Abstract

The study of the groundwater resources and their properties are very important due to the vast desert areas and arid conditions. Given the current situation in Iran, the water supply is one of the most important territorial and environmental problems. In this study, groundwater resources were surveyed and mapped in Yazd Province and their properties were modeled to determine their effectiveness for grazing and agricultural activities. The main objective of this study was to develop and establish groundwater geoinformatics and cartographic monitoring of the meteorological data and groundwater formation. Also, the climatic characteristics were evaluated as determinants parameters of groundwater flow to measure its parameters variations. The thematic charts and geoinformatics maps were provided. Profile software was used for modeling microclimate and groundwater flow’s parameters, like groundwater level and moisture transfer for several decades. Priznak model was used for comparison and multi-parameter analysis of specified profiles and their classification. Finally, different regions of Yazd Province were mapped and classified with different degrees of possibility for grazing and agricultural activities. Results showed that groundwater levels in the study territory are at depths ranging from 40 to 145 m. According to the results, it was observed that the changes in groundwater level and microclimate can be used to evaluate the land capability for grazing and agricultural activities.
