Better understanding of suspended sediment transport processes allows for better management of both rivers and coasts. Based on field data and sediment transport energy theory, this study presents an analysis on the suspended sediment hysteresis in the Lower Tenryu River of Japan in connection to the channel carrying capacity of suspended sediment and morphological characteristics. The transpor...

The Mara River Basin in East Africa is a trans-boundary basin of international significance experiencing excessive levels of sediment loads. Sediment levels in this river are extremely high (turbidities as high as 6,000 NTU) and appear to be increasing over time. Large wildlife populations, unregulated livestock grazing, and agricultural land conversion are all potential factors increasing sedi...

Geochemical analysis of suspended sediment is a key requirement in nutrient and contaminant transfer studies, but the collection of fluvial suspended sediment samples is problematic due to the highly episodic nature of its transport. Traditional approaches involve the collection of instantaneous samples, but uncertainties regarding intraand inter-storm variations in sedi­ ment-associated nutrie...

So far, many attempts have been made to identify the relation between discharge and suspended sediment load.Empirical relations such as sediment rating curves are often applied to determine the average relationship between discharge and suspended sediment load. This type of models generally underestimates or overestimateswhen sediment load are estimated from water discharge using least squares ...

the offered approach is based on the establishment of the functional dependence between river water discharge (q) and suspended ms ,in a number of observations, which noticeably differs from the mean value (r) of subsequent allocated period(s). the earliest period anthropogenic component during the subsequent period(s) is the difference between an actual suspended sediment yield and its hypothe...

Computation of accurate sediment loads in rivers where the transport of suspended sediment is at least partially regulated by changes in the upstream sediment supply requires high-resolution measurements of suspended-sediment concentration that are collected independently of waterdischarge data. To meet this objective, a multi-frequency acoustic system has been developed and tested on the Color...

A light attenuation sensor system (LASS) for measurements in waters is described in this paper. The LASS records irradiance at multiple levels in the water column to provide a measure of the diffuse light attenuation coefficient which is strongly affected by suspended sediment. Dimensional analysis and geometric optical theory are used to relate the irradiance attenuation to sediment properties...

Transport of suspended sediment between the two reservoirs of a pumped-storage plant in Switzerland was monitored over an 8-month period. A turbidity probe was installed on the upstream end of the pressure shaft, in which real-time monitoring was ensured by automatic data acquisition and remote control. The suspended sediment concentration in the reservoirs varies considerably over the course o...
