In order to closely monitor the state of groundwater resources and their optimal management, it is necessary to assess the fluctuations in groundwater levels, and then the influence of water quality. The current research was carried out with the aim of studying the fluctuations of groundwater level on its quality in Zarand watershed in Kerman province. For this purpose, the properties of 14 qualitative parameters of groundwater are studied, including the concentration of Na, K, Ca and Mg, the concentration of Cl-, So4, Co3-2 and HCO3 anions, SAR, sodium percentage, TH, TDS, pH and Ec for the area studied were assessed in the period from 2002-2003 to 2018-2019. Since the quality of groundwater depends on its quantity, changes in the quality parameters of water depending on the level of the aquifer were examined in the watershed. According to the results, there is a significant linear relationship between EC and TDS with R2 above 0.9. Monitoring salinity changes over time showed that the trend of salinity changes in this area increased over the studied period. To study the relationship between the qualitative parameters and the level of the groundwater table, the chemograph chart showed that the aquifer experienced a drop of 19.32 m, resulting in an increase in salinity of 229.37 µS/cm. The study of salinity and water level changes per year also shows a negative relationship (0.007) between the two parameters and is not acceptable from a statistical point of view. The results of this study can provide important information for the development of water management strategies and ensure sustainable management and safe use of water.
