The evolution pattern on the YellowRiver delta system
The YellowRiver delta is a fluvial action dominating, highly constructive sedimentary system. The evolution pattern of the delta is closely related to the hydrologic features and the suspended sediment load of the YellowRiver as well as the river
mouth depositional forms and the diversion mode of the river's lower courses.
Land accretion of the YellowRiver delta as influenced by drainage basin factors
In this study, an effort has been made to elucidate the effect of changing human activities and precipitation on land accretion of the YellowRiver delta, to provide a stronger basis for environmental management in the YellowRiver drainage basin
Anthropogenic effect on the flow and sediment of the lower YellowRiver and its bearing on the evolution of YellowRiver delta, China
This paper discusses the remarkable effect of flood discharge, unusual drought and strong storm surge on the evolution of the YellowRiver delta and shows that in the study of deltas, greater attention should be paid to the rare events.
This paper aims at expounding the essence, criteria, indicators and methodologies to build a healthy YellowRiver, which provides theoric guidelines to the implementation of the new river management concept.
Causes for continuous siltation of the lower YellowRiver
This paper intends to separate the effects of the upriver control and the downriver control on the aggradation of the lower YellowRiver and to discuss historical changes of factors influencing the river aggradation.
Researches on environmental changes of the YellowRiver Basin and laws of water and sediment transportation
In this project, some basic researches on the prospect of reducing sediments delivered into the YellowRiver after 2000, the ways to prolonging the lifetime of the current lower YellowRiver channel, the program of comprehensive management
and development of the drainage basin, etc., were carried out. Moreover, this project has outstanding features comparing with other researches on the large rivers in China.
Dynamic analysis of evapotranspiration based on remote sensing in YellowRiver Delta
In this study SEBAL, an evapotranspiration (ET) computation model using remote sensing method is applied in the YellowRiver Delta where water resource faces a rigorous situation. Three Landsat TM images and meteorology data of 1999 were used for ET
computation, and spatial and temporal change patterns of ET in the YellowRiver Delta were analysed.
The fluvial process of the lower YellowRiver and its extension of river mouth deposits.
The old beds of the YellowRiver can be found almost everywhere on the North China Plain. The cyclical process of the estuary development, namely, rerouting, extending, and rerouting again, is an epitome of the estuary development in the past
but on a big scale now. The extension of the river mouth is the direct cause of aggradation of the river bed above the point of estuary pivot, arising from large sediment load consequent to soil erosion in the upland areas. (TNC).
Studies on terraces and river system changes of the upper YellowRiver
There are 7 steps of terrace both in the Guide basin and Gonghe basin along the YellowRiver. 3 ancient terraces are found in the Gonghe basin. The upper reaches of the YellowRiver was joined up by a series of stream captures at different periods
of time, the ancient YellowRiver linked up the Gonghe basin and Guide basin at the end of the middle Pleistocene, the Longyangxia gorge developed around 60 Ka.B.P., and the gorge between Maqu and Tangnag developed around 20 Ka.B.P.
Environmental consequences of human activity on the YellowRiver and its delta, China
The YellowRiver is unique among the major rivers of the world because of its extremely heavy sediment load in relation to its small discharge. The YellowRiver has changed courses numerous times during the past 5000 to 6000 years. The abandoned
of the changes occurring in the YellowRiver and its delta.
deltas are eroding, whereas the present delta being formed in Bohai Bay is growing rapidly. Human activity, including extensive agriculture, heavy water consumption, the use of river-control structures, and war, has been responsible for many
A sediment budget of the lower YellowRiver, China, over the period from 1855 to 1968
and amounts of deposition in the lower YellowRiver and the modern YellowRiver delta were estimated for completing the sediment budget. The details of the sediment budget show that the importance of sedimentation in the lower YellowRiver changed greatly
The framework of the sediment budget includes 4 functional units with the upper and middle reaches of the river as the sediment source and its lower reaches, its delta, and the deep sea as the sediment sinks. Sediment yield from the source
Sediment load and storage in the lower YellowRiver during the late Holocene
This study determined sediment storage on the floodplains of the lower YellowRiver in 5 historical periods after the year 602 BC mainly based on data of boreholes, radiocarbon dates in the Huang-Huai-Hai Plain and maps of historical changes
of the lower YellowRiver channel. Furthermore, the mean annual sediment outputs from the upper and middle reaches of the YellowRiver were calculated in the 5 periods through investigating the sediment delivery ratio of the lower YellowRiver under different
conditions of artificial levees. The Loess Plateau is the principal sediment source of the YellowRiver. The comparison of historical changes in sediment load of the lower YellowRiver with those in the natural conditions and in human activities
Human impact on coastal landform and sedimentation. The YellowRiver example
This paper documents a unique case of the dominating role of man in coastal evolution and hydrological changes in North Jiangsu province. Owing to human breaching of dikes on the Lower YellowRiver in 1128, a large anthropogenic delta, the Abandoned
YellowRiver Delta was formed. Its rapid growth and quick decay over a period of 400 years further illustrates the overwhelming influence of human activity in triggering coastal changes. Man's diversion of the YellowRiver to Jiangsu has also resulted
Historical bank-breachings of the lower YellowRiver as influenced by drainage basin factors
The bank-breaching frequency of the lower YellowRiver has been adopted as a proxy index to study the historical sediment-related disasters, and then it has been related to various indices describing the natural and human factors of the YellowRiver
basin. Consequently, some corelations have been established. Human activities are the major factor influencing sediment-related disasters in the YellowRiver.
Relation between the erosion and sedimentation zones in the YellowRiver, China
The upper and middle drainage basin of the YellowRiver has been divided into 4 major sediment and water source areas. A series of databases of runoff and sediment yields from these source areas and for the corresponding quantities of sedimentation
in the lower YellowRiver channel have been established. On this basis, a set of multiple-regression equations has been established that define the relationships between sedimentation in the lower YellowRiver and the yearly or event-based runoff and sediment
A study of long term environmental effects of river regulation on the YellowRiver of China in historical perspective
Through an analysis of both the historical and the present-day processes, an effort has been made to deal with the long-term environmental effects induced by man's regulation of the YellowRiver of China, which was started more than 2,000 years ago.
Formation of river terraces and evolution of drainage system in the middle reaches of the YellowRiver
On the basis of field data and by paleosol-dating method, it is concluded that the YellowRiver of this segment and its main tributaries were formed 1670-1450 ka ago, afterwhich six terraces and two valley flats have developed. The evolution
