Ingredients for Meandering River (Image 2)

Christian Braudrick of the University of California at Berkeley (pictured) and colleagues are the first to build a scaled-down meandering stream in the lab that successfully meandered through its flood plain for 130 hours, representing five to seven years of real time in the wild. The substrate seen behind Braudrick is composed of sand to represent real-life gravel; white, light-weight plastic for sand and alfalfa sprouts for deep-rooting vegetation.
