CCDB - catchment characteristics data base Germany

This data set provides geoinformation data, natural and anthropogenic characteristics of 1386 catchments across Germany as part of the QUADICA data set.
The attributes include information on topography, land cover, lithology, soils, climate, hydrology, population density and nutrient sources and heterogeneity.
The calculated catchment attributes base on various publicly available and published resources referenced in the metadata of this repository.
The data set from this repository combines the two existing CCDB repositories for the German catchments (Ebeling, 2021: https://doi.org/10.4211/hs.0fc1b5b1be4a475aacfd9545e72e6839; Ebeling & Dupas, 2021: https://doi.org/10.4211/hs.c7d4df3ba74647f0aa83ae92be2e294b).
A corresponding paper "Water quality, discharge and catchment attributes for large-sample studies in Germany - QUADICA" by Ebeling et al. describing the QUADICA data set in detail will be made available in the Journal Earth System Science Data (https://www.earth-system-science-data.net/).

This repository includes:

1.) Data table with catchment attributes
2.) Metadata with the description of each catchment attribute and references to original publications and data resources.
3.) Shapefile with delineated catchment polygons
4.) Shapefile with stations.

Water quality and quantity data, as well as meteorological and N surplus time series are available in the "QUADICA - water quality, discharge and catchment attributes for large-sample studies in Germany" repository (https://doi.org/10.4211/hs.26e8238f0be14fa1a49641cd8a455e29). All repositories use the same unique identifier OBJECTID for each water quality station.

Note: the stations do not always fall within the delineated catchments as the catchment outlets were adapted according the stream network and the topographic flow accumulation grid.
