The calculation type water flow is used to add one or more features of naturally inflowing water through the rock and subtract the water added by human activity (e.g. the water added to the tunnel for injection).
On connected features, the features that are the input of the calculation should be drag and dropped. This included both incoming water (natural) and process water (human activity).
All features that should be included in the calculation need to be included here.
All features that should be included in the calculation need to have a specified water flow direction. This is a type specific property of the source features.
If we have two dams where we measure average flow and one pump where we measure added water / process water we would have two feature with flow direction + and one with -.
The inflowing classification element can be named anything. But is has to be in the first position of the classifications. Added water / process water need to be in the second place.
If we have these three features:
Feature |
Direction |
Value |
Inflow 1 |
In (1) |
3 l/min |
Inflow 2 |
In (1) |
2 l/min |
Added |
PV (2) |
4 l/min |
The result would be 1 l/min for that time block.
