You’llbe joining ourWater and Climate Sciencegroup. UKCEH hosts the largest community of hydrological research scientists in the UK and is the national focal point for hydrological data and analysis. We continue to build on an internationally recognised portfolio of experimental catchments and long‑term observational networks developed over more than 50 years.
Within this environment,you’llbe working alongside thecoreFDRIteammade up ofmore than30 talented and collaborative individualswhotogetherprovidea wide range ofscientific, technical and project managementexpertise.
You will have a research background in field hydrology or geomorphology, and a deep interest in understanding the science of floods and droughts. A good understanding of hydrological data analysis and modelling would be valuable, and you will be experienced in explaining complex ideas to non-specialist audiences. We welcome applications from people working either in research or as hydrological practitioners.
Your main responsibilities will include:
1. Building a body of work that is a recognizable contribution to the advancement of flood and/or drought science to developa track recordof high impact work
2. Leading science and motivating staff across the Floods and Droughts Research Infrastructure project and building strong links to a wide range of projects within and beyond UKCEH
3. Supporting the development of technical assistantsandother hydrologists
4. Leading and managing a diverse portfolio of research projects
5. Leading or contributing key elements of substantial proposals each year andin future yearsattracting funding to enable the advancement of flood and drought science
6. Engaging,maintaininggood workingrelationshipsand influencing stakeholders and stakeholder networks
7. Possess a clear and strategic view of UKCEH science in relation to key national and international priorities
8. Becomingknown beyond UKCEH and collaborating externally,representingUKCEH values and science (e.g. on editorial boards or serving on external committees or panels)
The£38m Floods & Droughts Research Infrastructure () project is building a world-leading hydrological observatory in the UK. We are already advanced with scope,planningand implementation. You will join our implementation team to take a scientific lead in making sure the new FDRI Observatory provides the data and insights that will transform flood and drought research for the 21st century. You will work closely with our external Catchment Champion teams and the wider hydrological community.
New instruments are being installed in 3 catchments (the Chess, the Upper Severn, and the Tweed). The next stage (and the focus of your role in 2026) is to add to thisinitialdesign so that the FDRI catchments can be used to tackle the most pressing scientific questions on flood and drought processes in the UK. In 2027, when data starts to flow, your scientific knowledge will help us to make sure that the instrumentation is working correctly, and you willinitiatepilot studies to help us show the value of the new instrumentation in addressing important hydrological questions. As we approach the operational phase (from 2028 onwards), you will develop a portfolio of research (probably withexternal partners) that uses some aspects of the FDRI infrastructure. You will also be encouraged to develop your own portfolio of field hydrology projects that tackle the questions of flood or drought processes in other locations or from other perspectives. You will publish papers on your work and act as an ambassador for FDRI with the science and practitioner community and beyond.
For the role of Principal Hydrologist,we’relooking for somebody who has:
