Abstract
This repository provides metrics of water quality and quantity of 1386 German catchments based on time series of the
"WQQDB - water quality and quantity data base Germany" (Musolff, 2020) subsetting years from 2000 to 2015.
The data from this repository were created for Ebeling et al. (2021). Selection criteria and results are presented more in depth therein.
Natural and anthropogenic catchment characteristics are provided in another, linked repository "CCDB - catchment characteristics data base Germany" (https://doi.org/10.4211/hs.0fc1b5b1be4a475aacfd9545e72e6839). Both repositories use the same unique identifier OBJECTID for each water quality station.
This repository includes:
1.) Data table with unique identifier (OBJECTID), station name and calculated metrics of water quality dynamics for nitrate (NO3-N), phosphate (PO4-P) and total organic carbon (TOC). The metrics are mean concentrations, the slope b of the concentration (C) - discharge (Q) regression in logspace, the corresponding R2, and the ratio of the coefficients of variation CVC/CVQ. The data table also includes a flag "indep" for the independence of catchments (max. 20% area overlap with each of its subcatchments) including criteria (e.g. priority of C-Q catchments) as described in Ebeling et al. (2021). Accordingly 787 catchments are considered as independent.
2.) Readme file providing information on provided data.
