Groundwater resources are considered as the main and most important sources of drinking water,
agriculture and industry. It is necessary to study the quality change and decline in the balance of
these resources as a result of improper drawing, inappropriate temporal and spatial distribution of
water resources in Iran and low irrigation efficiency in agriculture, has made water the most
limiting factor of production in agriculture. In the present study, the fields under cultivation with
various crops were studied in terms of the effect of cultivating different plants on groundwater
resources in the lands of Moghan Agriculture, Industry and Animal Husbandry Company at
different time period according to the type of crop cultivated. For this purpose, spatial and
temporal modeling of the change process was carried out. The results showed that due to
successive cultivation and the use of crops that need a lot of water for cultivation, water in two wells in the region has become saline and the water level has decreased.
