Stream order
v19 v20 19 19 Because the orders are additive, the numbers from the Shreve method are sometimes referred to as magnitudes instead of orders. The magnitude of a link in the Shreve method is the number of upstream links.[[BR]] 20 20 21 Shreve, R. , Statistical Law of Stream Numbers, J. Geol., 74, (1966), 17-37.
