The topic of rural–civil migration is always oblivious. This research is a case study of situations of rural immigrants codified in Mamasani city. ‌The structural attitude attention toward elements and and agents of rural immigrants and limitation of immigrant in migration site ‌is ‌the ‌goal ‌and‌ dominant ‌view point. . The research method is based on functional goals and has case descriptive analytic nature. The study consisting Mamasani city acquiring information is based on GIS and SPSS software through ANOVA test and pearson statistical correlation. Results shows that Mamasani faces high range of migration during theses four decades most of which impactsan was during 1355 -1365 and 1365 -1375 causing negative impactsan rural and urban environement. also the most important rural problem of this city is shortage of income and lack of instructional services.

Seeking new sources of groundwater as a source of drinking water in the world due to increasing demand for this vital world is necessary and inevitable.In recent years due to excessive interpretations of these resources the plains are dropping in a way that the depletion of aquifer is more than feeding it. And it causes a negative balance and positive feedback and finally leads to collapse of system. Factors such as population growth, the need for food, the need to improve health and social welfare, industrial development and the protection of ecosystems is increasing water demands every day. That's why the choosing an appropriate and effective, yet professional approach, in order to solve problems faced by water resource management, is necessary. Identify underground water  resources, identify areas with high potential and improving the removal of these resources are the most important goals. The study area is the catchment area of NURABAD MAMSANI of about 756 square kilometers is located in Fars Province in the northwestern part. In this study, the Shannon entropy were studied using 9 raster layer of the area to locate potential sources of underground water basin. And the results of the study showed that the lowest sensitive areas located in the Central Plains that it will take approximately 64% of the areas. And more sensitivity is related to the southern plain which is equal to 2% that is covered 16 kilometers of the area. Results of Shannon entropy model using (ROC) curve showed that the amount of AUC is 85% which is a high and acceptable amount.
