Sorry for cross-posting.
We would like to draw your attention to the following session at the next EGU General Assembly (17–22 April 2016); abstract submission deadline 13th of January 2016.
We welcome the contribution of those of you interested.
NH3.2: Assessing runout and rheology of complex hazardous flow through numerical and experimental models
Rapid, massive geophysical gravitational flows such as lahars, debris
flows and rock avalanches are among the most hazardous phenomena at
mountains and volcanoes. Among all geophysical gravitational flow
phenomena, these are the most lethal and destructive:
they can travel for several kilometres along volcanoes and mountains
slopes and valleys. Their speed usually exceeds 100 km/hr and their
volume is greater than a million cubic metres. The large quantity of
mass in movement can develop a considerable energy,
greater than the one developed by an earthquake of magnitude 6. This
enormous energy developed in a short time has tremendous power of
destruction that can cause irreparable damage, changes in the landscape
and a large number of fatalities, destroying entire
villages and burying thousands of people.
At present time the mechanisms involved in these phenomena are still for
most part unknown. Several theories have been put forward to explain
their large travel distance but despite the big effort done
internationally, no general agreement on a comprehensive
rheological law has been yet achieved and many questions remain to be
answered.
We invite contributions to this session from numerical and experimental
modellers on studies of the rheological behaviour and on the propagation
and emplacement of these types of movements. This can include
development of new codes or improvement of existing
ones, physical modelling, back-analysis and benchmark exercises on
historic field event and/or laboratory experiments.
