SUMMARY:Irina Nikolkina\: Savage-Hutter model for avalanche dynamics in inclined channels\: analytical solutions
DESCRIPTION:The Savage-Hutter model is applied to describe gravity dri
 ven shallow water flows in\ninclined channels of parabolic-like shapes
  modeling avalanches moving in mountain\nvalleys or landslide motions 
 in underwater canyons. The Coulomb (sliding) friction term\nis include
 d in the model. Several analytical solutions describing the nonlinear 
 dynamics of\navalanches are obtained\: the nonlinear deformed (Riemann
 ) wave\, the dam break problem\,\nself-similar solutions and others. S
 ome of them extend the known solution for an\ninclined plate (one-dime
 nsional geometry). The cross-section shape of the inclined\nchannels s
 ignificantly influences the speed of avalanche propagation and charact
 eristic\ntime of dynamical processes. Obtained analytical solutions ca
 n be used to test numerical\nmodels and to give insights into the stru
 cture of avalanche flow and to highlight basic\nmechanisms of avalanch
 e dynamics.
