Spatio-temporal drought analysis in the Trakya region, Turkey

Abstract: Since droughts are natural phenomena, their occurrence cannot be predicted with certainty and thus it must be treated as a random variable. Once drought duration and magnitude have been found objectively, it is possible to plan for the transport of water in known quantities to drought-stricken areas either from alternative water resources or from water stored during wet periods. The summation of deficits over a particular period is referred to as the drought magnitude. Drought intensity is the ratio of drought… Show more

“…In Poland, as a result of an air temperature increase, especially in the periods of April-May and July-August and the number of hours with sunshine in May and in the JulyAugust period, with no increase in the total precipitation, drought in the vegetation season (April-September) will most probably intensify even more year by year (Kożuchowski and Degirmendzic, 2005;Kalbarczyk, 2009). Similar changes in the occurrence of atmospheric drought were recorded not only in countries neighbouring Poland (Brázdil et al, 2009;Dubrovsky et al, 2009), but also in other parts of Europe (Sirdaş, 2003;Tonkaz, 2006;Livada and Assimakopoulos, 2007;Croitoru et al, 2008) and even the world (Chen et al, 2009;Logan et al, 2009).…”

“…On the other hand, in central regions of the USA (in the river Kansas basin) a significant decrease in the SPI value was noted (an increase in frequency and intensity of drought occurrence), and in the western and eastern parts -a significant increase (Logan et al, 2009). Like in Poland in the years 1966-2005, research in many regions of the world confirm very high spatial variability of the occurrence of atmospheric drought in a multi-annual perspective (Bonaccorso et al, 2003;Hisdal and Tallaksen, 2003;Sirdaş , 2003;Zhang, 2004). In Poland, water requirements of cucumber in the vegetation season of plants, on average, amount to 350-450 mm, and water consumption is different in particular stages of its growth and development (Dzieżyc and Dzieżycowa, 1986;Dzieżyc et al, 1987;Ż arski, 1989).…”

“…Pongracz et al (2003) modelled the relationship between the climatic forcing and droughts in Central Europe. Sirdaş & Şen (2003) studied the drought properties of Turkish precipitation records at different truncation levels. The threshold level below which the drought is assumed to occur and the minimum area that it should cover are drought characteristics decided before the analysis.…”
