WebIf a rock/sediment is porous, does that mean it is also permeable? (A rock/sediment can be porous without being permeable. If the spaces do not connect to each other, water cannot move through the rock/sediment.) What kind of rocks/sediments make a good aquifer? (Rocks/Sediments that are very permeable make a good aquifer. WebFeb 28, 2024 · aquifer, in hydrology, rock layer that contains water and releases it in appreciable amounts. The rock contains water-filled pore spaces, and, when the spaces are connected, the water is able to flow through the matrix of the rock. An aquifer also may be called a water-bearing stratum, lens, or zone. Wells can be drilled into many aquifers, and …

The falling head permeability test determines the perme ability of a material by measuring the time required for the water head to drop from a high level (h1) to a low level (h2). The permeability is then calculated using the equation geralt clean shaven
