AB: Regionalization, which aims to estimate the model parameters for the ungauged basins from the model parameters for the gauged basins within the same region, provides a method to predict the streamflow in the ungauged basins. However, most of regionalization researches have to calibrate model parameters and derive basin descriptors using two isolated software tools: hydrological modelling software and GIS. In order to facilitate model regionalization research, an ArcGIS extension: ArcRegionalization is developed with C# language to integrate basin descriptor derivation and hydrological models. ArcRegionalization not only provides basin descriptors derivation methods, widely used hydrological models, and regionalization methods, but also provides the interfaces to incorporate new basin descriptors, new hydrological models, and new regionalization methods. Finally, a case study of model regionalization in Oak Ridges Moraine area, southern Ontario, Canada is used to demonstrate the functions of ArcRegionalization.
