The country's climate and water resources indicate a serious limitation of water resources, with more than two-thirds of the country's dry, semi-arid and desert areas being the main centers and population centers, including the country's metropolises, whose water supply resources rely on groundwater. It is located in less than a third of the country in other climates with humid and semi-humid climates. Therefore, the country's groundwater resources are currently in crisis due to over-harvesting due to the increase in unauthorized wells and overdrafts of authorized wells, along with the occurrence of consecutive droughts. Groundwater is one of the most important and main water resources in In addition to providing drinking water, agriculture and industry, the country plays an important role in the country's economic prosperity. In this study, the laws governing Iran's groundwater are examined and legal avenues are provided to rehabilitate canals, abandoned and barren wells, and so on.

Abstract
The main purpose of this paper is to evaluate and estimate the annual rainfall return period and provide the best statistical distribution. Therefore, the annual rainfall data of Karaj Synoptic Station has been used to estimate the rainfall with a return period of 200,100,50,25,5. Gift tests (x ̅), ...

The main purpose of this paper is to evaluate and estimate the annual rainfall return period and provide the best statistical distribution. Therefore, the annual rainfall data of Karaj Synoptic Station has been used to estimate the rainfall with a return period of 200,100,50,25,5. Gift tests (x ̅), Rss, K-S were used to use the best statistical distribution and finally smada software was used to analyze the selected distribution. The results of the study show that among the statistical distributions used in this study, the distribution of the lognormal is the most appropriate distribution.
