erosion and sediment movement phenomena are one of the most complex issues in management of rivers drainage areas that in water projects are very important. that its measurement wants high time and cost. issue of surface runoff in river basin is a complex issue that human knowledge and understanding about its physical laws a viewpoint of some mathematical formulas is limited. in this study to i...
It is being argued that there will exist high reliance upon agriculture lands and resources as a provider of food for population in coming decades. The increase in urban land, industrial and residential land uses at the expenses of agricultural lands is among the major consequences of population increase. However, the utilization of soil, water, forest and pasture are geared toward extensive an...
The goal of multi-objective land use assessment and allocation (MOLAA) is provision of an optimal allocation of all land uses with maximum suitability. Different techniques of multiple criteria decision making have proven useful as decision support tool for solving a MOLAA problem. SA and MOLA are two different MCDM approaches that can provide solution to a MOLAA problem using different decisio...
land-use planning is a science that determines the type optimum of land-use through studying the ecological characteristics of the land as well as its socio-economic structure. the primary objective of this study is to evaluate the land-use and natural resources for future sustainable land planning using gis. in this study, the makhdoom’s systematic method was used to analyze the ecological and...
Introduction: Awareness of soil quality in agricultural lands and natural resources is essential to achieve maximum production and environmental sustainability. Although soil quality is not directly assessed, soil quality indicators are widely used today, including the physical indicators which are of great importance in measuring the soil quality, as they directly influence the plant growth an...
Improper use of rangelands may lead to their destruction. Therefore, the conversion of these degraded rangelands to agricultural lands and other land uses may improve their soil quality. The purpose of the present study was to evaluate the impact of cultivation in the degraded rangelands on some soil characteristics in Safashahr region of Fars province. Four land uses including the rangeland wi...
land use optimization is one of the appropriate methods for soil conservation which helps decision makers and watershed planners in order to make the optimum decision among different land uses. the main objective of this research was to find the optimum area of each land use to reduce soil erosion rate as well as to increase the income of stakeholders in golroudbar watershed located in semnan p...
Land surface temperature (LST) and land albedo (LSA) are the two key regional global climate-controlling parameters; assessing their behavior would likely result in a better understanding of appropriate adaptation strategies to mitigate consequences climate change. This study was conducted explore spatiotemporal variability LST LSA across different use/cover (LULC) classes northwest Iran. To do...
