This study analyzes the characteristics of land use/land cover change in Jordan’s Irbid governorate, 1984–2018, and predicts future land use/land cover for 2030 and 2050 using a cellular automata-Markov model. The results inform planners and decision makers of past and current spatial dynamics of land use/land cover change and predicted urban expansion, for a better understanding and successful...
Landslide is one of the destructive phenomena of natural resources and threatens the sustainability of forest roads. The purpose of this study is to determine the zoning of land risk for the stability of forest roads using the process of analyzing the hierarchy in the GIS. The final zoning map of landslide hazard based on the combination of different maps and main criteria of topography, vegeta...
. introduction if environmental hazards, including those with atmospheric origin and terrestrial origin cause economic and human life losses for human societies, they would be considered as disasters. terrestrial hazards, which mostly occur as catastrophic, may have economic and human life damages when they occur in a small scale but with high intensity. mass movements are among the most import...
Cities are experiencing rapid population growth and consequently extensive urbanization. Land-use/land-cover change is one of the important elements worldwide, which significantly affect the environment. This study aims to describe the emergence of urban heat and cool islands as a result of changes in land-use/land-cover. Land surface temperature over a 32-year period in Isfahan city, Iran was ...
nowadays, water supply for sustainable development is one of the most important concerns and challenges in most countries of the world. due to determination of groundwater potential zones are one of the important tools in the conservation, management and utilization of water resources. thus, the present study aimed to prioritize the effective factors on groundwater potential and its susceptibil...
why some learners are willing to communicate in english, concurrently others are not, has been an intensive investigation in l2 education. willingness to communicate (wtc) proposed as initiating to communicate while given a choice has recently played a crucial role in l2 learning. it was hypothesized that wtc would be associated with language learning orientations (llos) as well as social suppo...
Planning, construction and assessment of road network are among the investigations for infrastructure development at watershed scales. The main aim of this study is assessing the road network connectivity in the Chehel-Chay Watershed, located in Golestan Province using Alpha (α), Beta (β), Gamma (γ), Eta (η), network density and detour indices in graph theory. The available road network ma...
Urban planning rules and considering land use regarding faults can change the consequences of natural hazard such as earthquake. Vulnerability risk is increasing in Region 1 because of existence of the north fault, steep slopes and continuous construction of high-rise buildings. It is clear that Region 1’s Master Plan shouldn’t be prepared without considering natural hazard such as ...
â â â in the last years, have been accelerated increased the damages of landslides by natural and anthropogenic factors. one of the main solutions to decrease landslide hazards is avoid from prone areas. for this purpose, it is necessary to prepare the landslide susceptibility map. in this research, after field studies in the ilam dam basin, nine factors including slope gradient, aspect, eleva...
the relative impacts of different types of land use on the surface water quality are yet to be ascertained and quantified. in this paper, the influence of different types of land use on surface water quality is investigated. rain events samples from different land use in the central plateau, iran, were analyzed for major ions. statistical analyses were employed to examine the statistical relati...
