An online tool and open database for curve number (CN) data retrieval in Europe used for estimating runoff from precipitation events
摘要
The SCS-CN approach constitutes a straightforward, reliable, and consistent approach for estimating runoff from precipitation events. In the present work we introduce the CN-panEU, an innovative online tool (http://cn-paneu.survey.ntua.gr/main.html) for CN data collection throughout European countries. The pan-European CN gridded dataset was developed based on the Harmonized World Soil Database (HWSD) and the land use/land cover data from the Corine Land Cover (2018). The CN was estimated using ArcMap 10.5.1, based on the hydrologic soil group category, the Corine land cover and the tabulated CN values reported by SCS (
