Description

Aggregates the values of the 9 sub-objectives at the second-highest aggregation level of the hydrology module of the Swiss River Assessment Program MSK (2011).

Usage

msk.hydrol.2011.aggregate(u,
                          par = NA)

Arguments

u

Numerical vector of length 9 containing the values that quantify the degree of fulfillment of the 9 sub-objettives.

par

Argument added for consistency with the other aggregation procedures. No parameters are needed.

Value

The function returns the aggregated value.
