WaterWare scenarios: Consistency Checker

This operates on the DATA BASE representation of a scenario in conjunction with the editing tools.

The Checker can be run:

• on demand from the main scenario editor summary page;
• automatically before a model is run (not yet implemented)

Things being checked:

1. Network has at least ONE start and end node;
2. Only a START type node is defined as start node/headwater.
3. Connectivity: all nodes defined are connected (used in reaches);
4. Connectivity: each node type has the correct number of reaches:
   • start, end (and recharge): 1
   • diversion, confluence: 3
   • everything else: 2
5. Diversions: one branch is defined as of type: diversion (the other is of type mainstream);
6. Diversion: parameters or time-series are defined depending on strategy selected;
7. Reach length should not exceed 20 km (warning) and must not exceed 40 km (error);
8. Slope: start node in a reach must be above or at the same level as the end node.
9. Reservoirs: parameters or time series defined depending on strategy selected;
10. Reservoirs: feasibility of initial conditions (initial volume must correspond to a level between dead storage and spill/top level).
11. Percentage values SET must be between 0 and 100.
12. TS multipliers: no ZEROS;
13. Reaches: ALL parameters are defined (ENSURE through the proper use of DEFAULTS !!!);
14. Aquifer: initial volume must correspond to a level between aquifer depth and the surface;
15. Meta Data: Description is different from NAME !
