. Athmospheric pumping studied by the Nuclear Test Containment Program at LLNL

. Amplitude of the motion in the fractures is controlled by the seepage of fluid in and out of the matrix blocks.

. Double porosity model:
permeability = Durchlassgeschichte
porosity = Speichergeschichte

. Aber wenn porosity (matrix or fracture) speichert, wie koennte eine Funktion dazu aussehen? Was ist denn mit porosity = 100% (fracture)?
