| 23 * There is a modeling problem with the RiverAxis. The initial idea was, that a | |
| 24 * river can have a riveraxis that consist of exact one geometry. Now, it has | |
| 25 * turned out, that a single geometry is not enough for a riveraxis (arm of a | |
| 26 * river, inflows, ...). As workaround, we now expect, that a river can just | |
| 27 * have a single riveraxis. | |
