The delayed response of fluvial rivers to external disturbances has been described by many researchers.To simulate such behavior,the rate law model (or the delayed response model) was developed by previous researchers,and has been applied to a series of r
The dispersion and influence of soluble and particulate trace elements (TEs) present in the materials from abandoned mines is an imminent problem on terrestrial and aquatic environments.The goal of this research is to provide a broader view of such transp
Selective removal of particles and nutrients by water erosion is a key factor in soil erosion studies.Most agricultural soils are located on gentle slopes where fertility is high;however,until now,the main attention on sediment transport mechanisms was pa
The significant reduction of sediment load flux into Lake Baikal from its main tributary-the Selenga River began in the mid-1970s,and can be explained by climate change and socio-economic activities.Integrated analysis was done of changes in hydro-meteoro
This study focuses on the prediction of the porosity of nonuniform sediment mixtures,considering the effects of particle packing.A random particle packing model has been developed for the porosity of bimodal mixtures by extending the existing random parti
Among braided rivers developed on the Qinghai-Tibet Plateau of China at very high elevations(>3,500 m),the middle and lower reaches of the Lhasa River have been affected by comprehensive human activities mainly involving dam construction,urbanization,farm
As economic development upstream in the Yangtze River basin has progressed in recent decades,the demand for sediment has rapidly increased and contributed to an expansion in sediment excavation that may affect the river\'s stability and navigation safet
Wind-blown sand is one of the key factors affecting the evolution of sediment transport,erosion,and deposition in rivers crossing desert areas.However,the differences and complex variations in the spatial and temporal distribution of the underlying surfac
Water depth,salinity,current,and suspended sediment concentration (SSC) were measured along with the grain size distribution of bed sediment along an estuarine longitudinal section.The floc size increased with increase in the percentage of clay and silt,w
以门座起重机为研究对象,对其金属结构进行应力谱测试,通过雨流计数法进行数据分析处理,利用Miner线性累积损伤理论计算出金属结构的疲劳寿命.结合门座起重机的实际使用工况,计算出实际安全使用期限及剩余安全使用期限.
