We conducted an evaluation focused on the cumulative average storage volume in aquifers over time (2004-2019), and the results presented in Figure \ref{560615}. As it was evident that all three aquifers experienced a negative trend in aquifer storage during the reviewed period, the trend analysis results of both the MK and TFPW-MK tests also confirmed this (Table \ref{974045}). All three aquifers exhibit a statistically significant downward trend in aquifer water volume at the 95% confidence level, suggesting that the overall water storage in these aquifers was decreasing over time. The magnitude of the downward trend in aquifer storage, with a total of around 450 million cubic meters, was most significant in the Damaneh-Daran aquifer, which covers an area of roughly half of Buin Miandasht, suggests that this aquifer experienced the most severe depletion of groundwater resources. Meanwhile, the Buin Miandasht and Chehel Khaneh aquifers had fluctuations in aquifer storage ranging from 8.7 to -30.2 and -0.6 to -2.85 million cubic meters, respectively.
