WebIf the potentiometric surface is tilted, then fluid is moving across the basin in the direction of dip of the surface and the fluid pressure is caused by both hydrostatic and hydrodynamic forces (Fig. 4.14). Formation water salinity commonly increases in the direction of dip of the potentiometric surface (Fig. 4.15). WebAn attempt was made to obtain water-level measurements for the 2009 potentiometric-surface map from the wells used for the 1986–87 potentiometric-surface map. Well symbols with circles on the 2009 potentiometric-surface map (fig. 1) indicate wells that were used for the 1986–87 potentiometric-surface map.

A potentiometric surface is the imaginary plane where a given reservoir of fluid will "equalize out to" if allowed to flow. A potentiometric surface is based on hydraulic principles. For example, two connected storage tanks with one full and one empty will gradually fill/drain to the same level. This is because of atmospheric pressure and gravity.

WebThe water in a well drilled into the confined aquifer in this situation would rise above ground level, and flow out, if it’s not capped (well C in Figure 14.2.2). This is known as a flowing artesian well. Figure 14.2.2 A depiction of the water table and the potentiometric surface of a confined aquifer. [Image Description] WebThe reason behind these drawbacks is the formation of a water layer at the ion selective membrane (ISM)/electrode substrate interface. This water layer acts as an electrolyte reservoir where ion composition changes by even tiny transmembrane fluxes of the primary and interfering ions, which in turn affect the potential stability severely .
