STRESS 3 - A workshop co-sponsored by:

National Center for Earth-surface Dynamics (NCED) and Desert Research Institute (DRI)

CAMP GALILEE  | GLENBROOK, NV
OCT. 31 - NOV. 2, 2011 


Workshop Objectives

Power-laws and scaling are frequently observed in Earth surface morphology suggesting that heavy-tailed stochastic models and fractional PDEs may be powerful tools for describing processes and transport laws that take place on the Earth’s surface from the hillslope to the whole river network.  The STRESS 1 workshop, held in November 2007, catalyzed exploration of ideas, in research and applications, in the area of stochastic transport and emergent scaling in earth-surface processes.  Using novel statistical mechanical tools we studied emergent behavior of physical processes characterized by extreme deviation from average behavior on a small scale.  Approximately 20 manuscripts, including 15 in a special issue of Journal of Geophysical Research-Earth Surface, explore new models that can reproduce relevant features of sediment transport, retention, and deposition; deformation of bedforms; hillslope evolution and transport processes; landslide rupture and debris mobilization; and transport on river networks.

At the STRESS 3 workshop, we will again convene experts in Earth-surface processes and mathematicians and scientists who have successfully applied heavy-tailed stochastic theory and fractional differential equations in both Earth-surface science and other disciplines.  We will continue to identify:

  1. Geomorphic and hydrologic transport laws to which existing heavy-tailed stochastic theories and fractional calculus tools can be immediately applied
  2. Outstanding theory required for the development of novel scale-invariant models for Earth surface processes

The 3-day workshop will consist of oral sessions, group discussion, and breakout groups. Oral sessions will be held on previous applications of stochastic models at the Earth surface and open questions in Earth surface science that may benefit from novel mathematical approaches. We solicit only talks that fit within these categories. For example: physical motivation for non-local transport models, laboratory or field data to verify non-local mechanisms of transport, scale-dependence of local versus non-local models, relationship between non-linear and non-local models, non-local models of landscape evolution, types of models that explain multi-scaling transport rates. Because of increased interest in the STRESS workshops, we request only one abstract per research group.

Abstracts are due October 1, 2011.
