Setting expectations for hydrologic model performance with an ensemble of simple benchmarks

Example of benchmark inputs and results for a snow-dominated basin, subset to a 4-year period on either side of the calculation (left) and evaluation (right) divide (dotted red line). KGE scores in legends are calculated for the evaluation period. (a) Observed streamflow, precipitation and a ‘rain plus melt’ flux (RPM) derived from precipitation and temperature. RPM is used to define the benchmarks shown in c and d. (b) Flow-only benchmarks. The straight light green line is the traditional (NSE = 0; KGE = 1-√2) mean flow benchmark. (c) Rainfall-runoff ratio benchmarks. A single rainfall-runoff ratio is derived from the data in the calculation period and used to scale annual and monthly RPM sums into flow benchmarks. (d) Simple models that represent catchment function.

期刊介绍： Hydrological Processes is an international journal that publishes original scientific papers advancing understanding of the mechanisms underlying the movement and storage of water in the environment, and the interaction of water with geological, biogeochemical, atmospheric and ecological systems. Not all papers related to water resources are appropriate for submission to this journal; rather we seek papers that clearly articulate the role(s) of hydrological processes.
