Well Data Fields

Well data fields can be edited on the Well Grid Viewof the Nodes Grid or the Well Property Sheet.

The following table describes all the Well specific data needed to define a Well.

Further information, including units details, about all the Network Object fields stored in the Master Database can be found in the data fields topics listed in the Network Data Fields topic.

Fields that are common to the majority of objects can be found in the Common Data Fields topic.

The pages on the Property Sheet are listed below. When the network object has Control Data additional pages may be displayed on the property sheet. These pages are marked as follows:

- additional page displayed when Control Data is open

  1. Node Definition Page

  2. User Page - see Common Data Fields topic for details of user fields

  3. Hyperlinks Page - see Common Data Fields topic for details of hyperlinks fields

  4. Notes Page - see Common Data Fields topic for details of notes fields

  5. Well Control Page

  6. Node Control Page

  7. Water Quality Profile Page

  8. Water Quality Turbidity Profile Page
  9. Transient - Pressure Page - fields only enabled when InfoWorks TS (Transient System) licence is present

  10. Control Notes Page

The Grid column tells you if the data item is available for editing in the grid view.

Initial Concentration

The initial concentration of the substance being tested at the start of the simulation. Only one substance can be tested at a time.

These nodes are inputs to the system. The Initial Concentration represents a continuous input concentration over the period of the simulation

If you have defined a time dependent concentration for a node, the time dependent concentration overrides this value between it's start and end times.
