An antecedent stream maintains its course by downcutting at the same rate as tectonic uplift. As the stream existed prior to uplift, it is able to maintain its path and continue downcutting despite the change in elevation. Meandering streams are not necessarily maintaining their course in relation to uplift, but rather the curves of the meanders gradually shift over time. Anabranching rivers describe a river that has multiple channels or branches that divide and rejoin, while rejuvenated rivers have experienced a sudden uplift and change in base level, causing them to downcut rapidly and create a new channel.
