How to determine the regional threshold values (T) of Na, Mg, Cl and SO4 in the groundwater of study area while calculating seawater mixing index ?

06 September 2017 1 7K Report

T represents the calculated regional threshold values of selected ions in groundwater samples, which can be estimated from the interpretation of cumulative probability curves.

Can you please explain how to draw cumulative probability curves for the concentrations of Cl, Na, Mg, and SO4 in groundwaters and find infelction point?

Bayan Hussien

the link below may help in drawing cumulative probability curves. Gumbel method, thanks
