Inquiring Further

  1. To learn more about sediment clean up after a flood, visit the following web sites:

    Flooding: About Cleaning up Yards and Public Spaces, Rhode Island Department of Health
    Provides suggestions for what to do when a public space is covered with floodwater.

    After the Flood, University of Missouri
    Explains how to clean up flooded areas.

    Flood Safety Checklist, American Red Cross
    Suggestions for dealing with a home that has been flooded.

  2. To learn more about the ways in which types of sediment in a streambed indicate support plans and animals, visit the following web sites:

    Rivers and Streams, EPA
    Describes some of the different types of habitats that form along a streambed, depending on the materials that accumulate on the streambed.

    River Ecosystems, Trinity College
    Diagram that shows different types of streams and the ecosystems that form in these streams.  Explains the different sediment types that influence various stream ecosystems.
