Senior Hydraulic Modeller

Joining Arup

The successful design, development and maintenance of our water infrastructure requires the integration of many disciplines. Arup's water team has wide-ranging skills spanning advisory and specialist technical services. We apply them on all types of projects, from flood risk management and water resource planning, to dam engineering, treatment works design and river engineering.

The main focus of Arup's Water team in Sheffield is stormwater. We advise our clients on the risk of flooding at strategic (city or region-wide) or site scale. We model the movement of water and the risks associated with flooding, using integrated hydraulic models. We plan and design nature-based solutions to manage stormwater and provide wider benefits in the built and rural environment. This team has enjoyed strong organic growth, but demand for practical and rigorously proven solutions continues to rise.

The Opportunity

We are seeking a experienced person with deep curiosity for the impact that water can have on people's lives; someone who is driven to help us protect others. For this particular role we would expect you to have extensive experience of hydraulic modelling. We predominantly use InfoWorks ICM, but we will consider applicants with backgrounds in other hydraulic modelling software. You might also be digital-savvy and have an interest in using digital tools to solve complex problems or eliminate repetitive tasks. You will have opportunities to help us with other aspects of our stormwater project work, but this role is for someone who enjoys the challenge of creating and refining hydraulic models whilst supporting the development of junior modellers. Your educational background could be as an engineer, a scientist or in a related discipline. We appreciate the value of diversity of education and experience because it allows us to bring new perspectives and alternative solutions.

Reporting to the Water Team Leader in Sheffield, you will contribute to stormwater and fluvial hydraulic modelling projects which will include integrated modelling approaches. You will help us with water quality modelling and building complex 1D-2D hydraulic models. Our clients include the Environment Agency, water companies, local authorities and major infrastructure operators, so expect to work with and create models to solve a variety of different problems. The ideal candidate will have experience in hydraulic modelling, flood risk management and understand the basics of rural and urban hydrology. Working as part of a team you will provide hands-on input to our projects with the use of technical analysis and designing software packages.

Is this role right for you?

As a Senior Hydraulic Modeller at Arup, you will be building and simulating hydraulic models, extracting results and drawing conclusions. You will use GIS software to manipulate results and create informative images and produce technical reports to convey complex concepts. Therefore, practical experience of hydraulic modelling software - ideally InfoWorks ICM or other Autodesk water software products is a key requirement for this role. However, we will consider candidates with strong experience of other urban drainage or river modelling products such as MIKE, FloodModeller, Tuflow, HEC-RAS, etc. You will lead and be responsible for a broad range of UK and international projects at all stages including strategic advice, catchment and city level planning, concept and detailed solutions, and post construction evaluation.

The role involves leading and delivering hydraulic modelling projects, including the development, calibration, and validation of 1D-2D models, ensuring compliance with industry standards and specifications. It requires the use of 1D-2D hydraulic models for risk analysis and the development of solutions that improve water quality and mitigate flood risks, such as surface water and fluvial flood mapping, as well as reducing storm overflows through sustainable drainage systems and natural flood management. The individual is responsible for supporting project delivery by assisting the Project Manager with programme scheduling, budget management, and quality assurance processes within their area of expertise.

We are seeking the following skills and experience:

• Track record of successfully delivering water projects in the UK, including collaboration with private/public sector clients and regulators.
• Qualification in Engineering, Geography, Environmental Science, or a related discipline, chartered or close to chartership with an appropriate professional body.
• Competent in the use of GIS software such as ArcGIS or QGIS to incorporate complex 3D surfaces into hydraulic models and present model results
• Skills in hydrological assessments and producing or contributing towards Flood Risk Assessments and Drainage Impact Assessments
• Ability to Work with 1D-2D integrated catchment models including an appreciation of the opportunities and limitations in these
• A basic working knowledge of AutoCAD Civil 3D and/or other 3D design packages and how these are used to incorporate complex 3D designs into hydraulic models
