Technical Abstract: To assess anthropogenic impacts on agro-ecosystems a comprehensive modeling capabilities are required accounting complex processes at surface and subsurface domains. To address this need, the SWAT and MODFLOW models were integrated to better represent surface-subsurface water interaction. A modeling framework was developed due to differences in models spatial discretization and representation, and a new application implemented as a project manager, builder, and model performance evaluator. The model was evaluated in the Fort Cobb Reservoir experimental watershed, Oklahoma. Results from streamflow and groundwater levels showed that there was a general agreement with observations trends. However, the model was not able to properly represent low streamflow under dry conditions and aquifer depletions rates due to deficiencies in spatial parameterization and simulated well extractions volumes, which frames our future investigation. This modeling framework is expected to improve simulation at the watershed scale, thus providing a platform for more detailed transport phenomena simulations.
