Micro-Zoning Flood Hazard in Lamerd City using AHP, GIS and Fuzzy Method

The occurrence of the flood is considered as one of the most important environmental hazards with high impact in urban areas that threatens the environment, human beings, and human assets permanently. In this research, using AHP model, fuzzy logic and its integration with GIS, the flood phenomenon in Lamerd city in the south of Fars province has been analyzed. For micro-zoning flood hazard, eight important criteria such as natural criteria (distance from the waterways, geology, and slope) and human criteria (road network, urban bridges, residential, agricultural and forest uses, land suitability) have been used. The results show that the flood-hazard area stretches in a broad strip along the northwest-southeast and covers most of Lamerd's urban area. This zone starts from the Zanganeh and Niraiee areas in the northwest of the Lamerd suburbs and includes Mohr -Lamerd highways, Ahmedabad and Ziarat areas. This area stretches along Motahari Street, Jomhuori Street and Moallem boulevard to the south end of the city of Lamerd. Therefore, an important part of Lamerd city and its suburbs are prone to flood hazard and at least half of the city is in a warning condition and the conditions of flooding is very possible.
