Development of rural tourism activities improves the quality of life, with many associated benefits for local people. Accordingly, this study aims to prioritize tourism areas in Isfahan province using the multiple-criteria decision-making (MCDM) model to provide the best ecosystem services to tourists. Nine rural tourism activities (camel-riding, h...

The purpose of the study is to predict drought changes in Dariun, Fars Province, and their impact on water and soil quality. To prepare drought, water, and soil quality zoning maps, Landsat satellite images and the kriging method were used. The fuzzy maps and weights for each parameter were then determined using fuzzy and analytic hierarchy process...

Earthquakes have caused considerable economic damage and loss of lives. The ability to determine earthquake-prone areas has utmost importance to crisis management. Given the gravity of the issue, this research proposes to incorporate geographic information system-based fuzzy-analytic network process (FAHP) and fuzzy-analytic hierarchy process (FANP...

This study aims to determine suitable locations for artificial recharge of groundwater (ARG) using the GIS-based analytic hierarchy process (AHP) and order weight average (OWA). To determine the weights of the different parameters, the AHP method of pair-comparison was used after preparing a fuzzy map for each attribute. After that, using the OWA–A...

The present study seeks to both estimate and analyze the rate of heavy metal changes in soils of road margins affected by the traffic on Fasa‐Darab road, Iran. Muller index, contamination factor (CF), Geo‐accumulation index (Igeo), potential ecological risk index (PERI), and pollution load index (PLI) were calculated to determine the contamination...

The purpose of this study is to use the GIS-based analytic hierarchy process (AHP) and order weight average (OWA) to determine suitable locations for the artificial recharge of groundwater (ARG). Therefore, after preparing the fuzzy maps for each parameter, AHP method is used to pari comparison and determine the weight of each parameter. Then, usin...

The purpose of this study is to generate maps of contamination risk for cadmium (Cd), copper (Cu), lead (Pb), nickel (Ni), and zinc (Zn) in soils of a large alluvial fan located in Neyriz, Iran and to investigate their possible entry into the food chain. To this aim, the concentrations of the heavy metals of the soils are measured. The Geo-accumula...

To reduce the negative effects of tourism on the environment, the importance of ecotourism is increasingly considered because this form of tourism helps to protect the environment and sustainable development of an area. So, it is important to determine suitable places for tourism to better manage the study area. The aim of this study is to identify...

In the old Lut playa underneath the hills of nebkhas, the deepening of the waterways and the extent of the expansion of the cones and the nebkha morphometry are evidences of environmental changes. To study the above-mentioned factors, it is necessary to rebuild the morphodynamic conditions of the region. In this research, the changes in environment...

Identifying environmental potentials has a crucial role in the construction and spatial planning of our country, especially in the countryside. This article attempts to examine the climate characteristics of the tourism villages located at the northern coast of Iran, which is the south of Caspian Sea, in order to expand and develop the tourism indu...

Forty surface and subsurface soil samples were collected from agricultural field of Darab, southern Iran. Some physicochemical properties and also EC were determined. Geostatistical analysis was done by using the Kriging method (including ordinary, simple, universal, indicator, probability and disjunctive models) in ArcGIS 10.2 software. The result...

In the research aim is to evaluate the Jennes algorithm for landform classification in salt dome of Korsia of Darab plain, Iran. The Jennes’s approach uses a multi-scale approach by fitting a quadratic polynomial to a given window size using least squares. In the study used window size of 3*3 and 10*10. Input data for landform classification is dig...

Role of climatic factors is significant among the factors affecting the erosion of watersheds. The importance of this issue increases with regard to the phenomena of climate change. Therefore in this study using different scenarios of climate change, rainy and gully erosion potential of Kor-chamriz watershed in Fars province was studied applying Ar...

The use of remote sensing for rapid and accurate evaluation of phenomena, specially land covers is very important. In this study, for modeling and estimated of salt dome was used visible atmospherically resistant index (VARI), difference vegetation index (DVI), enhanced vegetation index (EVI), green difference vegetation index (GDVI), normalized di...

In present research work the effect of climate change over the humidex in Iran is analyzed. From this research, we can conclude that the PDIAQ index showed a special sensibility to changes in temperature and relative humidity, hence, it can be an interesting tool, may be even better than the humidex to show the expected effect of climate change in...
