Accelerated erosion of a desert cliff due to uncontrolled sewage water disposal was investigated at the Sede Boqer Campus in the Negev, Israel An erosional cirque formed by this water was studied as a model simulating natural processes. The cliffs consist of loess and conglomerate underlain by soft marl, clay, and chalk. The rate of erosion is of the order of 5%-8% of the volume of water discharged. The rate of incision ranges from 10 2 to 13.3 m/yr and is several orders higher than that expected under normal rainfall conditions The introduction of this new hydrological factor resulted in a severe disturbance of the morphological balance in the vicinity of the cliffs, accelerated erosion, and generated circular slides
