Impact on Dongting Lake channel caused by the change of flow and sediment environment after Three Gorges Project impoundment

open access: yesShui kexue jinzhan, 2015
The change of river-lake relation is one of the most important factors affecting the flow and sediment environment in the Dongting Lake area. This has a great influence on the safety and development of lake shipping.

Lateral sediment sources and knickzones as controls on spatio-temporal variations of sediment transport in an Alpine river [PDF]

open access: yes, 2013
Modern mixed alluvial-bedrock channels in mountainous areas provide natural laboratories for understanding the time scales at which coarse-grained material has been entrained and transported from their sources to the adjacent sedimentary sink, where ...

River flow analyses for flood projection in the Kabul River Basin

open access: yesCentral Asian Journal of Water Research, 2020
Flooding is one of the critical natural disasters in Afghanistan, causing huge social and economic losses on an annual basis. Due to lack of historical data and long gaps in the recorded data, flood predictions are usually associated with large ...

Critical stress profile for incipient sediment motion on muddy shoals

open access: yesShui kexue jinzhan, 2012
The vertical profile of critical shear stress is determined using both experimental data and in-situ measurements.A tuning fork densimeter is employed to measure the vertical density distributions of mud on the Lianyungang muddy shoals in Jiangsu ...

Particle reworking and solute transport by the sediment-living polychaetes Marenzelleria neglecta and Hediste diversicolor [PDF]

open access: yes, 2011
This experimental study quantified and compared particle-mixing and solute transport by the polychaetes Marenzelleria neglecta (2 g ww, 3200 ind.m−2) and Hediste diversicolor (2 g ww, 800 ind.m−2) in Baltic Sea sediments.

Sampling Strategies to Improve Passive Optical Remote Sensing of River Bathymetry

open access: yesRemote Sensing, 2018
Passive optical remote sensing of river bathymetry involves establishing a relation between depth and reflectance that can be applied throughout an image to produce a depth map. Building upon the Optimal Band Ratio Analysis (OBRA) framework, we introduce

The use of artificial neural networks to analyze and predict alongshore sediment transport [PDF]

open access: yes, 2010
An artificial neural network (ANN) was developed to predict the depth-integrated alongshore suspended sediment transport rate using 4 input variables (water depth, wave height and period, and alongshore velocity).

Low water temperature sediment transport effects of the hyperconcentrated river: a case study of Bayangaole station in the upper Yellow River

open access: yesShui kexue jinzhan, 2020
The Yellow River is the river with the highest sediment concentration in the world. The sediment transport of the desert-wide valley reaches in the upper Yellow River are affected by inflow, sediment and changes in topographic conditions. To research the

Paleogeographic numerical modeling of marginal seas for the Holocene – an exemplary study of the Baltic Sea [PDF]

open access: yesEarth System Dynamics
The sustainable management of marginal seas is based on a thorough understanding of their evolutionary trends in the past. The paleogeographic evolution of marginal seas is controlled not only by global and regional driving forces (eustatic sea-level ...

Grain-size characteristics and net transport patterns of surficial sediments in the Zhejiang nearshore area, East China Sea

open access: yesOceanologia, 2020
Summary: Spatial variations in grain-size parameters can reflect sediment transport patterns and depositional dynamic environments. Therefore, 616 surficial sediment samples taken from the Zhejiang nearshore area in the East China Sea were analyzed to ...
