DESCRIPTION:Debris flows are high speed flowing mixtures of soil\, rock an
 d water that travel down channelized slopes in surges at typical speeds be
 tween 5 and 25m/s. They may last from several seconds to several hours and
  may flow for kilometers from their source area. In susceptible mountainou
 s areas they pose a major threat to lifelines\, property and lives. The me
 chanics behind the behavior of debris flows are poorly understood. Small-s
 cale laboratory flume tests can help us to understand aspects of their beh
 avior such as their high mobility and tendency to entrain and deposit mate
 rial. This seminar discusses some of the results from some recent studies 
 using a small laboratory flume.\n
