The dams that have been built on most rivers (two-thirds of the world's rivers do not run free) often stabilize river flow by increasing flows below the dams during droughts and degreasing the amount of flooding during periods of high rainfall. Using the intermediate disturbance hypothesis , predict how stabilizing flows would affect the diversity of river organisms below reservoirs .
