University of Tabriz Journal of Hydrogeomorphology 2383-3254 3 7 2016 08 22 Determine Appropriate Sites of Urban Development Based on Geomorphologic Elements (Case Study Urmia) Determine Appropriate Sites of Urban Development Based on Geomorphologic Elements (Case Study Urmia) 39 57 5280 FA Sayyad Asghari Batool Zeinali Saleh Asghari Journal Article 2015 07 06 Sayyad Asghari[1]* Batool Zeinali[2] Saleh Asghari[3] Abstract The location of human settlements and other facilities created by human are affected by Environmental factors, particularly geomorphology and geology. Today, as a result of population growth, development of construction is inevitable and the adverse impact of human needs on the ground as well as operation of areas around city and villages for creating of home and economic and industrial facilities have increasing expansion. Meanwhile, a plurality of geomorphological factors and dynamics of the natural environment makes difficult possibility of assessment all factors in order to recognize the best location for the placement elements of development. So the use of efficient methods of evaluation will be the most important measures for better planning. Accordingly, the aim of present study is using from Topsis method to locate the best places of natural and geomorphologic structure for future development of Urmia. In this study with entering of area data layers to the ARC GIS and based on topographic factors, the most important constraint of morphological Urmia, was diagnosed three sites suitable for development that proposed sites using natural and morphological components and by techniques Fuzzy ANTROPY (for index weighting) and TOPSIS (to prioritize sites) were evaluated. According to research, site C in the eastern part of the city by a factor of 0.76877 CI as the best place in Urmia is intended for future development.
