1. Identify fluvial landforms from satellite imagery,

2. Understand the difference between meandering and braided streams, and where each is likely to be found

This activity provides you with satellite views of stream and rivers on Earth through the Google Earth application. Firstly, you will find an example of both a meandering and braided river and cut-and-paste the image into their assignment. Then you will use Google Earth Pro to determine the river type, channel width, floodplain, gradient, etc.

Activities
1. Fly to "Harbin" (Heilongjiang, China) just southwest the city is a beautiful series of scroll bars (former point bars that have been abandoned) formed by the meandering river.
1) Moving across the landscape, identify the current main river channels;
2) Give yourself a sense of the rate of geomorphic change in these fluvial landforms. Use the clock function to toggle between the oldest and youngest satellite images. Do you see any evidence of the meander bends moving?
3) Find an oxbow lake, capture a screenshot and paste here.
14) Find a point bar and a cutbank section and post a screenshot below. Identify the difference between the erosional and depositional landform features.
2. Locate Horseshoe Bend (near Page, AZ), which is part of the Colorado River east of the Grand Canyon. (1 point)
1) First, explore this part of the Colorado River in Google Earth and describe the type of river present. Paste a screenshot of the Horseshoe Bend.
2) How is this river similar or different to the portion of the River Channels around Harbin that you observed in Question 1?
3) What process is forming the meanders here? In other words, how on earth do you get a river to meander in bedrock?
