The climate of the region is generally hot and dry summers, while winters are cool and rainy. A major part of the precipitation is in the form of rain. Edirne, Kirklareli and Tekirdag provinces, we examine the data corresponds to an arid climate year around 10-12 years. That the drought in 1985, 2000, 2001 and 2008, rainfall has decreased in all provinces. 603.5 mm in Edirne, Kirklareli Provinces and 549.9 mm average rainfall is 588.1 mm in Tekirdag, 1985, respectively 452.9, 444.0 and 483.9 mm was recorded at around. That is because rainfall has decreased in approximately 20-25%. Later in the year 2000 and 2001 in Edirne Province (419-467.2 mm) 25- 31%, in Kirklareli Province (326.6-467.2 mm) and 20-41% in the 2000s Tekirdag Province (410.1 mm) to 30% the rate was little precipitation (11). Again, Edirne Province in 2008 (387.0 mm) of 36%, in Kirklareli Province (424.5 mm) and 23% in Tekirdag Province (304.2 mm) of rainfall less than 48%. Particularly agriculture that the volatility in precipitation constitutes significant pressure on other water sources (11). Edirne Province in terms of average temperature changes in long-term average of 13.5 °C and 12.0 °C Kirklareli, Tekirdag is 13.9 °C. Temperature increases are seen in light. In recent years, Edirne, Kirklareli and Tekirdag Provinces average temperature has exceeded the 14.0-14.5 °C and has risen. Yet all three provinces as well as in the dry years 2000 and 2001, the average temperature exceeded 14.5°C. This means that both reduced precipitation, as well as the temperature raised, people, plants and animals has increased the need for water. Increased evaporation from dams and ponds are in use can be significantly reduced water quantities. Groundwater resources are also fed a sufficient amount (11). The presence of this one occupies an important place in Istanbul city. A large part of Thrace region is surrounded by the sea. The land borders but also the borders of the Republic of Turkey, Bulgaria and Greece. Bulgarian border (200 km), starting on the coast of the Black Sea from the mouth of the Ergene River is attained near the Meric river Kapikule districts. After this point, the Turkey-Greece border (204 km) begins. This boundary follows the beginning of the Meric River, Edirne-Karaagac Province to leave in Turkey in this way alone through the western part of the Meric River, reaching the Aegean Sea. Examined field position is shown in Figure 1.
