River Systems Activities
Activity 1 
Activity 2 
Activity 3 
Activity 4 
Activity 5 
Students are challenged to use their understanding of river systems to plan a riverside park in or near their community.

Students will: 

Activity 1  --  High-Gradient Streams
To learn more about this topic, visit the following web sites:

1. Characteristics of High-Gradient Streams:


Activity 2  --  Low-Gradient Streams
To learn more about this topic, visit the following web sites:
1. Meandering Streams 2. Streams and the Hydrologic Cycle 3. Hazards: Floods on Low-Gradient Streams

Activity 3  --  Sediments in Streams
To learn more about this topic, visit the following web sites:

1. Size Range of Sediments

  • How fast do sediment grains of different sizes settle?, Society for Sedimentary Geology 

  • Check out this sample lesson plan for a lab about sediment grains settling rate.
    (http://www.beloit.edu/~SEPM/Earth_Works/How_fast_do_sed.html)
    2. Transportation of Sediment by Streams
  • Field Exercise: Stream Flow Dynamics and Sedimentation, Society for Sedimentary Geology 

  • Another lab to try but this one is outside.
    (http://www.beloit.edu/~SEPM/Earth_Works/Stream_Flow.html)
    3. How Streams Reduce the Sizes of Sediment Particles 
  • Streams and Drainage Systems, Tulane University 

  • Read an overview of many of the topics covered in this chapter, including particle size changes downstream (see the "Changes Downstream" section).

    4. Downstream Fining
  • Journal of Sedimentary Research Articles - Abstracts 

  • Here are two abstracts for papers published in Journal of Sedimentary Research.  The links take you to pages that include the necessary information to look up the article.
