10.6E| Exercise: Why Some Streams Meander but Others Are Straight?

To answer this question, we need to consider if there is a relationship between the gradient of a stream (the "steepness" of the slope over which the stream flows) and its sinuosity (curviness). 

Instructions

After watching and listening, considering the lecture, completing the assigned lecture reading, and familiarizing yourself with stream-related landform features, you should be able to complete this exercise. You have two attempts and no time limit.  

I've prepared a tutorial video (below) that you might find useful. Note that my demonstration uses a paperback version of a lab manual, but you can do the same on your computer screen.

Time Needed

30-60 minutes. 

Learning Objectives

• Students can describe the role weathering, mass wasting, and erosion play in shaping Earth's surface and can provide and/or identify examples of each of these processes
• Students can describe the evolution of landforms and geologic structures in the context of constructive and/or destructive geologic processes
  
• Identify and interpret geologic features from topographic maps
• Identify and describe how landforms are created by stream erosion and deposition
• Compare and contrast the physical characteristics of the three types of stream channels and locate each along a typical stream profile
• Calculate sinuosity and gradient and describe the relationship between the two
