you just have to define the members of the relationship correctly:
if the boundary is the middle of the river and moves if the river moves, 
then you have to put the end of this river in the relation.
if the river passes at this place without following the future 
evolutions of the river, then one should not include the river in the 
relation but make a new object.
a description tag would help a lot to keep this information but it is in 
my opinion a titanic work to find the definition of many borders
