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