DFNE 2018

ARMA 2018 and the Seattle rock mechanics community are pleased to host DFNE 2018, the 2nd International Conference on Discrete Fracture Network Engineering. Building on the success of DFNE 2014 in Vancouver, this international meeting of engineers and geoscientists will bring together practitioners from around the world who use discrete fracture network engineering in the characterization of fractured rock masses and solution of engineering problems. This rapidly expanding area of engineering has wide applications, including underground and surface mining, underground nuclear waste disposal, petroleum geomechanics, geothermal energy, civil engineering, fractured aquifer characterization and cleanup and natural hazards.

The DFNE 2018 organizing committee invites you to join us to share your ideas and experiences in the development and practical use of this technology. The conference is timed to integrate with ARMA 2018 that takes place from June 24 – 27, 2018, also in Seattle.

DFNE 2018 will be held in scenic downtown Seattle, Washington, USA. Situated within the Puget Sound in the Pacific Northwest, this city is surrounded by water, mountains and evergreen forests
