Abstract
Hydrological modeling increasingly relies on integrating heterogeneous models to represent complex natural systems, motivating approaches that improve modularity and interoperability. This paper presents the refactoring and componentization of a hydrologic model and its major routines using the Basic Model Interface (BMI) to enable integration within model-agnostic frameworks such as the Next Generation Water Resources Modeling Framework (NextGen). As a case study, Python BMI components were developed for both the full Hydrologiska Byråns Vattenbalansavdelning (HBV) model, and its individual routines yielding standardized importable and composable model components. These components were integrated within a multi-model, component-based NextGen formulation that enables data exchange and comparison with other NextGen components. This work demonstrates the benefits of using BMI to standardize hydrologic models, promoting reusability, community-driven development, and interoperability across hydrologic modeling applications, while providing a practical roadmap for converting hydrologic models into BMI model components and integration within BMI-compliant frameworks such as NextGen.
