Service
Hydrology and water resources
We quantify rainfall, runoff, floods and droughts to support infrastructure design, water planning and flood risk management.
What we do
Flood hydrology
Design storms, rainfall–runoff modelling and design floods for the return periods your project requires.
Flood hazard and risk mapping
Hazard and risk maps in line with the EU Floods Directive.
Water resources and drought
Water balances, water availability and future demand scenarios.
Urban drainage
Drainage network assessment and sustainable drainage systems (SuDS).
Hydrological data analysis
Quality control of gauging records, gap filling, and trend and change detection.
Climate change and hydrology
Impacts of future climate on floods, droughts and water availability.
Questions we help you answer
What peak flow should this bridge or culvert be designed for?
Which properties are at risk in a 1-in-500-year flood?
Will this reservoir meet demand under a future climate?
How effective will these drainage measures be?
