Model Library

Model library serves as a comprehensive reference guide for various watershed and waterbody simulation models. It provides detailed descriptions of each model’s type, developers, capabilities, limitations, computational requirements, and data inputs and outputs. The aim is to assist researchers, policymakers, and practitioners in selecting the most suitable modeling tools for their specific application. Each model entry includes links to download resources if it is open-source, relevant references, and examples of practical applications to further support users in making informed decisions. For more details see Model Library.
