remote sensing is a key technology for assessing expansion and rate of land cover changes that awareness of these changes as the basic information has a special importance for various programs. in this study, land use changes were examined over the past 24 years, and the feasibility of predicting it in the future was evaluated by using the markov chain model of the abbas plain. landsat tm, etm+...
Land use change is one of the most important factors of global environmental change. So, understanding and predicting the causes, processes and consequences of land use and land cover has become a major challenge. The Remote Sensing and Geographic Information System (GIS) technologies can be used effectively to detect and quantify of land use changes and its effects on the environment. The pur...
Assessment of land use spatiotemporal changes provide valuable data for managers to elaborate plans. Land use change modeling is one of the methods used by planers to manage land use changes. Detection of such changes may help decision makers and planners to understand the factors in land use and land cover changes in order to take effective and useful measures. Remote sensing (RS) and geograph...
Quantifying land use change dynamics is critical in tackling environmental and socio-economic challenges such as climate change in recent years. This study takes Siahkal County in Guilan Province as the research subject and analyzes the land use changes in two different years: 2000 and 2021, and predicts the change in 2031. We carried out land use change analysis using LANDSAT-7 ETM+ and LANDSA...
Abstract Change in land use pattern influenced hydrological processes in basin and disrupt the normal balance of water flow. In the present research, hydrological parameters change of Babul Rod watershed basin has been that investigated concluded of land use changes in 1988 and 2009. To determine land use changes of Babul Rod watershed basin we has recruited TM satellite images 1988(1367) year ...
Substantial population growth and urbanization arbitrarily banning the exploitation of natural resources and environmental factors adversely impacts the environment and resources necessary for nutrition and healthy life styles. The secret to success and survival of ecosystems depends on a stable, continuous monitoring of the environment. The SWOT model has been developedto consider all int...
owing to the vital effects of future land use changes, it is necessary to predict land use growth pattern before any decision making by the authorities and decision makers. purpose of this research is to model land use change of kohmare scorch plain of shiraz province using ordinary least squares regression (ols) for pre-processing variables and modeling using neural networks. to perform this m...
predicting the hydraulic behavior of the river and flood zone determination to reduce probable damages, are among measures which in recent years has been the attention of many researchers. mazandaran province, especially the city of neka, each year is affected by the floods with different return periods; therefore, land use changes and the role of these changes were evaluated in flood zones. in...
INTRODUCTION Since the land use change affects many natural processes including soil erosion and sediment yield, floods and soil degradation and the chemical and physical properties of soil, so, different aspects of land use changes in the past and future should be considered particularly in the planning and decision-making. One of the most important applications of remote sensing is land ...
Not only have recent global challenges including drought, climate change, land degradation and land use change impacted the quantity of available surface water and groundwater, but also water quality has been affected as well. To study this impact, Landsat 5 satellite images and water quality data were obtained to compare the effects of land use changes on surface water quality between July of ...
