Stagnation and Pseudo‐Stagnation Lines for Separating 3D Groundwater Flow Systems in Tóthian Basins

Water Resources Research, Volume 61, Issue 5, May 2025.
Abstract Stagnation points have been found to be useful in characterizing groundwater flow regimes in 2D domains. However, knowledge on stagnation points in 3D basins is limited. In this study, we first derive a transient solution for 3D Tóthian basin flow under spatially undulating and periodically changing water table and examine the occurrence of ...

Mapping the interactions between rivers and sand dunes: Implications for fluvial and aeolian geomorphology [PDF]

, 2014
The interaction between fluvial and aeolian processes can significantly change Earth surface morphology. When rivers and sand dunes meet, the interaction of sediment transport between the two systems can lead to change in either or both systems. However,

Analysis of Geological Characteristics and Reservoir Potential Formation Damage Factors of Shallow Low‐Temperature Low‐Pressure Low‐Permeability Sandstone Reservoir

Energy Science &Engineering, Volume 13, Issue 4, Page 1544-1554, April 2025.
Experimental evaluation of water phase trap damage in tight sandstone reservoirs ABSTRACT The C‐S reservoir in the YQ district of Ordos basin, China, is located at a relatively shallow depth (240–720 m), with an original pressure coefficient of approximately 0.85 for the oil layer. Calculations indicate that the initial pressure of the oil layer ranges
