Given that the water balance implies Qmean = x AREAy
where x and y are coefficients,
Vmean = a AREAb where a and b are constant coefficients
Wmean = c AREAd where c and d are constant coefficients
Dmean = e AREAf where e and f are constant coefficients
a AREAb * c AREAd * e AREAf = a*c*e *AREA b+d+f = Q
and therefore the coeffs are
