abstract the proper management of a watershed depends on recognition of effective elements and investigation of their behavior in different conditions. till date, many researches have studied the role of topographical general characteristics on hydrologic behaviors. whereas, the changeability of hydrologic properties under different conditions, especially in iranian watershed has been rarely ta...

the runoff generation and soil erosion in the kechik watershed, golestan province, was assessed, using a designed and constructed portable rainfall simulator. treatments were applied on different land-uses, slopes and aspects as the most influential factors. results showed that land-use significantly affected runoff generation (13.35 l, 6.9 l, and 4.12 l, respectively for agriculture, forest an...

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...

The paucity of studies on permafrost runoff generation processes, especially in mountain permafrost, constrains the understanding of permafrost hydrology and prediction of hydrological responses to permafrost degradation. This study investigated runoff generation processes, in addition to the contribution of summer thaw depth, soil temperature, soil moisture, and precipitation to streamflow in ...

this study examines the relationship between land use/land cover (lulc) changes and surface runoff generation empirically to reveal how urbanization has altered the hydrologic characteristics of a watershed. a hydrological model, the soil and water assessment tool (swat), is employed to estimate the watershed runoff generation for two lulc scenarios from 2002 to 2010. the cypress creek watershe...

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...

erosion plots were selected for characterizing the effects of main natural factors on runoff and soil loss in a semi-arid region. these erosion plots with an area of 40 m2 are located in the kakhk experimental watershed in gonabad county of khorasan-e razave province in the north-eastern iran. data acquired from 2008 to 2015 include slope, aspect, soil texture and land covers (canopy and litter...

In this study, an integrated system for the comprehensive analysis of climate change, runoff, reservoir operation, and power generation was developed. In order to apply reliable climate change scenarios to the Geum River Basin, we applied representative concentration pathway (RCP) scenarios adopted by the Intergovernmental Panel on Climate Change for its fifth assessment report in 2014 to the s...
