According to written sources, the city of Beymand was one of the cities of Kerman province in the early centuries of the Islamic era. Beymand was considered to be one of the more important cities of this era due to its location on the important communication route from Shiraz to Sirjan. By studying the written resources and archaeological findings, we can determine that the  Beymand city of the early Islamic centuries is in the same area as Bagh-Bamid. Studying the pottery of this site between the 1st to 13th centuries AD to make a typology and chronology of these findings is the objective of the current research and it seeks to answer the following questions:  what types of pottery were included in the Pottery findings in this site ? What period does the pottery belong to in terms of chronology? By comparing the pottery findings, can we conclude what the regional and transregional interactions with other neighboring and remote sites were? The research was conducted by doing fieldwork and using library methods with a descriptive-analytical and comparative approach. For establishing the dating and typology of the pottery findings obtained from the study of this area, first, these findings were classified into different groups based on their similarity in form, paste, and decoration. Then, their relative dating was obtained by comparative comparison with similar samples obtained from excavations and surveys of other areas. The typological comparison of the pottery samples of the Bagh-Bamid area does a good job of highlighting the similarity between the different types of pottery with the pottery of nearby areas such as the old city of Sirjan and more distant ones such as the ancient city of Jiroft, Narmashir and so on.

Sirjan plain in southeastern Iran has a good communication position. There are many settlements from different eras in this plain, including Shah Firooz Tepe. Different opinions have been expressed about the chronology of the building called Shah Firooz, located on top of this tepe. During the archeological study carried out in the above site in 2018, several pottery pieces were sampled and studied.The purpose of this study is to chronology and typology of pottery obtained from the Shah Firooz site and seeks to answer these questions:Pottery findings in this site include which types of pottery?What period does pottery belong to in terms of chronology?According to the comparison of pottery findings, what are regional and transregional interactions with other neighboring and remote sites?This is a field and library research with a descriptive-analytical and comparative approach. The results of the studies showed that the pottery findings of this site included unglazed and glazed pottery, which are divided into normal, grooved, patterned unglazed, monochrom glazed (plain and painted), and multicolored glazed (Sgraffito , blue and white, Splashed Glazed, and Slip Painted). According to the comparisons, these findings can be dated to the Sassanid era, the early Islamic and Safavid centuries. The homogeneity of potteries with the sites of the ancient city of Jiroft, Ghubayra, Rayen, Narmashir, and Sirjan plain, in addition to the using regional pottery patterns and traditions, indicates the trans-regional interactions of this site with the culture of the west, southwest, northeast of Iran, and the edge of the Persian Gulf.

Watermills are considered valuable treasures of Iranian indigenous and cultural knowledge. Due to the climatic conditions of this land, the people of the past have tried to make maximum use of water energy by building water structures. Therefore, watermills that have used the knowledge of water engineering, mechanics, and architecture, have been used in different parts of Iran since ancient times. One of these water structures is Qutbiyeh Mill in Sirjan city, identified and studied during archaeological field activities in 2019. The purpose of this article is to introduce and study the Qotbiyeh water mill in Sirjan plain to gain a proper understanding of its performance and architecture analysis. The questions of this research are as follows: Qutbiyeh water mill belongs to which type of water mills in Iran? What were the components and the architectural structure of this mill? The present study was conducted by descriptive-analytical method, and its data were collected based on field studies and literature. The results showed that the Sirjan Qotbiyeh water mill was a furnace watermill, working with the water of the Qotbiyeh qanat, and its architectural structure included a complete set of different main and side spaces surrounded by a circular defensive wall.

. Land use prediction models are essential for planning sustainable land use. This is especially needed in developing countries where activities such as deforestation, development of agricultural lands, and degradation which intensifies the phenomenon of desertification. Since land use changes occur on a large scale over time, the use of remote sensing science is essential in investigating this phenomenon. Using data such as multi-time and large coverage, this data can be used to prepare land use maps and survey them in different time periods at the lowest cost and in a short time, and from their ratio, changes can be predicted for the future. The results show that the region has a sensitive ecosystem, land use change is happening rapidly. Therefore, if the current strategy of land use in this region continues without consideration for sustainable development, severe land degradation and desertification of the region in the future is inevitable.In this research, we studied trend of land use change in Sirjan plain that located in the west of Kerman province during period (2017-1990 using Landsat satellite images (TM and OLI sensirs) . likelihood maximum method applied to classifying these images. kapa coefficient was used to evaluate the accuracy of the maps and modeling. For predicting land use changes for year 2026, we used CA_Markov automatic cell .studing land use changes trend in Sirjan plain during (1990-1990) showed that the largest area covered by bayer lands with low coverage. this level user has decreased from 88.04% in 1990 to about 84.11% in 2017. During the study period, saline, urban area and agricultural lands has been increasing. saline land increased (with 6.05%) in 1990 to about (6.91 %) in 2017. The urban area were increasing trend observed with 0.23% of the total area in 1990 to 0.85% in 2017. The trend of changes in this use in the first period (2006-1990) has increased from 291.51 hectares to about 952.99 hectares in the second period (2017-2006). The results of evaluating the accuracy of the maps produced for 1990, 2006 and 2017 were 86.7, 89.7 and 88.7, respectively, and the Kappa coefficient for these years was 0.82, 0.84 and 86, respectively. Simulation of land use changes for 2026 showed decresing trend observed in bayer lands with 2.15% about 3792.48 hectares and saline, urban area and agricultural Results increasing trend observed with 2.62%, 64.54% and 28.55 %t, and 155.74, 291.51 and 3185.32 hectares, respective.land use changing has important role in stability ecosystem and its services, and its negative effects are the reduction of the ecological and biological power of the earth, which is also known as the cause of desertification. Land use estimates showed that more than 90% this the area. Based on the prediction for 2026 showed decreasing trend in bayer lands and increasing trend in saline, urban area and agricultural lands. Therefore, if the current strategy of land use in this region continues without consideration for sustainable development until 2026, The rapid changes in land use in different parts of the world have attracted a lot of attention because it has a considerable impact on the physical and economic conditions ecosystems and communities in them. Land use change is a very important indicator for understanding the interaction between human activities and the environment.

The faults and tectonic structures have a major impact on groundwater resources and they play more important role in these factors, which by creating a displacement in the sequence of layers, lead to creation of aquifers. Determination of the relationship between faults and groundwater resources can help to identify new water resources.The aim of this study is to investigate the Spatial Association between Faults and groundwater resources such as Qanats and wells quantitatively and numerically. In order to achieve this goal, the statistical weight of evidence method was used. Thus, by providing the quaternary fault layer and the position of Qanats and wells of the study area in the GIS environment, The 1 km buffers around the faults were extracted. In the next step, by performing the operation of overlaying of the Qanats and wells with the Faults layer, the coefficients of weights of evidence method were calculated. With respect to the changes in the weights and the obtained results, the greatest correlation between the wells and faults is within 1 km of the fault along and the most Spatial Association between the Qanats and faults is within 2 km of the faults along. According to the results, 65% of deep and semi-deep drilled wells in the Sirjan plain are affected by faults, while only 24% of the Qanats in this region are related to the faults. Therefore, by identifying the fault-related wells and Qanats, it is possible to manage the effects of faults activity and possible earthquakes on the discharge change of the wells and Qanats.

The ever-increasing pistachio gardening is considered as the main cause of overdraft and water-level decline in Sirjan plain. During the past several years, overdraft from the alluvial aquifer of this plain has led to water resource depletion, quality degradation, deepening the well, drying water resources, increase in energy consumption for water pumping, higher drought frequency, ground settlement, decrease in specific retention and drying some fields and gardens. Continuation of this trend during the next years, the level of the plain underground water will drop more, and besides discharging a great part of water with a desirable quality and quantity, the damages will also increase. Also, salt water intrusion from the west (Salt Flat) would threaten the natural ecosystems. Problems in public hygiene and welfare, crisis in agriculture and animal husbandry, unemployment, decrease in public income and the probable unrest and economic and social crises may result. Since the highest amounts of abstraction is for agriculture, training farmers for optimum water consumption and up-grading irrigation practices seem essential. Some other options such as decrease in drilling permits, conservation of ground waters, artificial recharge, proper agricultural practices, water treatment and recycling of sewages and effluents may decrease ground water abstraction rate and abate these forecasted consequences.
