Coastline change of the Yellow River Delta since 1855

2016
The paper analyzes the form of the Yellow River Delta and its driving factor, based on coastlines in 1855, 1937, 1976 and 2013, and nearshore wave characteristics. The Yellow River Estuary was influenced by human beings in low degree from 1855 to 1976, therefore in the state of natural swing and nearly uniformly transporting huge sediment to nearshore ...

Study on Ecological Environment Assessment of Yellow River Delta

Advanced Materials Research, 2013
Some eco-environmental factors are analyzed by RS, and population and GDP spatial distribution are obtained from statistical data. By combining AHP methods for determining weights, comprehensive index method is used to evaluate the eco-environmental quality of Yellow River Delta (YRD) on three scales: raster, administrative region, and delta.

Ice-water pits upon the Yellow River delta plain

Sedimentary Geology, 2006
Abstract The erosion (circular) pit is a common sedimentary structure but its genesis is complex. Many erosion pits occur on the Yellow River delta plain, with some formed by ice-water erosion. The ice-water pits are generally circular or semi-circular in cross-section, and are typically 2–40 cm across and 2–20 cm in depth.

Sediment Resuspension Process in the Modern Yellow River Delta

2019
In this chapter, the process of sediment erosion and resuspension was studied through in situ observations and wave flume experiments. Sediments are more frequently resuspended by wind waves in the Yellow River Delta, the contribution of waves and currents to sediment resuspension was evaluated while also a conceptual model for sediment resuspension in

Yellow River Sediment as a Soil Amendment for Amelioration of Saline Land in the Yellow River Delta

Land Degradation & Development, 2014
AbstractSoil salinization and sedimentation in the Yellow River Delta pose significant environmental concerns in China. This study demonstrated for the first time that the Yellow River sediment can be used as a soil amendment to remediate the salt‐affected soil. Four treatments including the control (CK), Yellow River sediment application at 70 Mg ha−1

[Evolution process and related driving mechanisms of Yellow River Delta since the diversion of Yellow River].

Ying yong sheng tai xue bao = The journal of applied ecology, 2012
Based on the 23 sheets of remote sensing images from 1976 to 2009, in combining with the water and sediment data from Lijin station and the annual precipitation data of Yellow River Basin from 1976 to 2008, this paper quantitatively analyzed the features of water and sediment discharge from Yellow River, and the evolution process of Yellow River Delta ...

Dynamic change of Yellow River Delta wetland nearly 20 years

The 2nd International Conference on Information Science and Engineering, 2010
The authors interpret four remote sensing images using of EDARS8.5 based on field trips and previous data, then get the wetland resource database of the Yellow River Delta in 1985,1996,2000,2004. Carried out in Arcview3.3 overlay analysis, we calculate the 1985–2004 Yellow River Delta wetland transition probability matrix, then analysis the spatial ...

Sediment transportation and bed morphology reshaping in Yellow River Delta

Science in China Series E: Technological Sciences, 2009
The Yellow River Delta supports the ecological function as a typical estuarine foreshore wetland. The wetland area is changing greatly every year because of sediment deposition and erosion, which influences the wetland function tremendously. Application of environmental fluid dynamics code (EFDC) to the Yellow River Delta is on the basis of the mobile ...

Feammox in the Yellow River Delta wetlands is weak

Soil Research
Context Anaerobic ammonium oxidation coupled with iron (III) reduction (feammox) is an important nitrogen loss pathway in natural ecosystems. This is the first research to investigate the feammox process in the Yellow River Delta wetlands. Aims
