Description :
The palaeohydrology of Nahal Zin, a 1400 km2 catchment in the hyperarid Negev Desert, is inferred from slackwater deposits and palaeostage indicators in a canyon near its lower end. The palaeoflood record includes 28 floods over the last 2000 years. The clusters of floods around 1000 years BP and again during the last 60 years are characterized by high flow magnitudes. Periods with many floods correspond well to periods with high Dead Sea levels and are probably relatively wet periods. Fluctuations in the frequency of floods are typical of periods of transition from one climate regime to another.
