Abstract

The occurrence of natural disasters due to the climatic characteristics of Iran's domains on the one hand, and rapid population growth and increased need for food, destruction of water and soil resources, environmental degradation and development of desert areas. Providing water and optimal utilization of this vital element is inevitable in order to cope with the process of destruction and the prevention of desertification. In this regard, there is undoubtedly the sustainability of efficient methods in addition to observing the principles of science and applying methods adapted to the conditions of time and place so that among the various options for supplying water, it is possible to use all the natural powers. In arid and semi-arid regions, which have low dispersal atmospheric discharges, disproportionate dispersion is significant, and significant volumes of runoff are released from leaks and flood flows. In such a situation, planning and performing the basic and essential measures required to provide the necessary conditions for the identification of suitable land for the construction of flood exploitation systems from the droughts. Considering the fact that the province of Tehran witnesses the flood event and its damages every year, this article is the result of a research project that, through existing techniques in remote sensing and geographic information systems, to zoning areas susceptible to flood spreading in the study area and considering variables such as geological maps and quaternary formations, hydrology, land use, landslides, land suitability maps, and the use of fuzzy logic in integrating these layers, ultimately, to identify the most appropriate place for the construction of interest systems The flood was taken in county Pakdasht of Tehran province.
