Fluid Transport in the Subsurface

Hours per week: 28 (course) + 14 (excercise);
Credits: 4 ETC

Brief description:

Elementary groundwater courses usually cover water flow and
tracer transport. However, real subsurface flow can be far more
complex and include many simultaneous physical processes
(e.g., gravity, capillary effects, chemical reaction).

The course “Fluid Flow in the Subsurface” illustrates the physical
and mathematical aspects of the flow that are relevant for
environmental applications (the latter include, e.g., groundwater
recharge and pollution, management of coastal aquifers, risk
assessment of underground disposals of nuclear waste,
geological sequestration of carbon dioxide).

Specific goals:
– Get acquainted with the complex processes occurring in the subsurface
– Understand similarities and differences between the descriptions of different physical processes
– Be able to formulate and solve (numerically) flow problems

– Introduction on flow and transport in permeable rocks.
– The problem of scales: from pores to aquifers.
– Multiphase flow; density driven flow; reactive transport.
– Numerical techniques for modeling subsurface flow problems
– Applications to environmental problems.
