Groundwater Modelling

Numerical groundwater models provide a powerful quantitative tool to aid the optimisation and management of water resources in an economic, sustainable and environmentally responsible manner.


Groundwater models can be applied to a wide range of problems to optimise water resource management and planning.  They aid water companies, regulators and other abstractors with:

  • Licence application/revision
  • Resource optimisation
  • Conjunctive use schemes
  • Climate change assessment
  • Drought planning
  • Low flows assessments
  • Source feasibility
  • Environment impact assessments for infrastructure development
  • Contaminant transport assessment/saline intrusion
  • Catchment management


We have one of the largest and most technically capable quantitative hydrogeological teams in the UK, with a strong international profile, particularly in the Middle East. We consistently deliver technically robust groundwater models that are used to provide practical answers to the important water resource questions faced by our clients.


Over the past 15 years, we have supported the Environment Agency’s  national programme of regional groundwater model development covering all of England’s major aquifer systems. These models are now available under licence for direct or indirect use (e.g. creation of sub-regional models to address local/site scale issues) by consultants on behalf of water companies. We have built a number of these groundwater models, giving us unparalleled knowledge and experience in their application. These include the:

  • London Basin aquifer
  • Lower Mersey Basin and Merseyside Permo-Triassic Sandstone aquifer
  • East Cheshire Permo-Triassic Sandstone aquifer
  • Birmingham Sherwood Sandstone aquifer
  • Bromsgrove Sherwood Sandstone aquifer
  • Lichfield Permo-Triassic Sandstone aquifer
  • Shropshire Permo-Triassic Sandstone aquifer
  • Cotswolds Limestone aquifer
  • East Yorkshire Chalk aquifer
  • Newent Permo-Triassic Sandstone aquifer


We have also undertaken updates and refinements to the East Midlands-Yorkshire, West Midlands Worfe (Permo-Triassic Sandstone), South West Chilterns (Chalk) and Vale of St Albans (Chalk) groundwater models.


Our modelling team has applied existing groundwater models under licence from the Environment Agency for resource optimisation purposes, low flows assessment and climate change assessment. In addition, we have developed numerical groundwater and contaminant transport models specifically for water companies. Such projects include the assessment of the impact of the Upper Thames Major Resource development on the groundwater flow dynamics and baseline hydrochemistry of a limestone aquifer, and a finite element model to assess the relationship between abstraction and saline intrusion along the south coast of England.


Our groundwater modelling capabilities have also been used internationally, notably in Oman and Qatar.  We have built groundwater models specifically tailored to problems relating to the pressure on aquifers, brought on by rapid development, population growth and industrialisation.
