EoCoE: High Resolution River Discharge Modeling for Hydropower Energy Applications

In the scope of EoCoE, a continental scale high resolution hydrologic modeling system for the investigation of river discharge in the European region is developed at 3Km resolution using hydrological models, ParFlow and Common Land Model (CLM). ParFlow is a massively parallel three dimensional watershed model which simulates fully coupled surface and subsurface flow; suitable for large scale problems, where CLM simulates discharge predictions in combinations with a river routing algorithm. For calibration and validation of model outputs, comparisons of observed and modeled discharge data for a given geographic region and time frame is made to evaluate the accuracy and suitability of each model. Through these modeling systems, it is now possible to assess modeled time series data using visualization tools and post-processing analysis chains developed in collaboration with EoCoE HPC experts. Development of these additional features and tools has contributed greatly to the EoCoE impact modeling efforts to assess river discharge information for hydropower energy applications.
