topic problems in River Merging using ArcGIS 10.1 via the Hec-GeoHMS 10.1 extension in Data Management Questions https://community.esri.com/t5/data-management-questions/problems-in-river-merging-using-arcgis-10-1-via/m-p/335736#M19086 <HTML><HEAD></HEAD><BODY><P>Hello! I use the Hec-GeoHMS 10.1 extension in ArcGIS 10.1. After merging 65 subbasins into one basin, I'm trying to river merge all individual streams unsuccessfully. The message from the above action is: disconnected rivers or rivers meeting at confluence can not be merged. I notice that all individual streams are meeting at a confluence. I would like to ask if I'm doing something wrong or if there is an alternative methodology in order to merge all rivers in one. Thank you in advance.</P></BODY></HTML> Thu, 13 Jun 2019 09:12:13 GMT sofiasarchani 2019-06-13T09:12:13Z problems in River Merging using ArcGIS 10.1 via the Hec-GeoHMS 10.1 extension https://community.esri.com/t5/data-management-questions/problems-in-river-merging-using-arcgis-10-1-via/m-p/335736#M19086 <HTML><HEAD></HEAD><BODY><P>Hello!
