Özet:

 Watershed modeling plays a crucial role in hydrological analyses, primarily involving the essential task of delineating the catchment area into watershed and sub-watershed components for convenient characterization. This study specifically focuses on the delineation of watersheds using ArcHydro tools in conjunction with geospatial technologies. Arc-Hydro, developed as an extension to the ArcGIS software, functions as a model specifically designed for constructing hydrologic information systems. It integrates geospatial and temporal water resources data to support hydrologic modeling and analysis. ArcHydro offers manual extraction options, enhancing efficiency in extensive watershed studies and facilitating dataset management in modeling efforts. However, it is imperative to adhere to the correct sequence, as errors in using any tool within the sequence can impede the successful execution of the entire Arc-Hydro model, thereby hindering the intended delineation of watersheds. This challenge is particularly noteworthy for beginner who may be prone to such mistakes. In our current study, we utilized a high-resolution 12.5 m Digital Elevation Model DEM of the Sudurpashchim province to delineate the catchment area and drainage network of the Budhiganga waterbody. The use of this tool ensures that users can achieve the desired results effectively in a single click.
