Watershed morphometric characteristics are based on the terrain processing that must be done for each different watershed. There is no application that provides basin morphometric characteristics, basin borders, and streams in the basin on a global scale, so the development of a new application has become a necessity.In this research, an online Google Earth Engine (GEE) application has been developed that determines the morphometric characteristics of any watershed on a global scale using digital elevation models, basin bound-aries, and river stream data.The Meric basin was selected for testing the application. The results of the application were validated by comparing them to ArcGIS. The findings demonstrate that, in the absence of GIS software or data, GEE may be used to determine basin morphometric characteristics on a worldwide scale.en10.1016/j.envsoft.2023.105640info:eu-repo/semantics/closedAccessMorphological characteristicsHydrologyGISGEEWatershedBasinBasinCatchmentToolArticle162Q1WOS:0009628036000012-s2.0-85148095380Q1
