Aquifer
An aquifer is an underground layer of water-bearing permeable rock or unconsolidated materials (gravel, sand, or silt) from which groundwater can be extracted using a water well. The study of water fl...

Scientists at the Queen’s University Belfast have just invented the world’s first “porous liquid,” and it’s being hailed as a major breakthrough. But what on Earth is it?
Video: Man Claims He Caught Three-Eyed Fish In Gowanus Canal
If the man in the video is to be believed, the first Gowanus Canal monster is your regular run-of-the-mill three-eyed fish. It was always only a matter of time until the putrid toxic waters of the Gow...

Storativity
In the field of hydrogeology, "storage properties" are physical properties that characterize the capacity of an aquifer to release groundwater. These properties are Storativity (S), specific storage (...
Porosity
Porosity or void fraction is a measure of the void (i.e., "empty") spaces in a material, and is a fraction of the volume of voids over the total volume, between 0 and 1, or as a percentage between 0 a...
