Rapid changes to global river suspended sediment flux by humans

open access: yesScience, 2022
Rivers support indispensable ecological functions and human health and infrastructure. Yet limited river sampling hinders our understanding of consequential changes to river systems.

Suspended Sediment Concentration Estimation from Landsat Imagery along the Lower Missouri and Middle Mississippi Rivers Using an Extreme Learning Machine

open access: yesRemote Sensing, 2018
Monitoring and quantifying suspended sediment concentration (SSC) along major fluvial systems such as the Missouri and Mississippi Rivers provide crucial information for biological processes, hydraulic infrastructure, and navigation.

Measuring and modeling suspended sediment concentration profiles in the surf zone

open access: yesJournal of Palaeogeography, 2012
Time-averaged suspended sediment concentration profiles across the surf zone were measured in a large-scale three-dimensional movable bed laboratory facility (LSTF: Large-scale Sediment Transport Facility).

The impact of submarine cable laying on the surrounding marine environment in Lvhua Island

open access: yesEnergy Reports, 2022
In the process of laying the submarine cable on Lvhua Island, the sediment movement affects the surrounding area. A 2D hydrodynamic model about the Lvhua Island and its surrounding is established by MIKE 21.

Sediment Curve Uncertainty Estimation Using GLUE and Bootstrap Methods

open access: yesمجله آب و خاک, 2017
Introduction: In order to implement watershed practices to decrease soil erosion effects it needs to estimate output sediment of watershed. Sediment rating curve is used as the most conventional tool to estimate sediment. Regarding to sampling errors and

Diel patterns of suspended sediment flux and the zoogeomorphic agency of invasive crayfish

open access: yesCuadernos de Investigación Geográfica, 2014
The role of biotic forcing in fluvial geomorphology is understudied. This paper investigates the suggestion that the activities of signal crayfish (Pacifastacus leniusculus) can increase suspended sediment fluxes in rivers. Previous field work, supported

Determination of sediment delivery ratio in draining systems [PDF]

open access: yesActa Scientiarum Polonorum. Formatio Circumiectus, 2019
Determination of the amount of sediment that outflows from the draining system via ditches, based on the known intensity of erosion processes in the catchments of this system, requires the calculation of a sediment delivery ratio (SDR).

Study on the Impact of Typhoon Maria (2018) on Suspended Sediment in Hangzhou Bay, China

open access: yesAtmosphere, 2023
Sediment transport in coastal waters has an important impact on the siltation of port channels and changes in the estuary ecological environment. The southeast coast of China is often hit by typhoons, which can affect the suspended sediment concentration

Estimating Suspended Sediment Concentration by a Neaural Differential Evolution and Comparision it with ANFIS and RBF Models (Case study : Givi Chay River ) [PDF]

open access: yesجغرافیا و توسعه, 2015
In this study, neural differential evolution (NDE) models were used to estimate suspended sediment concentration. NDE models are improved by combining two methods, neural networks and differential evolution.

Study on the Vertical Distribution Characteristics of Suspended Sediment Driven by Waves and Currents

open access: yesJournal of Marine Science and Engineering
Port coasts are affected by waves and tidal currents, and sediment continues to silt up, leading to a reduction in the depth of water in the channel, blocking the channel and seriously affecting the safe operation of ports.
