A Lancaster University environmental science graduate has earned national recognition for research that tackles one of the most persistent problems in flood risk management. Alex Waterer received the British Hydrological Society (BHS) Student Award 2026 at the BHS 2026 Symposium in Leeds on 3 September, a prize given to the best final-year undergraduate dissertation in the UK on a hydrological subject.
Alex’s research focused on Grasmere in Cumbria, where flood risk may be considerably greater than short-term observations suggest. By applying a new modelling approach to extend limited river level records, the project revealed flood patterns that conventional monitoring had missed. The findings carry practical weight for engineers designing flood defences and for communities preparing for future storms.
For prospective students weighing whether to study environmental science, the story shows what well-supervised undergraduate research can achieve — and how a dissertation can move beyond an academic exercise to influence national practice.

Why Flood Risk Research in Small and Upland Catchments Matters
Alex described the core problem his dissertation addressed as the “fundamental challenge” in flood risk management: many small and upland catchments have little or no long-term hydrometric data. Without decades of river level and discharge measurements, it becomes extremely difficult to understand how frequently floods occur and how severe they can become.
The Data Gap Challenge in Flood Risk Management
National flood estimation methods rely heavily on gauging stations that record river levels continuously. Large rivers often benefit from monitoring programmes stretching back 40, 50, or more years. Small catchments — the streams and becks that drain fells, moorland, and rural landscapes — rarely receive the same attention. Equipment costs, access difficulties, and competing priorities mean many of these watercourses have records covering only a handful of years.
That gap matters. Design decisions for bridges, culverts, flood walls, and community warning systems depend on estimates of rare but damaging events. When the observational record is short, those estimates rest on shaky ground. A decade of relatively quiet weather can make a location appear safer than it is, while a decade of storms can exaggerate the threat.
How Hindcasting Extended Grasmere’s Flood Record Back to 1981
Alex’s dissertation responded to this challenge with a practical solution. Rather than relying solely on the short record at Grasmere itself, the project used data from a gauging station downstream at Ambleside. Because the two locations share the same river system, conditions recorded at the downstream site carry information about what happened upstream.
Using a new modelling approach, Alex “hindcast” river levels and discharge at Grasmere — reconstructing what the river likely did in the past based on the downstream measurements. The technique extended the flood record at Grasmere from 2020 back to 1981, adding roughly four decades of context that no local gauge had captured.
What the Reconstructed Flood Record Revealed
The extended record delivered a clear warning. Speaking about the findings, Alex said: “The reconstructed record revealed that a reliance on short observational records can be misleading with regards to flood risk.”
In other words, the floods observed during the short modern monitoring period at Grasmere did not represent the full range of behaviour the river can produce. Events that would have appeared unprecedented to a short record were visible in the reconstruction as part of a longer pattern.
Alex continued: “By making better use of related hydrological data, we can reveal previously unseen patterns of flood risk to help in the design flood mitigation works, and support communities to better prepare for likely future floods.”
Three practical implications follow from this approach:
- Better flood mitigation design. Engineers can size defences and drainage systems using flood frequency estimates grounded in decades rather than a few years of data.
- Improved community preparedness. Residents and local authorities gain a more realistic picture of how often significant flooding may occur.
- Transferable methods. Communities near small, ungauged, or briefly gauged watercourses elsewhere can apply similar reconstruction techniques using nearby downstream stations.
“Recognition of the value of my research and its potential contribution to flood risk management nationally is a significant honour,” Alex added.
How an Undergraduate Dissertation Earns National Recognition
The BHS Student Award is not given for routine coursework. It recognises dissertation projects that demonstrate methodological rigour, originality, and genuine relevance to hydrological practice. Alex’s win illustrates several qualities that separate award-winning student research from the ordinary:
- Select a problem with real-world consequences. The data gap in small catchments affects flood defence budgets and public safety. Addressing it gave the project purpose beyond a grade.
- Work closely with an experienced supervisor. Regular guidance helped shape the modelling approach and sharpen the analysis.
- Apply methods rather than simply describe them. The dissertation produced a working reconstruction, not just a literature review.
- Communicate findings clearly. Award panels look for work that practitioners and communities can actually use.

Studying Environmental Science at Lancaster University
Alex completed his degree within the Lancaster Environment Centre, home to the university’s environmental science teaching and research. The centre brings together academics working on water resources, climate, pollution, and land management, giving students direct access to specialists in their fields of interest.
Supervision played a central role in the project’s success. Dr Nick Chappell, Alex’s supervisor in the Lancaster Environment Centre, said: “Alex has been an exemplary student and has a bright future helping others assess and reduce flood risk by applying and deepening his skills developed at Lancaster.”
That relationship illustrates a broader point for prospective students: the quality of dissertation supervision can shape the direction of a career. A supervisor with active research interests in hydrology can open doors to conferences, professional networks, and awards such as the BHS Student Award.

Careers in Hydrology and Flood Risk Management
Award-winning dissertations often mark the start of a career rather than the end of a degree. Hydrology and flood risk management offer varied employment paths for graduates with strong quantitative and environmental skills:
- Flood risk analyst or consultant. Assessing flood hazard for development planning, insurance, and infrastructure design.
- Hydrologist or hydrometrist. Managing gauging networks, analysing river data, and producing forecasts for environmental agencies.
- Water resources specialist. Balancing supply, abstraction, and environmental needs for water companies and regulators.
- Researcher or postgraduate student. Deepening expertise through master’s study or a PhD, often building directly on undergraduate dissertation work.
Demand for these skills continues to grow as climate change alters rainfall patterns and increases the frequency of extreme events. Graduates who can extract reliable insight from imperfect or limited data — exactly the skill Alex’s project demonstrates — are particularly valuable to employers.
Practical Steps for Students Pursuing Hydrology Research
Students inspired by this achievement can take concrete steps to build similar opportunities:
- Choose a topic grounded in a genuine data or knowledge gap. Review existing monitoring records in your region and look for catchments with short or missing records.
- Learn data analysis and modelling tools early. Skills in statistics, programming, and GIS expand the range of dissertation methods available to you.
- Seek supervisors whose research aligns with your interests. Read staff profiles and recent publications before committing to a project.
- Enter professional awards and attend symposia. Bodies such as the British Hydrological Society run prizes and conferences that give student work national visibility.
- Write for practitioners as well as examiners. Clear, applied conclusions increase the chance your work influences real flood risk management.

Frequently Asked Questions About the Award-Winning Flooding Research
What is the British Hydrological Society Student Award?
The BHS Student Award recognises the best final-year undergraduate dissertation in the UK on a hydrological subject. It is presented at the society’s national symposium, held this year in Leeds.
What does hindcasting mean in flood research?
Hindcasting uses downstream or related measurements to reconstruct past conditions at a location that lacks its own long-term records. In this project, data from Ambleside helped estimate river levels and discharge at Grasmere between 1981 and 2020.
Why is flood risk underestimated in small catchments?
Short observational records may not capture rare, extreme events. A few quiet years can make flood frequency appear lower than it truly is, leading to under-designed defences and communities that are less prepared than they should be.
Final Thoughts: Applying Research Skills to Real Flood Challenges
Alex Waterer’s award demonstrates that undergraduate research, when matched to a genuine problem and guided by experienced supervisors, can influence national practice in flood risk management. His reconstructed record for Grasmere gives engineers, planners, and residents a more honest picture of the floods their landscape can produce — and offers a method other communities can adapt.
For students considering environmental science, the message is straightforward: choose meaningful questions, build strong analytical skills, and connect with the supervisors and professional bodies that can amplify your work.
