The Object Modeling System (OMS) currently has essential core modules (taken from the SWAT, WEPP, RZWQM2, and the European J2K and J2K-S models) used for building and deploying the AgES-W watershed model. These core OMS-based modules will be further verified and new modules added (e.g., infiltration, tile drainage, and crop growth) to further improve AGES-W. OMS functionalities for model debugging, module connectivity, data provisioning, and cloud computing will be augmented as needed during this process. ARS scientists will evaluate the AgES-W model with experimental data from two to three Colorado and Midwest watersheds for water quantity and quality outcomes of land management and conservation practices. Based on the evaluation, the component modules will be upgraded or replaced with new improved modules. To facilitate the application of the improved AgES-W model, functionalities will be developed in OMS to access appropriate NRCS databases. Additional tools developed by ARS scientists for land unit delineation, parameterization, sensitivity/uncertainty analysis, output visualization, and scaling will also be fully implemented. The final package will be delivered to NRCS and ARS modelers for further evaluation and feedback for improvements.
