Conclusion
This paper introduced a hierarchical organization of hydrological
processes, derived from literature review of journal articles describing
experimental watersheds, perceptual models and runoff generation
processes. The taxonomy includes over 120 named processes, which are
recorded alongside their functional type (e.g. storage, flux),
alternative names, and a unique identifier. Processes often had multiple
alternative names, which can hinder extraction and sharing of
hydrological information. We recommend that authors of journal articles
use consistent terms for processes throughout, and consider a separate
section with succinct process inference information. The taxonomy can
promote hydrological information sharing and synthesis by providing a
method to label and search process knowledge.
