the Berasit Hebrew Dictionary

נהל

'nehel' generally means “inheritance”.

However, nearly a third of the instances of 'nehel' seem to refer to a geographical feature, usually a canyon or a creek. In many of these cases, the word appears to be part of a name of a specific location, so it is possible that the inheritance meaning remains intact in the naming of a geographical feature that belongs to a particular familial inheritance, such as “Schitt's Creek”.
