The practicalities of suspended sediment load estimation in South Africa

2022
In many parts of South Africa, soil erosion rates are high, and likely to be exacerbated by the longer droughts and more intense rainfall that are predicted in long-term regional climate change scenarios. Suspended sediment loads (SSL) and yields (SSY) are accepted means of expressing and comparing sediment transport and soil erosion rates.

Mercury and Suspended Sediment Loadings in the Lower Minnesota River

Environmental Science & Technology, 1996
Mercury (Hg) enters rivers from both diffuse and point sources; control strategies should be based on reliable estimates of loadings from both source types. In this study, diffuse and point source components of total Hg loadings in the Lower Minnesota River (Minnesota) were character ized using clean sampling and analytical techniques.

Suspended sediment and bed load problems of the Upper Rhine

CATENA, 1990
Summary The regulation of the southern Upper Rhine by dams down to Iffezheim has considerably changed the sediment balance of the stream. In the impounded sections fine-grained sediments are deposited, narrowing the cross section and thus impeding high-water discharge.

The impact of persistent dynamics on suspended sediment load estimation

Geomorphology, 2018
Abstract Fluvial suspended sediment concentration and discharge is most commonly estimated by applying rating curves developed over a given base period of sediment monitoring to longer, continuous records of water discharge. This practice invokes the tacit assumption of stationary suspended sediment concentration–water discharge relationships (i.e ...

Turbidity and the suspended sediment load of the regulated River Tees

2021
The physical effects of river regulation in the U.K. by impoundments have attracted most attention from hydrologists and engineers concerned with predicting and maintaining discharge regimes for water supply. Grimshaw & Lewin (1980) suggested two basic methods to investigate the effects of regulation on suspended sediment discharge: (i) Compare the ...

Bias and variance of some estimators of suspended sediment load

Hydrological Sciences Journal, 1990
Abstract Walling & Webb (1981) made empirical comparisons amongst a number of methods for the estimation of suspended sediment loads. This paper presents expressions for the means and variances of three of the estimates compared by Walling & Webb, on the assumption that suspended sediment concentration, c, and mean daily discharge, q, are bivariate ...
