Approximate solutions for flows in unconfined double porosity aquifers
KN Moutsopoulos, JNE Papaspyros, M Fahs - Journal of Hydrology, 2022 - Elsevier
Although flow in unconfined double porosity aquifers occurs in most part of the world such
as in karst and crystalline aquifers, their hydrodynamic behavior is still poorly understood …
