Effects of impervious surfaces and urban development on runoff generation and flood hazard in the Hajighoshan watershed
Urbanization is a pervasive global trend. The development of residential areas and road network in Hajighoshan watershed (northern Iran) has been observed in the recent several decades. The objective of this study is the quantitative investigation of the effects of impervious surfaces development and urban development on runoff generation and flood hazard. The study of urban area development wa...

A novel fractionation method, based on both particle size and settling characteristics, was employed to examine metal distributions among five fractions. In-stream and stormwater runoff samples were collected from four land use types: highway, urban, agricultural (storm event and irrigation), and natural. Highway samples contained the highest dissolved concentrations for most metals, and freshw...

متن کاملStorm water runoff concentration matrix for urban areas.
The infrastructure (roads, sidewalk, commercial and residential structures) added during the land development and urbanisation process is designed to collect precipitation and convey it out of the watershed, typically in existing surface water channels, such as streams and rivers. The quality of surface water, seepage water and ground water is influenced by pollutants that collect on impervious...
متن کاملThe Effect of Mashhad City Development on Its Flooding During 1941- 2016
Impervious surfaces in urban zones, during rainfall, increase the runoff speed and reduce the opportunity for evapotranspiration. This will increase maximum discharge and reduce the time of concentration of flood in urban storm. In this research, the effect of the development of Mashhad on the urban flood has been studied. The EPA SWMM model was used for this study. The studies showed that the ...
