OpenWQ v.1: A multi-chemistry modelling framework to enable flexible, transparent, interoperable, and reproducible water quality simulations in existing hydro-models
Abstract. This work advances the cross-model deployment of ecological and biogeochemical simulation capabilities in existing process-based hydro-modeling tools, which we term "Open Water Quality" (OpenWQ). We detail aspects of OpenWQ's architecture that enable its plug-in type incorporation into existing models, along with its innovative aspects that enable biogeochemistry lab-like capabilities. OpenWQ's innovative aspects allow modelers to define the pollution problem(s) of interest, the appropriate complexity of the biogeochemistry routines, test different modeling hypotheses, and deploy them across different hydro-models. A coupling recipe for linking OpenWQ to existing hydro-models is described and demonstrated on two models with different model structures, SUMMA and CRHM. Such model integration helps establish a more formal (and direct) exchange of innovation between hydrological and biogeochemical-water quality modeling communities. Example applications of different pollution studies enabled by OpenWQ are provided with robust numerical verification.
