SUMMARY:CPEP Seminar – Modeling Glacier and Ice-shelf Flow and Fracture U
 sing Computation and Data
DESCRIPTION:Speaker: Ravi Duddu\, Associate Professor of Civil and Environm
 ental Engineering\, Vanderbilt University\n\nThe dynamic ice mass loss fro
 m the Antarctic and Greenland ice sheets into oceans is the greatest sourc
 e of uncertainty in predicting sea level rise. Fracture propagation in gla
 ciers and ice shelves can accelerate ice flow and cause the detachment of 
 icebergs\, thus significantly influencing ice mass loss. It has been hypot
 hesized that hydrofracturing of glaciers and ice shelves followed by enhan
 ced basal sliding and ice cliff failure could contribute to rapid sea leve
 l rise over the coming centuries.\n\nIn this presentation\, Duddu will pro
 vide an overview of his recent work on simulating fracture propagation in 
 glaciers and ice shelves using viscoelastic damage mechanics models. Duddu
  will describe their application in the context of crevasse propagation an
 d ice cliff failure in marine terminating glaciers\, rapid supraglacial la
 ke drainage events enabled by turbulent hydraulic fracture\, and rift prop
 agation in ice shelves leading to tabular iceberg calving.\n\nIn each case
 \, he will discuss the use of data from laboratory experiments and field/s
 atellite observations to inform physics-based computational models.\n\nAck
 nowledgements: This work is funded by the NSF Antarctic Glaciology and NAS
 A Cryosphere Science programs.\n\nThis seminar can also be viewed via our
  live stream.\n\nHosted by the Climate\, People and the Environment Progr
 am (CPEP).
