“…Qatar, Libanon, Oman, Yemen and the United Arab Emirates, however, show even positive mean trends between 0.2 and 4.2 mm/year, which is limited to the central, sparsely populated desert and mountainous areas, with the more densely populated coastal areas and the western and eastern parts showing slightly negative trends. For the eastern part of the United Arab Emirates, this coincides with the regional observation of Yilmaz et al (2020). It has to be mentioned though, that the results of the GRACE-derived data for the smaller countries of the Arabian Peninsula has to be interpreted with some care.…”

Groundwater resources in Euro-Mediterranean countries provide a large part of the population’s water supply and are affected to varying degrees by anthropogenic use and climatic impacts. In many places, significant groundwater-level declines have already been observed, indicating an imbalance between natural groundwater recharge and groundwater abstraction. The extent of changes in groundwater storage (GWS) in the period 2003–2020 is quantified for the Euro-Mediterranean region using the latest data from the Gravity Recovery and Climate Experiment (GRACE/GRACE-FO) satellite mission and recently reanalyzed ERA5-Land climate data from the European Centre for Medium-Range Weather Forecasts. The results are set in relation to the prevailing climate, the regional hydrogeological setting, and annual groundwater recharge and abstractions on country level. Analysis of the mean annual trends over the study period shows significant decreases in GWS in many countries of Europe, Northern Africa and the entire Arabian Peninsula. Overall, there are significantly negative trends in about 70% of the study region. The mean of the trends across the Euro-Mediterranean region is –2.1 mm/year. The strongest negative trends in GWS per country are observed in Iraq and Syria (–8.8 and –6.0 mm/year, respectively), but also countries in central and eastern Europe are affected by depleting aquifers. The results are a clear indicator of the already medium-term groundwater stress in the Euro-Mediterranean region, which is expected to increase in the future, and demonstrate the need for adapted strategies for sustainable groundwater management on a transregional scale in the context of climate change and population growth.

The increasing interest in hydrological studies in the United Arab Emirates (UAE) has resulted in the publication of several papers on hydrology and its broad use for addressing contemporaneous challenges confronting humans and the environment in the region. However, for several reasons, these efforts have remained invisible and unrecognized. This paper has reviewed the literature on hydrological research in the UAE to provide a comprehensive source of information for researchers, practitioners, policymakers, and other stakeholders. The documented studies were carefully selected, relying on a bibliometric analysis methodology of five phases to specify the boundary of the study area, adopt the primary keywords for the search, evaluate the obtained papers, exclude the non-conforming ones, and classify the final results into four distinguished topics—namely, rainfall analysis, urban growth and flood hazards, cloud seeding and changing climate, and groundwater situation and utilization. The evaluation process considered assessing the papers’ relevancy, authenticity, and coverage of the main issues of interest. In all, a total of 50 published papers were identified based on the specified criteria and reviewed. The main findings were first that the amount of rainfall over the UAE has been declining in the last decade, and this trend is expected to continue, although intensities are rising, suggesting shorter duration events. Secondly, the extensive urban growth in the country has resulted in increasing incidences of urban floods and declining groundwater recharge. Both of these are to be expected as consequences of the increased imperviousness from urbanization and the higher intensities from shorter-duration rainfall events. Thirdly, although the cloud-seeding program has proved to be successful in increasing precipitation amounts, the impact of this on flooding due to more extreme rainfall intensities and on air quality remains worrisome. Finally, groundwater analyses have shown that it is still the main freshwater resource in the country, but its long-term sustainability and quality are being threatened by the declining recharge. This calls for a national policy for groundwater management in the UAE to tackle the challenges associated with the increasing demand for water in all sectors of the economy. The study recommended addressing the gap in the hydrological literature of the UAE, specifically in the field of big meteorological data analysis, the socioeconomic impacts of urban floods, the impacts of climate change in urbanized regions, and the possibility of using alternative resources to recharge groundwater as part of sustainable water management.

“…Dolayısıyla, GAP bölgesindeki kuraklığın alansal ve zamansal tavrının, gidişinin ve hızının su kaynaklarının yönetimi ve risklerin paylaşımı açısından belirlenmesi büyük önem taşımaktadır. Küresel ısınma sonucunda meydana gelen iklim değişikliğinin izlenmesinde gidiş analizlerinde parametrik olmayan Mann-Kendall gidiş testi [19][20][21][22][23], Sen'in gidiş eğim metodu [24][25][26] ve Spearman'ın Rho testi [27][28][29] yaygın olarak kullanılan yöntemlerdir. Mann-Kendall gidiş testi analizlerinin genel olarak noktasal ölçekte [30][31][32][33] uygulandığı dikkati çekmekte; yorumların ise bölgesel ölçekte yapıldığı [34,35] görülmektedir.…”

ÖZİklim değişikliği, kuraklık gidişinin alansal ve zamansal yayılımının izlenmesinde farklı yaklaşımları ortaya konarak analitik çözümlemeleri ihtiyaç haline getirmiştir. Güneydoğu Anadolu Projesi (GAP) kapsamında; 19 242 km²'lik büyüklüğü ile sulama alanlarının %50'sine sahip Şanlıurfa'da yürütülen bu çalışmada, farklı yöntemler kullanılarak meteorolojik kuraklığın alansalzamansal eğiliminin ve büyüklüğünün (hızının) belirlenmesi amaçlanmıştır. Araştırmada; Şanlıurfa, Birecik, Akçakale, Ceylanpınar ve Siverek meteoroloji istasyonlarının 1965-2020, Bozova istasyonun ise 2000-2020 yıllarına ait yıllık toplam yağış ve ortalama yıllık maksimum sıcaklık serileri kullanılmıştır. Her istasyon için "Erinç Kuraklık/Aridite İndeksi"(EKİ) yıllık olarak hesaplanmış; EKİ serilerine Run (Swed-Eisenhart), Otokorelasyon, Mann-Kendall gidiş ve Sen eğim gidiş testleri %5 önem düzeyinde uygulanmıştır. Run ve otokorelasyon testine göre EKİ (Im) serilerinin bağımsız oldukları sonucuna varılmıştır. EKİ serilerinin medyan değerleri, Mann-Kendall gidiş testi ve Sen eğim gidiş analizi sonucunda hesaplanan istatistikler kullanılarak Coğrafi Bilgi Sistemi ortamında Ters Uzaklık Yöntemi ile; "Mann-Kendall Gidiş", "Sen Eğim Gidiş" ve "Erinç Kuraklık İndeksi" haritaları elde edilmiştir. Sonuç olarak Şanlıurfa ilinde kuzeyden güneye doğru EKİ değerlerinin azalan yönde anlamlı gidişler oluşturduğu, gidiş hızlarının (Im/yıl) azalan yönde artış gösterdiği belirlenmiştir. Beklenen bir şekilde, Suriye sınırına yaklaştıkça kuraklık şiddetinin artığı saptanmıştır. Atatürk, Birecik ve Karkamış barajlarının Şanlıurfa'daki kuzeyden güneye doğru olan alansal ve zamansal kuraklık gidişini Bozova haricinde engellemesinin beklenemeyeceği sonucuna varılmıştır. Anahtar Kelimeler: Meteorolojik kuraklık, Mann-Kendall, Sen eğim, gidiş haritası, Şanlıurfa.
