Both weighted Euclidian distance (ED) and Mahalanobis distance (MD) were tested to select
analogue situations with respect to catchment-scale predictors (methods 2 to 4):
ED(u) =

where s j is the standard deviation of jth variable o j over the sample set.
The Mahalanobis distance is an Euclidian distance which considers
