Documenting the effects of agricultural land retirement on stream-sediment sources is critical to identifying management practices that improve water quality and aquatic habitat. Particularly difficult to quantify are the effects from conservation easements that commonly are discontinuous along channelized streams and ditches throughout the agricultural midwestern United States. Our hypotheses ...

Thousands of stream miles in the southern Piedmont region are impaired because of high levels of suspended sediment. It is unclear if the source is upland erosion from agricultural sources or bank erosion of historic sediment deposited in the flood plains between 1830 and 1930 when cotton farming was extensive. The objective of this study was to determine the source of high stream suspended sed...

Differential pressure transducers can be used to monitor the suspended-sediment concentration in a water column. Suspended sediments with densities greater than water increase the fluid density, which is determined by measuring the fluid pressure change between two depths. Lewis and Rasmussen (1999) used a densimetric technique under controlled conditions to determine suspended-sediment concent...

Prediction of highly non linear behavior of suspended sediment flow in rivers has prime importance in the field of water resources engineering. In this study the predictive performance of two Artificial Neural Networks (ANNs) namely, the Radial Basis Function (RBF) Network and the Multi Layer Feed Forward (MLFF) Network have been compared. Time series data of daily suspended sediment discharge ...

estimation of river sediment load is one of the most important issues in design of hydraulic structures, investigating water quality, conserving fish habitat, estimating erosion and determining watershed management effects. there are two methods for estimating sediment load: empirical and hydrological methods. existence of numerous empirical methods for estimation of river sediment load and a w...

The paper presents an overview of recent publications on the fluvial suspended sediment flux to the Arctic Ocean. The total suspended matter exported from the Russian territory is 102×10 t/year and from the Canadian Arctic is 125×10 t/year. The total suspended matter (TSM) flux to the Arctic (227×10 t/year) is very low, only about 1% of the global flux. Mean concentrations of suspended matter a...

PAN, C. and HUANG, W., 2010. Numerical modeling of suspended sediment transport in Qiantang River: an estuary affected by tidal bore. Journal of Coastal Research, 26(6), 1123–1132. West Palm Beach (Florida), ISSN 0749-0208. Study of suspended sediment transport in an estuary affected by tidal bore is important for coastal engineering and management because the tidal bore can cause strong sedime...

in this paper, two formulas were chosen among those that estimate the suspendedsediment discharge in rivers. these two formulas were lane and kalinske and bagnold. forstudying and knowing the correlation between input parameters and calculated suspendedsediment discharge (cssd), the spss17 software was used. input parameters in these twoformulas were as: water velocity, water discharge, suspend...
