Samsun, Türkiye'de Kıyı Değişimlerinin İncelenmesi

Öz

Bu çalışmada, Samsun il merkezinde, kıyısal alanda yıllar içinde dolgu yapılarak meydana gelen değişimleri hesaplamak amaçlanmıştır. Çalışma alanına ait mevcut hava fotoğrafları ve ortofoto ayrıntılı olarak incelenmiştir. 1935 yılından itibaren yaklaşık periyodik aralıklı hava fotoğrafları ve 2012 tarihli ortofoto kullanılarak ArcGIS 10 programının ArcMap modülü ile çalışılmıştır. Samsun ilinde kıyısal bölgede dolgu alanı miktarı, 1935-1972 yılları arasında 852.286 m2, 1972-2006 yılları arasında 1.478.218 m2, 1935-2006 yılları arasında 2.330.504 m2 ve 2006-2012 yılları arasında 238.316 m2 olarak belirlenmiştir. İlde 1935 yılından 2012 yılına kadar yapılan dolgu miktarı toplamda 2.568.820 m2 olarak hesaplanmıştır. Sonuç olarak, Samsun il merkezinde kıyı bölgesinde dolgu yapılarak oldukça önemli miktarda değişimler olduğu görülmüştür. Kıyı alanlarındaki değişimler karadan denize veya denizden karaya meydana gelmektedir. Bu çalışmada kullanılan yöntem ile sadece kıyı alanlarında kazanılan alan değil, kıyı alanlarında kaybedilen alan değişimleri de hesaplanabilmektedir.

Monitoring the Coastal Changes in Samsun, Turkey

Öz

In this study, it is aimed to calculate the changes in the coastal area in Samsun city center by filling in the years. Existing aerial photographs and orthophotos of the study area were examined in detail. It has been studied using the ArcMap module of ArcGIS 10 software, using approximately periodic aerial photographs of 1935 and orthophotos of 2012. The amount of filling area in the coastal region of Samsun province was determined as 852.286 m2 between 1935-1972, 1.478.218 m2 between 1972-2006, 2.330.504 m2 between 1935-2006 and 238.316 m2 between 2006-2012. The amount of filling made in the province from 1935 to 2012 was calculated as 2,568,820 m2 in total. As a result, it has been observed that there are significant changes by filling the coastal area in Samsun city center. Changes in coastal areas occur from land to sea or from sea to land. With the method used in this study, not only the area gained in coastal areas, but also the changes in area lost in coastal areas can be calculated.
