Jiroft Plain in the south of Kerman province with dry and semi-arid climatic conditions, relies on underground water resources, the purpose of this research is to investigate the quantity and quality of underground water in a part of Jiroft Plain, to identify and evaluate the consequences of the drop-in water level and to propose. All meteorological, hydrological, water, geological, and geographical information about the region were collected and analyzed. Using the information of quantitative and qualitative changes of underground water in the last few years, and assuming the continuation of the current process of feeding and emptying the aquifer, the situation of the next 10 years was also predicted. According to the calculations, the level of underground water in the plain has been decreasing in the past years, so from the water year 82-83 to 92-93 with an annual average of 0.5 meters, it has dropped to 64.5 meters in the period. research results showed that the indiscriminate extraction of the plain's underground water table has resulted in consequences such as changing the quality of the underground water, and increasing the vulnerability of the plain to drought and land subsidence. They control water harvesting, determine the waters of the agricultural sector, change the cultivation pattern, and prepare the optimal cultivation pattern according to the land and climate conditions. The region, stating the problems and increasing the users' knowledge, is one of the findings of this project in management solutions.
