TI  - OPPORTUNITIES PROVIDED BY REMOTE SENSING DATA FOR WATERSHED MANAGEMENT: EXAMPLE OF KONYA CLOSED BASIN
AB  - Remote sensing data provides great opportunities in various steps of watershed management like characterization of watersheds that bear dynamic structure with large land, monitoring the physical variations within the basin, and conducting various scenario analysesto detect the response of the basin. The high resolution capacity of today’s satellite images enables the production of land use/cover data of abasin in shorter period of time. In this study, it is aimed to demonstrate various aspects of remote sensing technology to be used in watershed management studies.For that purpose, MODIS, LandsatandSentinelsatellite datawithdifferent spatial resolutions were used to monitor the surface water bodies in Konya Closed Basin(KCB)of Turkey. In addition, high spatial Worldview-3 satellite data were used to extract detailed information about Akgol Wetlandlocated in KCB.A methodology was developed on the utilization of remote sensing technology consisting of 3 main groups; field surveys, satellite images and ancillary data.In the study, 5 different spectral indiceswereapplied to Sentinel2data to determine the areas of surface water bodies.Moreover, SupportVector Machine(SVM)method was applied to Worldview-3 satellite image toclassify Akgol Wetland and its vicinity.The importance of establishing watershed information system together with a database reflecting the characteristics of watersheds was underlined. Various examples were given from KCB that is known as the largest closed basin of the country with a surface area of 5.426.480 ha. The basin owns 17 water bodies out of which 2 of them are RAMSAR sites. Within the scope of the study, information obtained from optical and synthetic aperture radar (SAR)satellite images in the basin were discussed.More accurate results were achieved by Sentinel 2than MODIS and Landsat data.In addition, detailed information about the wetland wereextracted by means of Worldview-3 data and water bodies weremonitored in all weather conditions viaSentinel 1 SAR data.
