Sediment yield from the Nahal Nehushtan watershed (11.9 km2) located in the Timna Valley in southern Israel was determined by assessing stratigraphic sections in its 60-year reservoir deposits. Stratigraphic correlation between event couplets allowed for quanti\ufb01cation of sediment yields representing 13 former \ufb02ow and \ufb02ood events. Based on the sediment volume in the reservoir, the 29.8 t km\u22122 year\u22121 average speci\ufb01c sediment yield is one of the lowest among other studied warm deserts. Among the event layers, the thickest layer, deposited by a \ufb02ash \ufb02ood caused by a single short rain event, contributed 31% of the total sediment yield. Based on event reservoir sedimentation from watersheds located in several hyper-arid areas in the Middle East and North America, we demonstrate that sediment yield increases with drainage area as expected and mean annual sediment yield increases in hyper-arid areas with \ufb02ood frequency. Our quantitative<br \/>\nresults, together with previous studies of hyper-arid areas, provide complementary evidence of \ufb02uvial sediment transport\u2014the main landscape designer in hyper-arid \ufb02uvial landscapes.<\/p>\n<p><strong>Keywords:<\/strong> sediment yield; \ufb02ash \ufb02ood; hyper-arid; stratigraphy; event-layer; reservoirs<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Author: Rachel Armoza-Zvuloni , Yanai Shlomi , Itay Abadi, Rachamim Shem-Tov\u00a0 and Jonathan B.
