How to correct your Water Overlay data
When working with the Water Overlay, it is desirable to work directly with the source data available. However, there may be aspects of the data which conflict with the way the Water Overlay functions. These situations may require some corrections to have the data properly interpreted by the calculation model.
Depending on the situation, clear instructions to correct the issue may exist. However, due to the inherent complexity which may be involved with various combinations of data, for some situations only advice on how to investigate a potentially erroneous phenomenon can be offered.
Corrections
How to correct multiple constructions on the same location
- Multiple parallel constructions of the same type - Inlet or sewer overflow attached to other constructions - Pump attached to other constructions - Culvert attached to weir - Constructions near each other
How to correct weir, pump, or culvert drawn as point
How to correct a construction in an uninterrupted waterway
How to correct a construction at the edge of the project area
How to correct a culvert connecting two water level areas
Investigations

- Waterways to narrow for grid size - Waterways loaded with insufficient depth - Waterways blocked by constructions
