Many impact assessment studies rely on hydrological and hydrodynamic (hydro) models.These models typically require a large set of parameters derived from different datasets hence manual setup can be time consuming hard to reproduce.HydroMT (Hydro Model Tools) is an open-source Python package that aims make the process building model instances analyzing results automated reproducible.The provides common interface data instances, workflows transform into based (hydrological) GIS statistical methods, various methods analyze results.The user describe full instance including its forcing in single configuration file sequence workflows, making reproducible, fast, modular.The has been designed with iterative, data-centered modeling mind.First-order schematizations built for any location world by leveraging open global datasets.These later improved updating input detailed local datasets.This iterative enables quickly get initial result then informed decisions about most relevant improvements and/or required collection kick-start discussions stakeholders.Furthermore, parameter maps or easily modified sensitivity analysis calibration support these robust practices.HydroMT successfully being used several software through plugin infrastructure allow specific functionality, such as readers writers formats, extended new software.Currently supported include distributed rainfall-runoff Wflow, flood SFINCS, water quality D-Water Quality D-Emissions Delft-FIAT.
