(Left panel) Total aquifer volume change for three one year intervals from October of the preceding year to October of that year. The total volume change is obtained by summing the volume changes of every grid block in the model. (Right panel) Difference between cumulative changes for the water years 2017 and 2018, and those of the water year 2016. That is, the volume changes during 2016 are subtracted from those of 2017 and 2018 in order to derive these two curves.
