Aquifers which are bounded by a free surface (known as ‘water table’) at the upper boundary and a confining layer at the lower boundary are called unconfined aquifers (Aquifer 1 in Fig. 3.1). At the water table, water is at the atmospheric pressure, and hence unconfined aquifers are also called ‘water-table ...

The unconfined aquifer that extends over the entire urban plain (including the site under investigation) is hydraulically connected to the main surface water drainage network in the area (the Dora and Sangone rivers). This aquifer is hosted in Unit 1.Dar-Zarrouk parameters (D-Z) are employed to delineate the depth of weathering and aquifer characteristics. The longitudinal conductance ( S ) values are varying from 0.010 to 0.492 mhos. However, the greater variation in S is on account of heterogeneous rock structure lithologies indicating change in thickness and permeability and less S ...The principal aquifers and secondary hydrogeologic regions vary in depth, thickness, lithology, and transmissivity characteristics. Some principal aquifers underlie …Let’s solve an example; Find the storativity of a confined aquifer when the saturated thickness of aquifer is 10 and the specific storage is 2. This implies that; b = Saturated Thickness of Aquifer = 10. Ss = Specific Storage = 2. S = bS s. S = (10) (2) S = 20. Therefore, the storativity of a confined aquifer is 20.Aquifers hold groundwater in what is called the water table. This is one of the last stages of what is known as the water cycle, which is the natural cycle that water travels through on Earth. The ...
