| Datum | Datum/offset which is added to the level column in the level/width table to get true level. |
| GeometryCrossSectionLocation | Location of cross section data for weir geometry. If null, the location of the structure in the network is used. |
| GeometryCrossSectionTopoId | TopoID of cross section data for weir geometry. If null or empty, the topo id of the structure in the network is used. |
| GeometryDataFromCrossSections | Flag specifying wether to use geometry data from cross section database. |
| LevelWidths |
Weir geometry defined as levels and corresponding flow widths.
The levels are relative to the Datum. Levels must be increasing. |
| LowestLevel | Get lowest water level |
