Classification of River Catchments in the Contiguous United States: Processed Dataset, Similarity Patterns, and Resulting Classes

This dataset serves as supplementary information for the paper by Ciulla F. and Varadharajan C. A Network Approach for Multiscale Catchment Classification using Traits (see reference 1). It contains environmental and physical catchment traits, such as temperatures, precipitation, land use and human interference, from 9067 sites across the contiguous United States (CONUS). The purpose of this dataset is to provide information for a better trait-based categorization of river catchments in the CONUS using networks as an analytical tool. The traits variables generally match the ones present in the GAGES-II dataset and the preprocessing steps are described in the Methods section (csv file). Additionally we include the topologies (nodes, edges and clusters, also referred as classes) of the catchment network and traits network generated by said dataset (csv and json files). A series of tables support the information carried by the network providing more detailed descriptions of cluster components (pdf file). A summary of all the plots of clusters of catchments with at least 50 nodes is provided (pdf file). The characteristic traits for each cluster of catchments is presented as z-score (csv file). The link to the hydrological behavior of clusters of catchments is displayed by boxplots, each describing a particular river discharge index (pdf file). Both csv and json files can be read by common text editors but the data contained into them can be better handled using programming languages like python and database oriented libraries like pandas. Pdf files can be read by any pdf reader software.
