artificial 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 is implemented as a client server system. Groundwater models are located at a central server while Operator Client-applications are distributed to the area staff offices. |
