Question 1
If you wanted to build a structure along a river
especially one that flows through unconsolidated sediments
you should build the structure ________ to maximize its lifetime.
◦ along the cutbank

◦ Any of these is equally safe.
Question 2

◦ sediments accumulate upstream in response to the loss of flow velocity.
◦ sea level changes.
