DESCRIPTION:Dr. Rafid Al-Khoury\, Delft University\nComputational geoenvir
 onment is a field of research related to the earth planet. Almost all know
 n sciences that we are aware of are involved in geoenvironment. Geology\, 
 physics\, chemistry\, biology\, mathematics and engineering\, among others
 \, are involved. Nevertheless\, we remarkably know little about what is ha
 ppening beneath our feet. In 1985\, Richard Feynman stated\, “Strangely 
 as it may seem\, we understand the distribution of matter in the interior 
 of the sun far better than we understand the interior of the earth.". This
  statement is fairly valid until today! Though\, with the advent of comput
 ational sciences\, we are currently having better understanding of the ear
 th geology and the natural and manmade activities that are involved. Yet\,
  we are still at the beginning\, and further discoveries in geosciences an
 d geoengineering require a lot of efforts and investment. Advent in comput
 ational geoenvironment is one of the core elements for better understandin
 g of the earth interior behaviour\, and hence for an effective utilization
  of its space.\nThe field of computational geoenvironment is challenging\,
  inspiring and fascinating. It involves modelling fundamental elements for
  life on earth and humans wellbeing\, mainly: water\, energy\, materials a
 nd environment. Groundwater flow\, energy extraction\, energy storage\, mi
 ning\, waste storage\, contamination\, sequestration of CO2\, and geologic
 al events are only few examples of geoenvironmental activities. Such activ
 ities typically involve ambiguities and uncertainties stemming from the na
 ture of the geological formations and the complicated coupling between geo
 metry\, fluid and heat flow and mechanical forces. As a result of this\, e
 ngineering projects dealing with the interior of the earth usually do not 
 get the public support\, since the authorities so far are not very much ca
 pable of providing convincing evidences on the safety of constructing and 
 running such projects. The attempt by geoscientists to promote computation
 al geoenvironment as a field of research is not only timely\, but crucial 
 to promote advancing on understanding and mastering the geoenvironmental e
 vents and activities.\nIn this lecture\, I will give a short historical ba
 ckground of the development of poromechanics. I will briefly address physi
 cal processes and phenomena which are of particular interest to geoenginee
 rs and geoscientists. I will present relevant theories and approaches that
  are in use to model geoenvironmental processes. Then\, I will emphasize o
 n the challenges and approaches for formulating computational models essen
 tial for analyzing and designing geoenvironmental systems. Focus will be p
 laced on techniques for developing innovative computational tools\, and wi
 ll show how a good combination between the mathematical formulation and th
 e numerical procedure can make the complicated nature of geosciences feasi
 ble for engineering practice.
