The strategy of high-rise construction and development at height as a product of population growth and the lack of suitable land for construction has been popular in recent decades in cities of the world, Apartment living can be considered one of the most important developments in the process of human settlement in cities, which has become a form of urban housing in the contemporary era. use of this method has spread to residential and economic uses such as industrial, administrative and commercial uses, and has also expanded to the surrounding areas of the city, this solution has consequences. And there have been negative effects and it has created new problems for citizens. In this research, the effect of high-rise development on the urban uses of Kerman has been reviewed and appropriate solutions have been presented to organize and reduce the consequences of this phenomenon. The results of the research show that high-rise construction in Kerman has caused a decrease in the open space of residential units per capita, a decrease in the provision of comfort necessary for living, a decrease in green space per capita, better access to urban facilities and services, and an increase in traffic volume. Therefore, preparation of standards for high-rise construction, recognition of the economic and social characteristics of residents, more supervision of legal authorities in construction control, and increasing the reliability factor, and considering the mutual influence of land use planning and urban transportation in the document process of urban plans, among other suggestions is.

Drought has brought about dramatic decline in surface water flows, decrease in underground reservoirs, water, wind, and soil erosion, change in the quality of water and soil resources, an increasing exploitation of underground waters and land subsidence. Hence, it is of prior importance to evaluate drought and its periods in order to reduce the effects of this phenomenon and manage its risks. In this research, precipitation data of the synoptic meteorology station in Saravan during the years 1365-1395 has been applied and drought has been approved through indices such as standard precipitation index, normal percentage index, decile index, Chinese CZI index, reclaimed MCZI index, and Z index. In the present study, there is a high linear correlation between the three indices namely, SPI, ZSI, and CZI pairwise, while the correlation between MCZI with the other above-mentioned indices in 24-month and 48-month time scales is low. High correlation and the conformance of the curves related to the three indices of SPI, ZSI and CZI denotes on the fact that these three indices demonstrate similar results, while MCZI is not the same. Therefore, MCZI must be considered separately in the studies. By routing drought with several indices, this phenomenon seems probable during the years 1396-1400; accordingly, different solutions to manage this crisis such as adaptable cropping pattern with the climate and water resources of Saravan and cultivation resistant plants against drought and rebuilding the qanats of Saravan, and other solutions have been offered.

Aquifer of Saravan is considered part of the drainage basin of Mashkid river. Aquatic potential in different regions of Saravan Basin is different due to the diversity of formations and geological structures and other climatic and environmental factors. In this article, the relationship between qualitative and quantitative characteristics of water and the geological features of the region with regards to petrology and structures has been considered. Thereby, field study, reconnaissance, and the dispersion of geological formations of the determined region of Saravan was done using geological maps. Afterwards, 29 water resources including wells and qanats were selected for sampling and based on the analysis of the results of water samples, the dispersion maps and EC, TDS density of chlorine, sulphate, calcium, magnesium etc. were illustrated. Interpretation of the illustrated maps showed that the northwest of plain of Saravan from Allahabad toward the center of the plain and the western part of the Saravan-Khash road after ChahKhodabakhsh depicted low quality due to influencing factors on geological formations of low water quality and also in suburban areas of Saravan from Hoshak to Porrehkant apart from the effect of geological factors due to population density and the existence of urban sewage systems and at the end of the plain in Dehak area there is low water quality due to the location of underground water evacuation and the accumulation of the silts resulting from the flow of underground water. The best quality is reported to be of the water resources present in Chah Gomban in the south west and Chah Dashto and the Qanat of Gosh in the north of the plain and the surroundings of the granite formations of Koohsefid area in Gosht. It should be noted that the pollution hazard threatens all the water resources in the plain of Saravan.
