The Hyporheic Zone

  • Video Reveals Little Known World of Riverbeds

    Not all that you see when you look at a river is above ground.  There is a hidden world that exists beneath the bottom, in the vast network of interconnected spaces between the pebbles that make up the streambed.  Scientists call this the hyporheic zone.  The hyporheic zone is a place where water flowing in the stream channel percolates down into the streambed, mixes with groundwater, and reemerges to join the surface water somewhere downstream.  The hyporheic zone is important because it helps to cool, filter, and cleanse the stream water, and also because strange, vital things are living there.

    Watch “The Secret Life of Rivers,” a short video introduction to the world of the hyporheic zone.
