Abstract

The efecs of urbanization and cirmate change impacto he flod nsk of rw governorates in Fgypt were analyzed. Non-parametric change point and trend detection algorithms were applied to the annual rainfall rainfall anomaly, jand monthly surface runoff data generated by the Curve Number method over 1948-2014 were also analyzed to detect rhe effects of urbanization on tne surlace runolt Lastiy, al13 decsion support system was developed to delineate food susceptibility zones forthe wogaveoeTheican ecie inenualrainland rainllanomnaly ater 1904at8.96and15.3mmidecade |ruspectively was likcty dueto climate change impact, especially significant warming trend since 1976 at 0.16"C/decade, e owueclbye oh ssceeokod.ooawt-boy boeatzctozbcscoeolcocano cobcoestom. sbsoe iep0) cecs oi crbaanaion to foc cek are clear、 because despite a decline in rainfall, the annual surface runoff and runoff anomaly show positive trends of 12.7 and of 1Ą,39 mmidecade, respectively.
