Mass Wasting Web Activities

Investigation 1. Angle of Repose
 

• "Would the angle of repose of the same material be different on Mars than on Earth?" - NASA 

An interesting site, which in addition to answering this question, also provides a good review behind the physics of the angle of repose of a material.
http://quest.arc.nasa.gov/mars/ask/soil/Difference_in_angle_of_repose_for_Earth_and_Mars_soils_.txt)
• "The Angle of Repose" - University of Maryland, Geology Lecture Notes 

Slide illustrating the angles of repose for different materials, including moist and dry sand, and sands of various grain sizes.

Investigation 2. Mass Movement
 

• "Debris-Flow Hazards in the United States" - USGS Fact Sheet 176-97 

Site examines different types of debris flows,  where they are likely to occur, and steps to takes to minimize the damages associated with debris flows.

• ""Real-Time" Monitoring of an Active Landslide Above Highway 50, California" - USGS Cascades Volcano Observatory 

Site contains data related to the monitoring of an active landslide between Placerville and South Lake Tahoe, California.
http://vulcan.wr.usgs.gov/Projects/CalifLandslide/framework.html)
• "Landslide monitoring, Woodway, Washington" - USGS  

Site devoted to the study and monitoring of a landslide in western Washington.  Includes a summary of the data collected, including rainfall, pore pressure, and movement data.
http://landslides.usgs.gov/woodway/)
• "Landslide Recognition and Safety Guidelines" - USGS 

Comprehensive site reviews what makes an area susceptible to landsliding and what do to if you are in a high-risk area, as well as providing links to finding out more about landslides.
http://walrus.wr.usgs.gov/elnino/landslide-guidelines.html#Information)
• "Landslide Images" - USGS 

A compilation of landslide images, including a color map of the United States illustrating landslide distribution and several photographs of damage caused by landslides.
