A groundwater security model based on hydraulic turnover times and flow compartments.

ABSTRACT: Starting with a log-linear relationship between groundwater discharge per unit drainage area (Q/A _b), hydraulic turnover time (t) and aquifer mobile storage (z), this study builds a groundwater security method at catchment scale. The method embeds previously published approaches to calculate Q/A _b, t and z, and relies solely on stream flow discharges and watershed areas. The ability to build a method on a couple of variables is remarkable. The method recasts the calculated variables as aquifer security indicators (S _Q, S _t and S _z), relating S _Q with yield capacity, S _t with self-depuration capacity and S _z
