The ubiquitous Connie Woodhouse (one of the stars of The Tree Rings’ Tale) has been working with a team using tree rings to reconstruct the flow of the Indus River:

Dr. Woodhouse did the reconstruction of the water flow level in River Colorado in the US. She is working on a similar project for River Indus by looking at tree rings.

Speaking to Dawn.com, Dr Moinuddin Ahmed said that tree rings are not only used to assess the age of a tree, but also a powerful tool for water flow modeling, forest ecology, archaeology, drought, rainfall, glaciology and climate change. Wood chips from archaeological sites can also be used for dating and other purposes. Thus tree rings provide amazing other details rather than just counting their age. Juniper and Pine trees are often used in dendrochronology.
