In-Depth Information
•
Direct estimation of model parameters based on soil, land use and other information (as used in defining
land surface parameterisations of atmospheric circulation models) has not been shown to provide
accurate simulations of ungauged basins. Where information is available for local conditioning of
default parameter estimates, better results are usually obtained.
•
One of the most effective ways of constraining prediction uncertainties for an ungauged basin might
be to make a few discharge measurements or use a few measurements to constrain a rating curve for
a level sensor. Other types of “soft” information might also be used in the conditioning process.
