Introducing the NGMS
The NGMS is a scenario analysis tool to assess the impacts of abstractions on the groundwater resources and the surface water flows.
The system contains a set of default scenarios which allow the user to understand the interaction relations between the various components in the system.
To analyse a change in artifical influences (i.e. human interventions), what-if scenarios can be conducted by modifying the input of the default runs. Modifications that are supported so far are changes in abstraction rates or the addition or removal of abstractions.
Based on the scenario definition, the NGMS executes a sequence of data processing steps to preprocess the input to the groundwater model, to run the model and to postprocess the data. The output can be presented in time series graphs, accretion profiles or spatial plots. The system automatically conducts a data comparison between different runs.
The NGMS project
The NGMS project is commissioned by the Environment Agency of England and Wales. The project is implemented by a consortium composed of WL Delft Hydraulics (lead), Tessella Support Services ltd. (IT-services) and Environmental Simulations International (hydrogeological expertise, configuration services). The project is conducted in co-operation with the EA and the UK-GW consultant Entec (configuration services).
