Porosity of melamine sponge

WebImagine a water filled sponge. All of the holes in that sponge are water-filled. By squeezing that sponge we force the water out, similarly, by pumping an aquifer we force the water out of pore spaces. There are lots of terms in hydrogeology, most of which are very simple, but essential. Here are a few of the big ones and their meanings.
