Paper Title
Determining Hydrological Characteristics of a Stream by Using GIS Methods

Abstract
To protect river basins, it is necessary to know about the river and the basin. Geographical Information System (GIS) software are used to determine river basin parameters. In the study; hydrological properties of Malatya-Derme sub- basin were investigated. Derme sub-basin has contains drinking water for Malatya province, irrigation projects and hydroelectric power plants. ArcGIS software was used in the study. Hydrological properties of Derme sub-basin were determined and commented. Keywords- Derme sub-basin, ArcGIS, Hydrological characteristics, Basin shape.
