River infrastructure

River infrastructure includes both in-channel structures and flood defences to protect adjacent land. HR Wallingford has a long history of understanding and providing solutions for optimum river infrastructure management We help asset managers target their limited resources for river maintenance to obtain the greatest benefit in terms of risk reduction.

River morphology

River morphology must be considered when assessing the impacts of intervention such as the management or construction of new infrastructure. Changes in the performance of rivers must be assessed and considered in the planning of maintenance options. River sediments can be deposited increasing flood risk, bed levels may erode undermining structures, or river banks can move affecting nearby constructions. To address sediment issues we:Environment Agency water and environment framework

Reservoir sedimentation and operation

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.

Inspection and condition performance assessment of physical assets

Our performance assessments incorporate information gathered from inspection and monitoring into models of both external and internal behaviour of structures. These models make use of empirical and artificial intelligence approaches as well as those based on an understanding of physical processes. Advanced tools assess the reliability (fragility) of infrastructure elements and systems and link these into consequence modelling (e.g. related to flooding extents). We apply these techniques to a wide range of situations and end uses, from regional/national strategic studies to development of local detailed solutions.

River maintenance

HR Wallingford has developed bespoke software that enables clients to evaluate risks and benefits of maintenance activities to both channel condition and defence state. We have also been involved in the assessment of the impacts of river maintenance and the development of best practice guidelines for river maintenance.
