Abstract:
HyperHydro (http://www.hyperhydro.org/) is an open network of scientists with the objective of simulating large-scale terrestrial hydrology and water resources at hyper-resolution (Bierkens et al., 2014, DOI: 10.1002/hyp.10391). Within the HyperHydro network, a modeling workshop was held at Utrecht University, the Netherlands, on 9-12 June 2015. The goal of the workshop was to start the HyperHydro (H^2) experiment for comparing different large-scale hydrological models, at different spatial resolutions, from 50 km to 1 km. Model simulation results (e.g. discharge, soil moisture, evaporation, snow, groundwater depth, etc.) are evaluated to available observation data and compared across various models and resolutions.

In AGU 2015, we would like to present the results of this inter-comparison experiment. During the workshop in Utrecht, the models compared were CLM, LISFLOOD, mHM, ParFlow-CLM, PCR-GLOBWB, TerrSysMP, VIC and WaterGAP. We invite participation from the hydrology community on this experiment. As test-beds, we focus on two river basins: San Joaquin (~82000 km2) and Rhine (~185000 km2). In the near future, we will escalate this experiment to the CONUS and CORDEX-EU domains.

The picture below was taken during the workshop in Utrecht (9-12 June 2015).
