Qualitative zoning of groundwater to assessment suitable drinking water using fuzzy logic spatial modelling via GIS

Abstract: Due to shortage of surface water, resources of ground water in Iran (like many other countries with dry and semi‐dry weather) have turned into the most important and reliable source for water supply. Thus, it is necessary to consider the quality of this resource for drinking purposes. The aim of this study was to assessment suitable drinking water based on a fuzzy approach in Asalem region, Iran. For reduce the uncertainty, fuzzy logic spatial modelling via GIS was applied. To receive these aims, four stages w… Show more

“…where Ɣ is the power of the gamma operator entered by the user. Regarding various studies carried out by different researchers such as Lewis et al (2014) and Mohebbi Tafreshi et al (2018) on different fuzzy operators with various applications, they all agreed that fuzzy operator with a power of 0.9 can be introduced as the best operator for overlaying fuzzy layers. The fuzzy logic spatial modelling method to landfill site selection is shown in Figure 3.…”

“…This function creates a linear relationship between the minimum and maximum user-defined values [35,57]. The values below the minimum value tend to be linear and fixed to zero and values greater than the maximum values tend to be oriented toward one [35,34]. In this function, the changes are linear and used when the changes in the classes are fixed [57,34].…”

“…Another study used fuzzy logic to create variogram for spatial analysis of groundwater level interpolation [23], which found to improve the results. Other studies combined fuzzy logic with other tools for groundwater assessment [24], groundwater pollution level [25], and groundwater quality [26]. FL is advantageous as it considers the degree of the truth (not the probability).…”
