Web(Rocks/Sediments that are very permeable make a good aquifer. This is because they allow the quick flow of water, which means that you can get a good flow from the well as well as quick recharge from precipitation, assuming that the aquifer is unconfined. Informal Assessment 1. Check students' comprehension by asking the following questions: WebPermeability is a measure of the degree to which the pore spaces are interconnected, and the size of the interconnections. Low porosity usually results in low permeability, but high porosity does not necessarily imply high permeability. It is possible to have a highly porous rock with little or no interconnections between pores.
