Supervised Classification of an Arid Groundwater Flow System

Symposium on the Application of Geophysics to Engineering and Environmental Problems 2001, 2001
This investigation addresses the hydrogeology of the White Sands National Monument (WSNM) to determine the characteristics of an arid groundwater flow system using remote sensing methods. A supervised classification using Landsat-7 data sets were used to identify the different terrains leading to a better understanding of the White Sands, where depth ...

Uranium in groundwater – The importance of hydraulic regime and groundwater flow system's understanding

Journal of Environmental Radioactivity, 2018
Uranium and other natural radionuclides are common components in groundwater, but they are not routinely measured. In drinking water their total activity is screened, but in the evaluation of the measured values usually the aquifer material is only considered.

Groundwater flow systems and slope stability

Canadian Geotechnical Journal, 1977
Slope stability analyses carried out in terms of effective stress require an understanding of the distribution of pore-water pressures in a slope. This understanding must be based on a knowledge of the groundwater flow system, which is in turn dependent on the regional geologic environment and the configuration of hydraulic conductivity contrasts ...

Modelling Groundwater Flow Systems

1996
The regional flow systems analysis should start with a general analysis of the problem in terms of boundary conditions, homogeneity of the flow domain scales: lateral scales and associated depth scales, time-scales.

Gravitational Systems of Groundwater Flow

2009
This book recognises groundwater flow as a fundamental geologic agent, and presents a wide-ranging and illustrated overview of its history, principles, scientific consequences and practical utilization. The author, one of the founding fathers of modern hydrogeology, highlights key interrelationships between seemingly disparate processes and systems by ...

Groundwater Flow Systems and Hydrocarbon Migration

1996
Toth has gradually extended his concept of a hierarchy of flow systems, originally developed for small drainaige basins, to large sedimentary basins with large width-, depth- and time scales, for instance the study of gravity-induced cross-formational flow of formation fluids in the Red Earth Region of Alberta, Canada (Toth, 1978) and the study of oil ...

Groundwater flow to a system of drainage canals

Water Resources, 2006
A classical model of groundwater flow to a system of drainage canals is considered within a framework of a two-dimensional steady-state problem. The solution to this problem is derived based on the Riemann-Schwarts principle of symmetry. This solution yields simple analytical relationships expressed in terms of special or elementary functions ...
