In these aquifers, water can be found at different pressure levels, always above atmospheric pressure.<\/p><p>\u00a0<\/p><p class=\"translation-block\">Free aquifers, on the other hand, are limited by the water table in their upper part, and are directly recharged by the flow of water in the ground above that level. A special case of a free aquifer is the perched aquifer, which is nothing more than a small aquifer contained in an aeration zone of a main free aquifer and separated from it by a small aquiclude<\/p><p>\u00a0<\/p><p class=\"translation-block\">To better understand the physics of aquifers, it is important to mention, taking into account the hydrological cycle shown in Figure 1, that groundwater is in slow (but constant) movement within aquifers and between aquifers. It should also be noted that there is a continuous recharge of water by infiltration from the surface and from lakes and groundwater flows; and, at the same time, a continuous subtraction of groundwater by seepage into effluents and by pumping from deep wells.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<section class=\"elementor-section elementor-top-section elementor-element elementor-element-dc9d112 elementor-section-full_width elementor-section-height-default elementor-section-height-default\" data-id=\"dc9d112\" data-element_type=\"section\" data-e-type=\"section\">\n\t\t\t\t\t\t<div class=\"elementor-container elementor-column-gap-default\">\n\t\t\t\t\t<div class=\"elementor-column elementor-col-100 elementor-top-column elementor-element elementor-element-0a3795b\" data-id=\"0a3795b\" data-element_type=\"column\" data-e-type=\"column\">\n\t\t\t<div class=\"elementor-widget-wrap elementor-element-populated\">\n\t\t\t\t\t\t<div class=\"elementor-element elementor-element-8c113eb elementor-widget elementor-widget-heading\" data-id=\"8c113eb\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t<h3 class=\"elementor-heading-title elementor-size-default\">Porosity (n)<\/h3>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<section class=\"elementor-section elementor-top-section elementor-element elementor-element-5741584 elementor-section-full_width elementor-section-height-default elementor-section-height-default\" data-id=\"5741584\" data-element_type=\"section\" data-e-type=\"section\">\n\t\t\t\t\t\t<div class=\"elementor-container elementor-column-gap-default\">\n\t\t\t\t\t<div class=\"elementor-column elementor-col-100 elementor-top-column elementor-element elementor-element-2d83e41\" data-id=\"2d83e41\" data-element_type=\"column\" data-e-type=\"column\">\n\t\t\t<div class=\"elementor-widget-wrap elementor-element-populated\">\n\t\t\t\t\t\t<div class=\"elementor-element elementor-element-ba6cc58 elementor-widget elementor-widget-text-editor\" data-id=\"ba6cc58\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<p class=\"translation-block\">Porosity is one of the main properties of an aquifer, and is defined as the ratio between the volume of interstitial space contained in the solid structure of a material (Vv), and its total volume (V).

the volume of water released for storage, per unit area and per unit change in load normal to that area (Ferris et al, 1962).<\/p><p>\u00a0<\/p><p class=\"translation-block\">In free aquifers, Cs \u2248 0.2, because water drains by gravity from the interstitial pores. In confined aquifers, on the other hand, the pores remain saturated, but there is a low volume available for storage when the load is reduced, due to the elasticity of the aquifer. Typical Cs values for confined aquifers vary between 0.0005 and 0.001. For rock mass aquifers, Cs can be several orders of magnitude lower than the above values, due to the low effectiveness of porosity and the rigid structure of this type of aquifer.<\/p><p>\u00a0<\/p><p>Now that we have a better understanding of what an aquifer is, we will be able to approach its study from a different perspective, fundamentally oriented towards making its exploitation sustainable over time.
