Aggregated total Sobol' sensitivity indexes
The following map will give you an overview on the
sensitivity of eight hydrologic processes and three input
corrections across all watersheds in North America
analyses. The processes considered here are infiltration,
quickflow, evaporation, baseflow, snow balance, convolution
of surface runoff, convolution of delayed runoff, and
percolation. The three input corrections are potential melt,
rain-snow partitioning, and precipitation
correction.
The indexes displayed are the
variance-weighted time-aggregated total Sobol' sensitivity
indexes regarding streamflow simulated using the blended Raven
model based on HMETS (panel C in the figure below).
The simulation period is 1989 to 2010
while the first two years are discarded as warm-up
period. The weights for each time step of the streamflow
time series are derived using the variance of all
simulations at the given time step.
