Groundwater Modelling at H2Ogeo

There are many applications of groundwater modelling in the environmental sector and a groundwater model provides you with a visual and numerical (Qualitative/Quantitative) tool for testing the potential impacts of different scenarios on the groundwater regime.

There are many types of models available and the correct selection depends on the scope of the project and the potential impacts to be tested.

H2Ogeo provides groundwater modelling solutions to cover a range of scenarios including groundwater flow and groundwater fate and transport, these are discussed in a little more detail below. For more information about H2Ogeo’s modelling capabilities please get in touch via the website or email: info@h2ogeo.co.uk

Groundwater Flow Modelling

A flow model can be used to assess complex interactions between groundwater and the built environment testing the potential impacts of scenarios such as:

  • Changes in runoff and infiltration in a catchment;
  • Surface and groundwater interactions;
  • Groundwater flooding;
  • Diversion of groundwater flow; and/or
  • Introduction of a groundwater pumping abstraction (remediation system for example).

Typical Flow Modelling Applications – understanding the effects of development on a catchment – dewatering design and optimisation – abstraction licensing – heat flow mapping – deep and shallow groundwater interactions – catchment boundary mapping

The flow model is built using a conceptual model that enables attributes to be assigned whilst allowing for changes as the model advances. Attributes include geology and input parameters such as hydraulic conductivity, hydraulic boundary conditions and recharge conditions.

Flow modelling is applied to a range of industries and processes and can be particularly useful when assessing dewatering design, restoration features, the built environment and catchment dynamics.

Fate and Transport Modelling

F&T modelling looks at the movement of potential contaminants in the sub surface and how they interact and break down through natural attenuation. Model outputs can provide the Client with probabilistic terms to assess the likelihood of impacts arising at a known distance away from a polluted area.

They are very useful when designing the success criteria for a programme of remedial works and form an essential part of any risk assessment.

Typical F&T Modelling Applications – human health and environmental risk assessment – land contamination assessments – non intrusive contaminant plume characterisation and mapping – remediation design – validation testing and reporting

Again, like groundwater flow models, fate and transport models are built based on the assumptions gained from a conceptual model. The rigour of this conceptual model is key to generating successful and real-world representative outcomes.
