• River Gauging Station Data Quality Classification (GSDQ). A UK based method for assessing the quality of ratings curves and associated data. In depth and good material for style of metadata required for making detailed assesments of quality (this could be formed as a use case).

Uncertainty papers

Here are citations to a couple of recent papers on hydrometric uncertainty. Ultimately, the primary use-case for sharing of ratings gaugings and cross sections is to mitigate for the lack in objective quantification of uncertainty in discharge timeseries. Sophisticated operational and scientific users of discharge data need to inspect how robust the derivation of discharge from stage is in order to establish the confidence with which critical decisions or hypothesis tests can be based. This understanding how the information is of use is germane to design and development of the standard.
