As part of the National Water Budget Project, our objective is to quantify how well observed trends are simulated.
We are evaluating multiple statistical models and one process-based model, in terms of how well the models reproduce measured streamflow at USGS gages across the United States. This includes how accurately models reproduce low through high flows for long periods of record and how well they reproduce trends over time. In addition, we are analyzing the geographic variability of results and how reservoir storage and agricultural irrigation affect modeled flows. This work will help point to basins with flow characteristics that are not being modeled well, and those that are. This may indicate how well different processes are being modeled and point to priorities for model improvement.
