Collector gatherers were the most abundant functional feeding

Although different hydraulic conductivity values were introduced into the model during the calibration process, a taxon value of 20 m/day (which best represents the natural conditions) was assumed to be constant for the entire aquifer system. The calibrated groundwater model shows a mean absolute error of 4.83 m, a standard error, estimated in 0.34 m, and a model efficiency of 0.996 between 32 observed and simulated at groundwater levels (Fig. 4).
