Determination of the River Basin Boundaries with the Help of GIS in Turkey

The aim of the study is to establish an approach that the basin boundaries can be provided faster than classical methods. Today, the digital elevation model (DEM) can be formed by different methods. One of these methods is the creation of the digital elevation model by remote sensing method. Remote sensing model was used in this study. It is time consuming and challenging to create a digital elevation model using classical methods. Moreover, Turkey to create up to cover a large area digital elevation model, due to the size of the area can cause a lot of mistakes. The created model may not represent the surface correctly. Digital elevation models obtained by remote sensing method have higher accuracy and give more accurate results in analysis. Digital elevation model obtained by remote sensing. In this study, watershed boundaries in Turkey have been identified using the geographic information system. It has been shown that it is much easier and quicker to identify the basin boundaries with this method.
