Description: This project is part of Indiana University's Grand Challenges Prepared for Environmental Change project. For this project, we are building a computer-based watershed model of the Wabash River Basin. This model will be used to investigate climate change impacts on water resources in Indiana. Along with the hydrological modeling, we are developing a science gateway that will include interactive plots and maps to make the results of the hydrological model results available to other researchers and to the public. The requested XSEDE computing resources will be used to complete post-processing of the model results and to provide the Science Gateway services.
