Analysis of spatial and temporal changes at surface area of Homa Lagoon (İzmir Bay, Aegean Sea) using remote sensing techniques

A lagoon is a shallow body of water separated from a larger body of water by barrier islands or reefs. Homa Lagoon wetland in İzmir, Turkey, it was take to the protection status in 1982 and group "A" is in wetland status. Homa Lagoon in Gediz Delta area is the protection and reproduction area of birds and the RAMSAR region since 1998 to ensure the conservation of biological reserves and sustainable management. In this thesis, it is aim to determine the current state of the surface area of the lake and to determine the changes occurring in the surface area of the lake from past years to the day by using remote sensing methods. Eight selected Landsat 5 TM and Landsat 8 OLI images were use of between to 1984-2017. These images were correct and made to fit the study by making field crossings. The images were then classify and changes in the surface of the lake were analysed with the normalized water index (NDWI). In the direction of the analyses, it is seen that the Kırdeniz Lagoon feeding the Homa Lagoon completely disappeared and the Homa Lagoon was experiencing a relatively less shrinkage in line with the conservation work done and it has been seen that the mouth opening called the Taş channel has grown in the region.
