On the kinematic processes which can give rise to the phenomenon of high-rate water injections into a porous medium
MetadataShow full item record
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.
