Steady groundwater flow as a dynamical system
Water Resources Research, 1994Dynamical systems describe the time evolution of moving spatial points under the influence of a smooth, bounded vector field. The theory of these systems is focused on the global properties of their flow paths, not on their integration, and so gives general, qualitative information that does not depend on the details of the spatial variability of the ...

Three‐dimensional modeling of groundwater flow systems
Water Resources Research, 1978Practical aspects of three‐dimensional (3‐D) modeling of groundwater flow systems are closely examined. A Galerkin finite element model is designed with a view to providing flexibility, user convenience, and a high degree of efficiency, qualities which are critical to the success of 3‐D modeling of real systems.

Permafrost thaw in a nested groundwater-flow system
Hydrogeology Journal, 2013Groundwater flow in cold regions containing permafrost accelerates climate-warming-driven thaw and changes thaw patterns. Simulation analyses of groundwater flow and heat transport with freeze/thaw in typical cold-regions terrain with nested flow indicate that early thaw rate is particularly enhanced by flow, the time when adverse environmental impacts

Groundwater flow systems in torbiditic units
2004The paper deals with the analysis of hydrological and hydrochemical data coming out from 2 distinct monitoring projects of springs and creeks in 5 mountainous watersheds in Northern Apennines (Italy), located inside the outcropping area of “Marnoso Arenacea” arenaceous torbiditic unit.

The Cuitzeo groundwater flow system in central Mexico is facing challenges due to intensive groundwater extraction, nitrate pollution, and a decline in groundwater levels. To understand the processes underlying these environmental impacts, we used compiled data from 2013 and employed cluster analysis to identify distinct groups.

Groundwater Flow Systems and Accumulation of Evaporite Minerals
AAPG Bulletin, 1970ABSTRACT The literature on evaporite mineral deposits suggests a functional relation between the origin of these deposits and groundwater flow systems. Comparison of reported spacial variations of groundwater quality with pertinent solutions to flow equations under specified boundary conditions reveals that quality of groundwater is a

Numerical Simulation of Advection in Groundwater Flow Systems
1986Since the primary transport mechanism in a subsurface flow is advection, accurate determination of the velocity of the carrier fluid percolating through the porous medium is extremely important. Computer-based groundwater motion simulators conventionally use pressure as the primary variable, and after the pressure field has been calculated, the ...
