On the kinematic processes which can give rise to the phenomenon of high-rate water injections into a porous medium
Summary
This manuscript is on the phenomenon of high rate water
mass injections in to a saturated confined aquifer, in aid of a better
understanding of the dewatering methodology known as
"Düsensauginfiltration" (DSI), or less common "Jet Suction
Infiltration" (JSI). In this work, of exploratory nature,
we present a general conceptual model for
this phenomenon, the result of a literature review. Further, based on theoretical
considerations on flow and deformation kinematics as well as the
derivation of a Lagrangian-Eulerian balance principle, we present
six possible fundamental kinematic processes which may underlie the
phenomenon. In future research the relevance of these processes can
be investigated, for example laboratory experiments, and may uncover
the kinematics giving rise to the phenomenon.
