A a semi-porous material called Flexi-Pave absorbs 3,000 gallons of water per hour. The products of these shredders are used by collectors, such as Hydropsychidae, and further downstream algae that create the primary production become the main food source of the organisms. There are salt water rivers in different places of the world where ground water flows in contact with salt layers.
