Determination of Flood Distribution Fields Using AHP Process and Fuzzy Logic in County Shariyar, Tehran Province

Abstract

: Storage and operation of runoff by flood distribution operations in case of heavy rainfall on a large scale can help increase groundwater storage and water supply for agriculture and drinking water. also, by controlling floods as a management solution for floods and water resources, especially in arid and semi-arid regions of Iran, many negative environmental consequences can be reduced. The most important and first step in implementing a flood distribution plan is to locate areas prone to flood distribution and water infiltration into underground aquifers. The present article is taken from a research project that has been done by using one of the multi-criteria decision making methods using geographic information system technology and fuzzy model to determine suitable flood distribution areas in Shariyar county of Tehran province . The study selected six indicators: slope, geology (quaternary), land use, alluvium thickness and electrical conductivity. Finally, using the geographic information system tools and using the Analytical Hierarchy Process (AHP) and with the relevant weight and calculations in the fuzzy model of flood-prone areas in Shariyar county of Tehran was determined.
