DOI: 10.1002/esp.4868
Abstract: Extreme high‐magnitude and low‐frequency storm events in arid zones provide the necessary runoff to entrain sediments from source areas and therefore dictate the linkages between hillslopes and channels. Nevertheless, the erosive impact of large storms… read more here.
