Session ID#: 16008

Session Description:
Coupled deformation and fluid flow underlie a wide range of fundamental behaviors and processes in the shallow crust, including rock and sediment strength; mass, heat and volatile fluxes; and the links between these fluxes and subsurface biological communities. Recent advances have the potential to illuminate these fundamental processes through the application and development of coupled models that describe deformation and fluid flow in response to the evolution of the full stress field, in combination with experimental studies that extend established soil mechanics concepts to geologically relevant higher stresses and longer time scales. Examples include pore pressure in subduction zones and sedimentary basins, slope failures, subglacial till deformation and hydrology, pressure and stress interaction around deep-well injection, stress and strain surrounding complex structures, and dynamic fault zone slip processes. We welcome experimental, theoretical, and field-based contributions describing deformation behavior and rheology, and theoretical approaches to illuminating earth behavior.
