文摘
- •
Long profiles of tributaries to the Tagus and Zêzere rivers (Portugal) were analyzed.
- •
Tributaries flow across fault bounded blocks with different bedrock lithologies.
- •
A knickpoint/zone separates graded upstream and downstream rejuvenated reaches.
- •
Profile shape and quantification reveals upstream incision wave propagation.
- •
Incision is linked to rock strength and local-regional uplift variability.
