelling facilities are used to optimise structure designs at an early stage, preventing costly operational issues later. Our complimentary numerical modelling systems ensure a solution for any complex hydraulic design problem.
Our staff have many years experience in the inspection and condition assessment of dams, both in the UK and internationally. We are able to provide the following services:
Recent research advances allow us to offer reservoir owners exciting new possibilities for cost-effective monitoring of embankment dams. Services include design and specification of bespoke long-term monitoring systems embedded in embankment dams, twinned with artificial intelligence (AI) continuous monitoring and a suite of powerful modelling tools for emergency planning and response.
Developed in association with the UK Environment Agency, our ARC-Boat is a radio-controlled surveying boat capable of undertaking fast effective reservoir depth and volume surveys with minimum health and safety risks to site personnel, and at lower cost than traditional manned surveys.
We can help you in all areas concerning the safety of dams and reservoirs: from safety inspections by qualified Panel Engineers, to risk assessments for reservoirs and dams, early warning systems and flood mapping.
