Challenges & Revolutions in Hydrogeology, Geomechanics, & Cyberinfrastructure by Brandon Dugan, Rice University

  1. 1. Challenges & Revolutions in Hydrogeology, Geomechanics, & Cyberinfrastructure Brandon Dugan dugan@rice.edu Rice University
  2. 2. Science Goals and Needs 1) Understand deformation and fluid flow at geologic (preconditioning) and event (hazard) time and length scales 2) Fully coupled deformation, flow, reaction models - large strain behavior, complex rheology - strain/reaction-controlled material properties - continental margin evolution through slope stability 3) Easy access (uploader, user) database for data of all scales (bathymetry through mineralogy) 4) Improving utility of large data sets in numerical models (one permeability point vs pore-scale imaging)
  3. 3. Geologic and Hazard Models and Data Sawyer et al., 2012
  4. 4. Coupled Models Gas Hydrates Differing Space and Time Scales Facilitated by Linked Data Sets Reactions Influence Strength and Flow Phrampus and Hornbach, 2012 sv’ P*>sh’ n sh’= 1- n
  5. 5. Need for Easy Access Data Pressure VLFE activity C0010/0002 808/1173 Figure from Earl Davis
  6. 6. Impact of Easy Access Data - Tohoku Slip facilitated by pelagic brown clay (Moore et al., 2013) Clay shows rapid slip weakening (Ujiie et al., 2013) Fault zone has lower permeability (Tanikawa et al., 2013) Lin et al., 2013
  7. 7. Communication 1) 2) 3) 4) What experimentalists and modelers have What they want What they need Metadata – capture as much as possible, allow comment by others, adaptability (don’t know what we want until we need it/can’t find it)
