Every year, due to population growth and economy development, land uses and land covers are changing. The various types of land uses have significant roles on components of water balance of a watershed. The simulation modeling has the capability to predict floods, to evaluate land use impacts on floods, and to make decision in watershed management. In this research, the effects of land use chan...

increased soil dryness of hillsides and lands around the gully causes the aggravation of the gully erosion which leads to the desertion of the environment. soil moisture contents are various in different soil depths, gully positions, and in various land uses. these are fundamental for ecosystem sustainability in arid and semi-arid area. therefore, understanding the behavior of soil moisture in ...

Allocating urban land-uses to land-units with regard to different criteria and constraints is considered as a spatial multi-objective problem. Generating various urban land-use layouts with respect to defined objectives for urban land-use allocation can support urban planners in confirming appropriate layouts. Hence, in this research, a multi-objective optimization algorithm based on grid is pr...

This paper examines the inter-relationship of three major phenomena- population growth, uncontrolled urban expansion and urban development in Ado Ekiti, Nigeria. Uncontrolled urban expansion has a resultant effect on the urban development of a city whereas uncontrolled urban development is caused by uncontrolled population increase is caused by Migration. This work encapsulates how population g...

introduction: heavy metals are found to be one of the major environmental hazardous contaminants, for human health, animal life, air quality and other components of environment. they can affect geochemical cycles and accumulate in animal tissues since physical processes are not able to remove them, so they are consistent in long term. the analysis of the total concentration of heavy metals in s...

The urban heat island effect is linked to the built environment and threatens human health during extreme heat events. In this study, we analyzed whether characteristic land uses within an urban area are associated with higher or lower surface temperatures, and whether concentrations of ―hot‖ land uses exacerbate this relationship. Zonal statistics on a thermal remote sensing image for the City...

Recent studies have produced conflicting findings about the impacts of local nonresidential land uses on perceived incivilities. This study advances work in this area by developing a land-use perspective theoretically grounded in Brantingham and Brantingham’s geometry of crime model in environmental criminology. That focus directs attention to specific classes of land uses and suggests relevanc...

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...
