As part of the National Water Budget Project, our objective is to quantify how well observed trends are simulated.

We propose to do the evaluation using daily values from a national subset of gaged basins (Reference gages selected from GAGES-II (about 2000) that have about 80% completeness for the period 1980-2011). In addition to trends, we plan to do some basic attribution work examining geographic variability of trends and by analyzing selected results as a function of basin characteristics. This attribution 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.
