Analyses of suspended sediment loads in Slovenian rivers [PDF]

open access: yesHydrological Sciences Journal, 2016
ABSTRACTSuspended solids are present in every river, but high quantities can worsen the ecological conditions of streams; therefore, effective monitoring and analysis of this hydrological variable are necessary. Frequency, seasonality, inter-correlation, extreme events, trends and lag analyses were carried out for peaks of suspended sediment ...

An Evaluation of various developing methods for sediment rating curve and computer simulationmodels for sediment load estimation in Mazandaran basin, Iran [PDF]

open access: yesعلوم و مهندسی آبیاری, 2017
A sediment curving rate is a method to describe the relationship between river discharge and suspended sediment load for a particular location. The rating curves have been used to predict sediment load by hydrologists for more than sixty years (Horowitz,

Impact of Reduced Fluvial Sediment Supply on Saltwater Intrusion in the Yangtze Estuary

open access: yesEarth's Future, 2023
A decline of the fluvial sediment supply leads to coastal erosion and land loss. However, the fluvial sediment load may influence not only coastal morphodynamics but also estuarine hydrodynamics and associated saltwater intrusion.

Sediment sink-source transitions in the middle and lower reaches of the Yangtze River estuary

open access: yesFrontiers in Marine Science, 2023
Human activities have severely altered the Yangtze River (Changjiang) Estuary’s pattern, beach-trough shape, and delta in recent decades. Existing research has studied the sediment “source–sink” relationship between the Yangtze River mainstream and ...

On the Issue of Calculation of the Suspended Sediment Load Discharge

open access: yesWater sector of Russia: problems, technologies, management, 2020
The article deals with the questions of the contribution of suspended sediment in the processes of formation of the channel, and includes several formulas of suspended sediment discharge calculation and the results of calculations by these formulas. An analytical formula of sediments, in which the absolute exponent of the degree of arguments is equal ...

Impact of land use-land cover change on spatio-temporal trends in seasonal stream flow and suspended sediment load of Godavari basin from 1969 to 2019

open access: yesJournal of Water and Climate Change, 2022
Assessment of long-term trends in stream flow and sediment load is important for adopting soil and water conservation measures and for predicting morphological changes in rivers. In the present study, detailed quantification of the nature of the trend in

Influence of Suspended Sediment Load on Roughness Coefficient and Intensity of Flow Turbulence (Case study: Haraz, Rostamabad and Beheshtabad Rivers) [PDF]

open access: yesمحیط زیست و مهندسی آب, 2020
Estimating the effect of sediment transport, especially suspended load, is important in river planning and management. The aim of this study was to investigate the effect of suspended sediment load on the roughness coefficient and the intensity of flow ...

River Flow with Excessive Suspended Sediment Load [PDF]

open access: yesHydrology Research, 1986
River flows with high volume concentrations (20-50%) of silty sediments generally imply that the mixture has non-Newtonian properties. In this study, the rheological behaviour of mixtures with solids particles smaller than 0.1 mm was identified experimentally with viscosimeters.
