Pollution status of the Yellow River tributaries in middle and lower reaches

Science of The Total Environment, 2020
To determine the water quality status of the primary tributaries in middle and lower reaches of the Yellow River Basin, water collected from the confluence of the ten tributaries and some physical, chemical and biological parameters were analyzed, and then water quality index and health risk were evaluated. Of the ten main tributaries in the middle and

Relative contribution of multi-source water recharge to riparian wetlands along the lower Yellow River.

Journal of Environmental Management, 2022
Rivers play a vital role in both the formation and maintenance of riparian wetland hydrology. However, few studies have focused on the response of water recharge of riparian wetlands to altered hydrological processes induced by water-sediment regulation ...

Coarse sediment and lower Yellow River siltation

Journal of Hydro-environment Research, 2012
Abstract Trap sediment by reservoirs has been effective in protecting the Lower Yellow River (LYR) but it can hard be sustainable. After reviewing the nature of sediment and siltation, the effect of coarse sediment ( d  > 0.08–0.1 mm) (CS) on LYR siltation is studied.

Distribution of PAEs in the middle and lower reaches of the Yellow River, China

Environmental Monitoring and Assessment, 2006
Samples of water, sediment and suspended particulates were collected from 13 sites in the middle and lower reaches of the Yellow River in China. Phthalic acid esters (PAEs) concentrations in different phases of each sample were determined by Gas Chromatogram GC-FID.

Rapid and long-distance channel incision in the Lower Yellow River owing to upstream damming

, 2021
The operation of the Xiaolangdi Reservoir has significantly altered the flow and sediment regime of the Yellow River, which has led to rapid and long-distance channel incision in the Lower Yellow River.

Changes in sediment load in the Lower Yellow River and its driving factors from 1919 to 2021.

Science of the Total Environment
Rivers are not only an essential component of the development of civilization and the carbon cycle worldwide, but also a main contributor to natural disasters, especially the Lower Yellow River (LYR). With the functional degradation of the water-sediment

Effects of large upstream reservoir operations on cross-sectional changes in the channel of the lower Yellow River reach

, 2021
The lower Yellow River (YR) reach is one of the most typical and complex river channels in the world. The impact of human activities on the evolution of its channels is an important scientific issue that needs to be explored.

On the geo-basis of river regulation in the lower reaches of the Yellow River

Science China Earth Sciences, 2011
This paper investigates the important scientific problem of river regulation strategies in the lower reaches of the Yellow River, and discusses the “geo-basis” of river regulation. The concept of a geo-basis to river regulation in the lower Yellow River was discussed in terms of subsidence and sedimentation features of the river plain; channel features,

Multiple isotopes decipher the nitrogen cycle in the cascade reservoirs and downstream in the middle and lower Yellow River: Insight for reservoir drainage period.

Science of the Total Environment
Intensive anthropogenic activities, such as excessive nitrogen input and dam construction, have altered the nitrogen cycle in the global river system.

Estimation of Bankfull Discharge in the Lower Yellow River

Water Resources, 2019
Bankfull discharge is highly correlated with bankfull elevation. The main channels and bankfull elevations in multi-thread sections are ambiguous and need additional indicators to define. Thus, two additional indicators (maximum width and effective width coefficient) were adopted to estimate the bankfull elevation of both multi- and single-thread cross-
