Inherited drainage - paleochannels and preferential groundwater flow
It is suggested that in a localized remnant of Kalahari sand at Dufuya, central Zimbabwe, groundwater flows in an integrated pattern inherited from the paleochannel network of the underlying gneiss. Contact springs occur at discrete localities along the Kalahari sand/gneiss boundary and are associated with spring sapping and land surface subsidence. Subsidence is presumed to be due to preferent...
متن کاملA new formulation to compute self-potential signals associated with ground water flow
Papers published in Hydrology and Earth System Sciences Discussions are under open-access review for the journal Hydrology and Earth System Sciences Abstract The classical formulation of the coupled hydroelectrical flow in porous media is based on a linear formulation of two coupled constitutive equations for the electrical current density and the seepage velocity of the water phase and obeying...
متن کاملMegacity pumping and preferential flow threaten groundwater quality
Many of the world's megacities depend on groundwater from geologically complex aquifers that are over-exploited and threatened by contamination. Here, using the example of Dhaka, Bangladesh, we illustrate how interactions between aquifer heterogeneity and groundwater exploitation jeopardize groundwater resources regionally. Groundwater pumping in Dhaka has caused large-scale drawdown that exten...
متن کاملForward Modeling and validation of a new formulation to compute self-potential signals associated with ground water flow
The classical formulation of the coupled hydroelectrical flow in porous media is based on a linear formulation of two coupled constitutive equations for the electrical current density and the seepage velocity of the water phase and obeying Onsager’s reciprocity. This formulation shows that the streaming current density is controlled by the gradient of the fluid pressure of the water phase and a...
متن کاملPathways of preferential arterial conduction.
Sir, In his reply to our earlier letter (1985; 53: 350) it seems to us that Dr T N James has misconstrued the point we wish to make. In our letter it is clear that when we speak of the division of the ventricular bundle branches we discuss the division of all the bundle branches. The relevant sentence is "if the tissue within the insulated sheaths is divided". Here we use the plural "sheaths" a...
