Digital Hydroconnectivity of Reservoirs and Streamgages across the coterminous United States using RICON algorithm

This dataset presents the digital hydroconnectivity between streamgages and reservoirs as a concise edge list for the coterminous United States (CONUS) using the River and Infrastructure Connectivity Network (RICON) algorithm. The dependency between streamgages and reservoirs across CONUS provides (1) a complete list of edges for the unidirectional network connecting streamgages, reservoirs, and NHDPlusflowline features across different watershed regions, and (2) attributes of all nodes (reservoirs and streamgages), including their geospatial locations, unique identifiers, immediately upstream and downstream nodes, etc. The CONUS RICON data archive available at Hydroshare contains the dataset tables in comma-separated values (CSV) format. The combined information of all nodes and NHDflowline information are provided as ".rds" files, NHDPlusv2 attributes used for each drainage are provided in ".RData" format. For each drainage area, final output hydroconnectivity presented as individual edge lists are saved as 'Edge_List.csv' in each subfolder. All the codes for data development and additional vignettes are available on Github.
