Question

. What is the eventual fate of the Oxbow Bend at Location A(snake river, grand teton national park)?

2. Using the Google Earth™ mapping service, follow the Colorado River to its terminus (the mouth of the river where it empties into a body of water). What is the name of this body of water?

3. Is there a delta at the terminus of the Colorado River? If so, is it high-constructive or high-destructive. If not, why do you think it is absent?

4. Is the landform at Location E high-destructive or high-constructive? How can you tell?

5. Calculate the average discharge of the Mississippi River at New Orleans (in cubic feet per second) given the following parameters: (show your work)

Average velocity: 2.5 miles per hour Average width: 2,000 feet Average depth: 90 feet

Discharge = velocity (ft/sec) x river width (ft) x river depth (ft)

*Remember, you will need to convert miles-per-hour to feet-per-second to obtain the proper units for discharge (ft3/sec). There are 5,280 feet in a mile.

Explanation / Answer

1. At the Oxbow Bend, as time progresses, sediments carried by the river will be deposited at the two mouths of the bend and cutting the bend off the river. Hence it wil become an isolated lake.

2. The Colorado river terminates at the Gulf of California

3. Yes the Colorado river forms a delta. It is a constructive delta as the sediments are brought by the river and deposited in the delta

4. Please give the coordinates of "Location E"

5. Given

Velocity (v)= 2.5 mph= 3.6 feet/ sec (1mph= 1.47 feet/sec)

Width (w) = 2000 feet

Depth (d)= 90 feet

Discharge (D)= v*w*d= 3.6*2000*90= 648000 ft3/sec
