Are you passionate about using the latest hydrological science to deliver outcomes across the flood-sector?

We're looking for a hydrologist to join one of our Evidence Services operational teams. This is an exciting opportunity to play a key role in the delivery of critical operational services, helping ensure the effective, practical application of hydrology.

You’ll support the team to undertake and review hydrological flood-risk modelling across the land-use planning and FCRM capital investment programmes. Working closely with colleagues across Evidence Services, you’ll help keep our wider flood-risk modelling work moving, providing cornerstone hydrological expertise that underpin the modelling chain.

Working alongside technical specialists, you will undertake hydrological analysis, contribute to national improvement projects and provide evidence that supports better decisions during both business-as-usual and flood incidents.

The Environment Agency is fully committed to inclusivity and equal opportunities, offering flexible work arrangements for all our vacancies. Join us in a diverse environment where every voice is heard and valued, and where your contribution can make a real difference to colleagues, customers and the environment.

Data and Information Management

As a hydrologist you will call upon an array of datasets and methods to draw conclusions.

Describe a time when you used environmental, scientific or engineering data to investigate a problem or answer a question. What was the outcome of your analysis?

Takes Decisions and Solves Problems

In your work you will need to balance the desire to have a complete picture against the operational reality of meeting deadlines.

Describe a situation where you were asked to solve a technical problem with incomplete information. How did you make a decision without all the facts?

Works in Teams

Hydrology is the technical starting point for flood-risk modelling, but it is only one component of a much bigger and longer chain.

Describe a time when you worked with people from different teams, disciplines or backgrounds to achieve a collective outcome. What was your role and what did you do to ensure the overarching piece of work was a success?

Focuses on Customers and Partners
