Abstract:   (25424 Views)

Namakabroud area is located in the city of Chalus in Mazandaran province. Due to the large limestone formations, the presence of faults and tectonic seams, this area has a high potential for karst formation. The aim of this study is zoning feature of karst formation in this region. The main data of the study include topographic maps and aerial photographs with geological and hydrologic data at the Energy Department. In this study, six factors affecting the karst formation include: Geological, distance from seams and gaps, topography, slope, rainfall and temperature is used. Then these factors using fuzzy logic model in GIS environment are analyzed. At the end of the karst formation final map was prepared using 0.7 Gamma operator. The results show the ability of the region in the karst formation, so that the total area of 221.63 square kilometers study area, 56.65 percent (123.33 km) located in zones with high karst formation. While only 17.13 percent (37.98 square kilometers) in area with karst formation is low. In the end, according to the results of fuzzy model use of these models can help significantly identify areas of karst and zoning of these areas.

Keywords: Namakabroud, zoning, karst formation, fuzzy logic models, geographic information systems (GIS)
