This article deals with the quantification of saltwater upconing below horizontal wells in freshwater lenses using analytical solutions as a computationally fast alternative to numerical simulations. Comparisons between analytical calculations and numerical simulations are presented regarding three aspects: (1) cyclic pumping; (2) dispersion; and (3) finite horizontal wells in a finite domain (...

This work systematically quantifies groundwater’s effect on the roof stability of underground openings in shallow coal mines and indirectly assesses potential for sinkhole formation. A specific stratigraphy was analyzed where opening instability can lead to formation, given geological conditions, overburden stratigraphy, depth openings. The groundwater recharge investigated as an individual rai...

A possibility of using bottom sediments from dam reservoirs in earth structures was considered. Sediments the Rzeszow reservoir (Poland) were used as research material, which, according to geotechnical standards, classified low permeable silt with high organic content. As fine, cohesive soil a coefficient permeability, can be sealing elements hydraulic engineering embankments. In order verify s...
