Exhaustive comparison of continental-scale hydrological models ensures better water management

Reed Maxwell was co-corresponding author of a Herculean effort to resolve the discrepancies between two models that capture hydrological processes for the entire United States so that scientists and policymakers can work from consistent, accurate data when managing the nation’s water budget. The project — which was the first model-to-model comparison of this scale — required a year of running supercomputer simulations and analyzing large data sets, as well as comparing the two models to almost 3,000 streamflow observations.
