CHARACTERISTICS OF SEDIMENT DISCHARGE AND SEDIMENT TRANSPORT ON BARS

PROCEEDINGS OF HYDRAULIC ENGINEERING, 2008
Sediment control along river is very important for river management. These days, countermeasures to deal with rotational degradation, e. g. placing sand at the downstream of the dam, have been taken in some rivers in order to restore the continuity of sand interrupted by dam. To indicate significance of artificial sediment supply in river, we need know

Prediction of sediment transport capacity based on slope gradients and flow discharge.

PLoS ONE, 2021
Sediment transport capacity (Tc) is an essential parameter in the establishment of the slope soil erosion model. Slope type is an important crucial factor affecting sediment transport capacity of overland flow, and vegetation can effectively inhibit soil

Sediment Transport Mechanisms in a Lagoon with High River Discharge and Sediment Loading [PDF]

Water, 2019
The aim of this study was to investigate the sediment dynamics in the largest lagoon in Europe (Curonian Lagoon, Lithuania) through the analysis of in situ data and the application of a sediment transport model. This approach allowed to identify the propagation pathway of the riverine suspended sediments, to map erosion-accumulation zones in the lagoon

Sediment transport capacity response to variations in water discharge in pressurized subglacial channels [PDF]

The Cryosphere
Sediment transport capacity in both subaerial and subglacial channels depends on the shear stress exerted across the channel bottom, which varies with water velocity and channel width.

Study on effective discharge in the Lower Jingjiang River before and after construction of the Three Gorges Dam

Shui kexue jinzhan, 2018
Effective discharge is the flow rate corresponding to the maximum suspended sediment transport within a certain period of time in a natural river, which can reflect the medium to short term bed-forming effect.

Estimating River Sediment Discharge in the Upper Mississippi River Using Landsat Imagery

Remote Sensing, 2020
With the decline of operational river gauges monitoring sediments, a viable means of quantifying sediment transport is needed. In this study, we address this issue by applying relationships between hydraulic geometry of river channels, water discharge ...

Emergent stationarity in Yellow River sediment transport and the underlying shift of dominance: from streamflow to vegetation [PDF]

Hydrology and Earth System Sciences, 2019
Soil erosion and sediment transport play important roles in terrestrial landscape evolution and biogeochemical cycles of nutrients and contaminants. Although discharge is considered to be a controlling factor in sediment transport, its correlation with ...

Long-term variations in water discharge and sediment load of the Pearl River Estuary: Implications for sustainable development of the Greater Bay Area

Frontiers in Marine Science, 2022
The water discharge and sediment load have been increasingly altered by climate change and human activities in recent decades. For the Pearl River, however, long-term variations in the sediment regime, especially in the last decade, remain poorly known ...

Runoff and Sediment Discharge Variations and Corresponding Driving Mechanism in Jinsha River Basin

Shuitu baochi yanjiu, 2023
The relationship between runoff and sediment discharge in Jinsha River basin has undergone remarkable variations over recent years, which played significantly role in regional ecological sustainable development and the control of water and sediment in ...

Empirical and analytical methods to characterize the efficiency of floods to move sediment in a small semi-arid basin [PDF]

Hydrology and Earth System Sciences, 2018
Over a long multi-year period, flood events can be classified according to their effectiveness in moving sediments. Efficiency depends both on the magnitude and frequency with which events occur.
