A climate impact of dam lake and Recep Yazicioglu Gokpinar dam lake sample
Barajlarin ekoloji uzerinde olumlu ve olumsuz etkileri vardir. Bolge ikliminde meydana gelen degisim en onemli etkilerinden biridir. Bu calismada, Vali Recep Yazicioglu Gokpinar Baraj Golu'nun Denizli Ili iklimine etkisi arastirilmistir. Calismada Denizli ili meteoroloji istasyonundan alinmis maksimum, minimum ve ortalama sicaklik, ruzgar hizi, yagis ve buharlasma verileri kullanilmistir. Baraj yapilmadan onceki ve sonraki verilerdeki mutlak degisimler incelenmistir. Baraj yapimindan sonra maksimum, minimum ve ortalama sicakliklarda tum aylarda artis gozlenmistir. Yagis miktarlarinda baraj yapildiktan sonra, onceki doneme gore Ocak, Subat ve Ekim aylarinda artis oldugu halde, diger aylarda azalma oldugu gozlenmistir. Buharlasma ve ruzgar hizi parametrelerinde cok az degisim olmustur. Trend analizi icin Lineer Regresyon, Mann Kendall ve Sen yontemleri kullanilmistir. Tum yontemlerde maksimum, minimum ve ortalama sicakliklar ve ruzgar hizinda artan yonde bir egilim oldugu, buharlasma ve yagista onemli bir egilim olmadigi gorulmustur. Dams have both positive and negative effects on the environment. The most important effect can be defined as the regional climate change. In this study, the impact on Denizli city climate of Vali Recep Yazicioglu Gokpinar Dam Lake was determined. In this study, Denizli city meteorological station (maximum, minimum and mean temperatures, total precipitation and wind speed) data were used. Before and after from the dam construction; absolute changes are examined. After the dam construction; maximum, minimum and average temperature increase was observed in all months. A rainfall was observed to be increased in January, February and October on after dam construction, but another times was observed to be decreased. The evaporation and wind speed parameter has been little change. Linear regression, the Mann Kendall and Sen's Method for trend analysis were used. All techniques considered here consistently reveal that there are upward trend in maximum, minimum and mean temperatures, wind speed, no trend in precipitation and evaporation.
