Activities

Activities may be of different kind : land-uses, services and infrastructures.

Land-uses and Servcies are allways characterized by :
  • total water need
  • total water return
  • cost (investment or maintenance)
  • production
They may be characterized by :
  • clean water need (sensitivity to pollution)
  • clean water return (amount of pollution generated)
  • part of cost in different resources
  • part of production in different resources
The only difference between land-uses and services is that services do not have spatial extension : they do not occupy 1 LPC.

Infrastructures modify water inputs or outputs on a sector or a LPC. They have a cost.
