Elde edilen sonuçlar ışığında Yağış parametrelerinde Trakya Bölgesinde gözlemlenen uzun yıllık toplam yağış 1119.1 mm olarak belirlenmişken en düşük toplam yağış ise 430 mm olarak hesaplanmıştır. Mevsimsel bazdaki yağışın dağılım durumuna bakıldığında kış aylarında gözlemlenen uzun yıllar ortalaması toplam yağış miktarı maksimum olarak 451.5 mm iken minimum gözlemlenen toplam yağış miktarının ise 116.6 mm dolaylarında olduğu hesaplanmıştır. İlkbahar aylarındaki uzun yıllık toplam yağış miktarındaki dağılıma bakıldığında maksimum olarak 206.2 mm yağış gözlemlenmişken minimum olarak ise toplamda 106.6 mm civarında bir yağışın olduğu belirlenmiştir. Yaz aylarındaki dağılım ise maksimum olarak 176.7 mm iken minimum olarak ise 42.3 mm civarındadır. Trakya Bölgesinde uzun yıllar ortalaması olarak hesaplanan sonbahar yağışlarının toplamının en yüksek değeri ise 320.5 mm olarak mekânsal olarak belirlenmişken minimum olarak ise 117.8 mm civarında toplam bir yağışın oluştuğu hesaplanmıştır. Tüm Meteoroloji istasyon verilerinin değerlendirilmesi sonucunda bölgede ortalama uzun yıllık toplam yağışın ise 718.8 mm olduğu hesaplanmıştır. Yapılan trend analizleri sonucunda ise ortalama olarak aylık ve yıllık bazda toplam yağışlarda azalan yönde, ortalama ve maksimum sıcaklıklarda ise artan yönde bir trend olduğu görülmüştür. Mevsimsel bazda ise kış ayları için maksimum sıcaklıkta artan trend, ilkbahar aylarında maksimum ve ortalama sıcaklıkta artan yönde, toplam yağışta ise azalan yönde bir trendin olduğu görülmüştür. Yaz aylarında ise minimum, ortalama ve maksimum sıcaklıklarda artan yönde, toplam yağışta ise azalan yönde bir trend gözlemlenmiş olup sonbahar aylarında ise ortalama ve maksimum sıcaklıklarda artan bir trendin olduğu, toplam yağış miktarında ise azalan bir trendin olduğu belirlenmiştir.In this study, in Thrace Region total and maximum rainfall between long term meteorological data recorded in the State Water Works General Directorate of the 17 meteorological stations and Meteorology of the General Directorate 8 station data depending on the recording-year average from 1970 to 2011 year, the average, minimum and maximum temperature values for monthly, annual and seasonal values are subjected to trend analysis. Made in trend analysis and the Mann-Kendall statistics Spearman's Rho test is applied in the evaluation it has revealed temporal changes in the status of climate parameters. In this study, particularly Geographic Information Systems (GIS) has benefited from technology is spatial analysis was performed for the temporal change of drought and climate change using geostatistical methods in GIS have been used effectively in this sense Arc GIS 10.3.1 GIS software. spatial distribution of climate variables using Spline entelpolasyo approach within the context of spatial analysis are discussed. The results obtained in the light of the observed precipitation parameter in the Thrace region long annual rainfall 1119.1 mm, the lowest total rainfall was calculated as been set to 430 mm. The average observed for many years in the winter months when we look at the distribution of the rainfall situation a seasonal basis as the maximum total amount of rainfall is 451.5 mm, while the minimum observed in the total amount of rainfall is estimated to be around 116.6 mm. Looking at the distribution of the maximum annual amount of precipitation in the spring long observed that when 206.2 mm of rainfall as a minimum if it is determined that there is a total of 106.6 mm rainfall around. The distribution of a maximum of 176.7 mm in the summer, while the minimum is about 42.3 mm. The highest value is the sum of many years, calculated as the average precipitation fall in the Thrace region as dictated spatially 320.5 mm while the minimum is calculated as consisting of a total of around 117.8 mm rainfall. All the meteorological station of the average annual precipitation in the region in the long end of the evaluation of the data is estimated to be 718.8 mm. Made trend analysis result of the average total rainfall in the direction of decreasing the monthly and annual basis, and the average maximum temperature was found to be a growing trend direction. The maximum temperature on a seasonal basis in the growing trend for winter, spring, and in the direction of increasing the average maximum temperature, while the total rainfall was found to be a trend in the decreasing direction. In summer, minimum, average, and in ascending direction in the maximum temperature, while the total rainfall has been observed a trend in decreasing direction autumn as did a rising trend in the average and maximum temperature, while the total amount of precipitation was determined to be descending a trend

Evaluation of Irrigation Water Quality of Aksaray Region By Using Geographic Information System

In this study, the quality of irrigation water was determined in Aksaray region which is one of the most important agricultural lands of Turkey, the facts causing pollution were specified and the precautions that should be taken were discussed. Within the scope of this study, 38 samples were taken from the water of 24 wells, 4 dams, 9 ponds and 1 source water. In order to use the data more effectively, irrigation water quality index map of Aksaray region including the results of the samples (EC, SAR, B, Cl-, NO3-, HCO3- and pH) was prepared by using Geographic Information System (GIS). According to irrigation water quality index map, all surface water sources were found to be suitable for irrigation with high and medium irrigation water quality index. EC, SAR, Cl, HCO3 values were found as high in Acipinar well and Aratol well regions whereas EC and Cl values were high in Taspinar well region. It was determined that underground water sources have low irrigation water quality index value along in the range of Taspinar region and Tuz Lake whereas they have generally medium irrigation water quality index value. The soil being heavy-texture and salty structure in the region and the level of ground water being high were caused by lack of adequate drainage system. For this reason, good and adequate drainage system should be configured in order to provide no increase in salt accumulation in the soil, to get an opportunity for more appropriate land use and to increase the yield per unit area
