Antalya Batimetri Boğaçay kıyı çizgisi değişimi Konyaaltı uydu görüntüsü
While Konyaaltı (Antalya) Beach was formed by the sediment supply of the
Boğaçay and Sarısu streams, Boğaçay remained the only sediment source for the eastern
section after the port construction. Due to the change in the volume of
material carried by Boğaçay and longshore drift along the beach, time-dependent
shore line changes occurred. As an artificial lagoon was built on Boğaçay, accordingly,
the sediment regime of the stream will change, sedimentation will start on the artificial
lagoon bottom, and shore line will be changed on the beach, it is aimed to investigate
the time-related change on the shore. The use of satellite images is becoming widespread
in generating geomorphological information due to the large spatial data of
large areas, the images being numerical data and the ability to be processed directly.
Images enhanced with image processing techniques are used for measurement and classification
purposes. In this study, high resolution satellite images were used to determine
the temporal variation of the shore line and the base morphology of the artificial
lagoon. Image processing, analysis and result display operations were carried out
in MatLab environment. As a result of the analysis; It is concluded that there
is a severe coastal regression in the western part of Konyaaltı Beach, and this
regression will continue in the future as the region is not fed with sediment.
It has been observed that there is a change in the bottom morphology of Boğaçay
artificial lagoon, a 163 cm relief is formed at the base, and in some regions there
is a mud sedimentation up to 120 cm, and reed type plants start to grow in
places. It has been understood that coarse-grained material has not yet been transported
from the stream to the lagoon, the material that deposited is mud and the material
that will feed the beach does not reach the beach. It is revealed that there is
a significant coastline regression in Gürsu beach, although the beach here is
fed by solid material with longshore drift.
