英文摘要	Study region: Southern Judean Desert, Israel. Study focus: To extend the flood record in two basins in the Judean Desert for facilitating the quality and reliability of the flood frequency analysis (FFA). New hydrological insights for the region: The hydrological data for The Judean Desert streams is partial to none. This study applied palaeoflood hydrology method, which analyzes sedimentological evidence of past large floods in two streams. One basin (N. Ze' elim, 250 km(2)) yield maximum palaeo-discharge of 900 m(3) s(-1) and the other (N. Rahaf, 55 km(2)) 1250 m(3) s(-1) (1.3 and 2.3 times larger than the maximum measured floods, respectively), for records of 500 and 5000 years, respectively. Combining these data with measured and historical data produced a palaeohydrological data-base of several hundred to thousands years long. These data updated the regional envelope curves for the maximum peak discharges. The improved FFA caused a decrease for the 100-year flood in the larger basin, from 1750 m(3) s(-1), for the systematic record only, to 760 m(3) s(-1) (43 %) for the combined records, and from 1260 m(3) s(-1) to 980 m(3) s(-1), in the other basin (77 %). The FFA for the systematic + historic data only, overestimated the frequency of the large floods due to their short and discontinuous records. The extension of the record with the palaeoflood data reduced the peak discharge values for different return periods and significantly enhanced FFA reliability.
