1 CIVIL INFRASTRUCTURE HYDRAULIC ENGINEERING

2 INTEGRATED, EFFICIENT, SMART Ageing infrastructure networks struggle to keep up with 21 st century demands for water, sanitation & health. The provision of major new civil infrastructures projects to deliver increased capacity and sustainable supply is high on the agenda. In delivering these projects to time, cost and quality, whilst undertaking active risk-mitigation, project managers and owners need to make informed decisions about project design early in the process. The hydraulic design of major water systems, whether for water treatment, sanitisation, power generation cooling or irrigation, is key to the efficient operation of the process. Poor design leads to inefficiencies, through unpredicted turbulence, restricted throughputs, pumping inefficiencies, and erosion. All of these factors can have significant adverse effects on both capital and operating expenditure. The hydraulic design of channels, structures and reservoirs is critical to the success of major civil and mechanical engineering projects in water and fluid related environments. When the British Hydromechanics Research Association was established by the UK Government over 65 years ago, we were set the goal of being experts, providing innovative technologies, design and support across all industries. Today, as an independent engineering consultancy, BHR Group s hydraulic engineering experts have the specialist experience and cutting-edge technology to provide appropriate solutions to your civil infrastructure projects. Our aim remains the same as it was when we were founded: to be the people you trust to provide innovative and reliable solutions.

3 CUSTOMER NEEDS Problems in design, validation and optimisation can result in lengthy project times and costly delays. The importance of engineers experienced in fluid mechanics, hydrodynamics and computational simulation on the profitability and safety of civil infrastructure projects involving fluid transport cannot be overstated. Whether the project involves designing smart water networks, building flood control or water management structures, or installing water, drainage and sewer systems, BHR s hydraulic engineering experts have specialist experience and cutting-edge technology to provide appropriate solutions. BHR Group expertise has played a key role in delivering some of the largest and most complex civil infrastructure projects, including: Tunnels Flood control and water management Water & wastewater treatment plant Water supply / wastewater handling Water, drainage & sewer Dams, water / runoff storage reservoirs Sustainable Drainage Systems By working in collaboration, BHR Group provide the leading edge knowledge and technology you require. By delivering and implementing sustainable solutions, you save time and money and reduce environmental impact the key drivers in any business.

5 FLOW TESTING CAPABILITIES BHR Group s multi-disciplinary teams provide an integrated engineering approach to fluid system design and build, testing and verification, optimisation and scenario-planning. Our scaled physical modelling expertise is complemented by computational modelling and simulation, whilst our experimental work, in-house and on-site testing, and evaluation allows us to validate and calibrate our results. Flow modelling is an indispensable tool in reducing the risks involved in fluid flow projects. BHR uses both scaled physical models and computational fluid dynamics (CFD) to validate the hydraulic design of civil engineering structures in advance of construction. CFD is a powerful tool to describe the hydrodynamics around structures and used in combination with physical models, can deliver an holistic validation programme to aid engineering design. Our CFD model results can influence subsequent physical model tests and our physical model experiences can influence CFD prototypes, ensuring that we capture and adequately describe all the key features of the flow. By combining disciplines, BHR can offer a fully integrated service, ensuring we deliver the best possible advice to our clients.

6 PHYSICAL SCALE MODELLING Other than building a full scale prototype and testing it, the use of a geometric scale model can often be the most reliable way of ensuring proper performance of flow equipment or fluid flow systems. Physical modelling can identify key features of the flow that cannot be captured and adequately described with CFD alone - such as vortex classification, frequency or attachment points. BHR Group s dedicated large scale hydraulics laboratory is able to accommodate large physical models ranging from simple flow structures to large scale constructions with representative topography, geology and geography. Our test facilities are equipped with sophisticated control and measuring systems to study and validate the design of complex hydraulic structures such as dams, water intakes, pumping stations, siphons, vortex shafts, etc. The laboratory also has first-rank experience in modelling sedimentary dynamics in rivers (erosion and sedimentation downstream of civil structures) or torrents (mudslides). BHR has over 60 years experience in physical scale modelling and a comprehensive understanding of the scaling laws and empirical guidelines that are critical to deliver accurate results. Our team has designed and built models for countless industrial and environmental projects including: Hydraulic structures Fish passage systems Nuclear safety systems Pump intakes and wet wells Cooling water intake structures Oil containment and clean up equipment Gas flow ducting and ventilation systems Air pollution control equipment

7 COMPUTATIONAL FLOW DYNAMICS (CFD) CFD enables us to simulate a wide range of physical conditions to analyse flow around civil structures and evaluate how structures will perform. Our specialized areas of expertise include: Pressure and flow analyses to test existing structures or prototypes Simulation of turbulence, flocculation, mixing Simulation of dam spillway and dam breaking Treatment chemical mixing and resiliance and contact times Our expertise encompasses the client value chain. Typical projects include: Virtual tests providing simulations where cost or practicalities of physical testing are prohibitive Design review to evaluate and optimise designs before development proceeds Troubleshooting to diagnose problems and redesign Safe exploration of failure scenarios and quantified consequences Joined-up thinking Numerical and computational modelling used in conjunction with physical scale models provides an effective and validated analysis of the performance of a system, design or adaptation. BHR s ability to offer back-to-back physical modelling and CFD enables us to deliver a comprehensive service to our clients, delivering the best possible analysis from design review through to commissioning. BHR engineers can deliver a full-service solution to clients and expedite project delivery. By effective use of the appropriate tools and techniques at the right time, we can often reduce development and commissioning time for our clients, shortening time to delivery and improving performance and reliability of infrastructure projects, all of which translates into lower project costs and a higher return on investment.
