Natural Systems 

The Environment

The challenges of modelling environmental systems include:  

  • a frequent need to consider entirety i.e. the total system
  • many component processes:
    • physical, chemical, biological
    • hydrogeological, geological
    • ecological, climatic, energetic 
    • social, economic and political
  • a wide potential choice of models for the single process domain
  • many models which provide detailed answers to one aspect
  • a common need for expert practitioners
  • wide scope of problem domain
  • short project timescale
  • limited scope for custom development
