Dear Colleagues,
We would like to draw your attention to the " Lahars: Flow, sediment transport and deposition processes from direct observations, deposits, theory and experiments” session of the 2013 IAVCEI General Assembly, to be held in Kagoshima, Japan, July 20-24.
This session is sponsored by the IAVCEI Commission for Volcanogenic Sedimentation (http://vhub.org/groups/iavceicommissionvolcanogenicsedimentation).
3-8. Lahars: Flow, sediment transport and deposition processes from direct observations, deposits, theory and experiments
Lahars (debris flows and related sediment-water
mass flows) are frequent and deadly hazards at mountain-forming
volcanoes world-wide, with catastrophic losses of life and severe damage
to infrastructure occurring tens to hundreds of kilometres
from the source. As with other types of violent volcanic and
non-volcanic mass flows from which direct flow information is inherently
difficult to gather, field studies on a wide range of lahar deposits
have provided important clues towards our current understanding
their space- and time-variant behaviour (including lahar bulking, lahar
inundation and runout efficiency). However, a major obstacle in
facilitating this information in analytical or numerical models persists
to date in the lack of quantitative relationships
between flow dynamics and deposit characteristics. Another fundamental
problem persists in understanding the exact mechanisms of mass
growth/loss and their effect on flow-momentum evolution and how this
controls the rheology, flow transformation, and hazard
potential of laharic mass flows. This session will focus on:
- new views and concepts concerning the triggering, evolution, transport and depositional mechanisms of laharic mass flows
- direct field observations of lahars and their deposit characteristics,
analogue laboratory and large-scale experiments, and theoretical
modeling
- approaches linking physical models with direct field measurements of lahars and their deposits
