Senior Water Scientist & Hydrologist — River & Flood Risk Leader in London

Are you ready to help us shape the future of the water industry? Join our dynamic and multidisciplinary Water Environment team as a Senior Water Scientist or Hydrologist! At AECOM, we’re at the forefront of innovation, delivering an exceptional portfolio of water programmes and projects through long‑term partnerships with key clients.

A selection of our current and recent projects includes:

• Developing catchment‑wide river restoration plans for water companies.
• Delivering hydrological reviews and water balance studies to determine supply sources and keep canals full even when top‑up supplies fail.
• Designing, modelling and installing Natural Flood Management measures.
• Developing modelling approaches and running them to inform management decisions such as water‑level dependent designated sites.
• Improving water companies’ Environmental Improvement Programme (WINEP).
• Designing and delivering fish passes and river restoration schemes.
• Deriving strategies to deliver catchment water quantity and quality improvements driven by WFD and Local Nature Recovery requirements.

The majority of our work is in the fluvial environment, although a significant portion also focuses on estuaries, lakes and the marine environment.

What your new role will entail:

• Support the preparation of high‑quality and commercially astute bids and tenders for water science services, typically for Water Companies and Government bodies such as the Environment Agency.
• Co‑ordinate multidisciplinary teams including water scientists, hydrogeologists, hydromorphologists, aquatic ecologists and flood‑risk specialists, ensuring necessary resources, budgets and controls are in place to meet both programme and budget requirements.
• Identify the need for, plan and implement complex monitoring and field work as may be required (e.g., water‑quality monitoring, flow gauging, hydromorphological surveys, PWS investigations).
• Support delivery of high‑quality water science / hydrology consultancy and advisory services to both internal and external clients, including through our check and review processes.
• Use varied tools to deliver outcomes (software, models, etc.) and review data empirically (e.g., review flow data series and spot gauging to understand low and typical flow hydrology).
• Support development of technically robust and pragmatic solutions to complex water science / hydrological issues.
• Have insight into how hydrological changes influence water quality, geomorphology and hydro‑ecology (e.g., wetted widths and velocities and their effects on fish passage).

Being part of the team:

As an experienced water scientist or hydrologist, you’ll provide support to colleagues and liaise closely with internal and external clients. All members of the Water Environment team take an active role in client contact and commercial aspects of our projects. Health, safety and environmental considerations underpin all of our work.

Qualifications:

• Have a degree (or equivalent) in a relevant subject such as geography, physical sciences, chemistry, maths, engineering etc.
• Experienced in hydrology (low flows and flood risk), hydromorphology, water quality and/or hydro‑ecology with a strong understanding of aquatic systems.
• Proficiency in the application of hydrological software and environmental modelling (hydrological, hydraulic, water quality, water resources).
• Proficiency in GIS software.
• Report‑writing skills and ability to clearly present complex technical information visually and orally to a wide audience.
• Experienced in technical project delivery (from bid preparation, drafting technical proposals to project management).

We celebrate diversity, including neurodiversity, and welcome applications from all backgrounds and abilities. AECOM values every unique contribution and perspective. All your information will be kept confidential according to EEO guidelines.
