Experimental Study of Groundwater Flow
International Journal of Online and Biomedical Engineering (iJOE), 2009 This paper describes an experimental setup for groundwater flow studies with small scale models, developed for the Soil Mechanics course offered to Civil Engineering Master students at FEUP. Relevant quantities, such as the piezometric head and total discharge, can be measured, while flow lines may be visualized.

Deep Underground Science and Engineering, Volume 1, Issue 2, Page 148-164, December 2022., 2022 We conducted a new approach of mine water‐deep geological storage, the results showed that the hydrogeological feasibility of Baotashan coarse sandstone (BCS) was impressive and useful for real project. The effective porosity of BCS aquifers ranged from 1.36% to 3.46% and the capacity of mine water geological storage was 0.455–1.266 Mm3 for 1 km2 in ...

Equations for Long-Range Groundwater Flow and Water Table Evolution [PDF]
arXiv, 2022 These are notes that I compiled while studying the equations of long-range groundwater flow for my first paper. By "long-range," I mean horizontal distances that are significantly greater than the vertical thickness of the aquifer, in addition to some other assumptions discussed below. None of this material constitutes original development of important

Groundwater flow in eastern Ottawa
Canadian Geotechnical Journal, 1970 A mile-long line of piezometers were installed at various depths in a clay terrace system east of the City of Ottawa. Measurements indicated a significant downward piezometric gradient through the clay layer to the underlying bedrock. The downward flow of water through the clay affects both existing effective stresses and the stress history of the ...

Angewandte Chemie, EarlyView.A lattice and surface engineering strategy was employed to synthesize a novel core‐shell nanomaterial for superior reductive dechlorination of trichloroethene. In this design, FeNi serves as the core and FeS as the shell. Core composition and shell properties interactively determine materials’ performance, and the optimal material exhibited 242.7‐fold ...

Groundwater flow in a fissurised porous stratum
Networks & Heterogeneous Media, 2010 Barenblatt e. a. introduced a fluid model for groundwater flow in fissurised porous media. The system consists of two diffusion equations for the groundwater levels in, respectively, the porous bulk and the system of cracks. The equations are coupled by a fluid exchange term. Numerical evidence suggests that the penetration depth of the fluid increases
