Fitting and interpretation of sediment rating curves

Journal of Hydrology, 2000
Abstract A large part of the sediment in lowland rivers is transported as wash load. As wash load is a non-capacity load it often is modelled using empirical relations, such as the rating curve technique. Sediment rating curves in the form of a power function are derived for several locations along the river Rhine and its main tributaries, using ...

Estimation of rating‐curve parameters for sedimentation using a physical model

Hydrological Processes, 2005
AbstractParameters in the lumped sedimentation formula rating curve Qs = KQP are discussed to estimate sedimentation in a basin without calibration in that basin. We were unable to determine the physical meaning of the parameters that are widely used by many researchers.

Single-station estimates of suspended sediment loads using sediment rating curves

Canadian Journal of Civil Engineering, 1993
Sediment rating curves in conjunction with daily flow data have often been used to estimate the total mass of sediment flowing past a given river cross section over relatively long periods of time. Techniques are presented that seek to make the best use of limited noncontinuous suspended sediment concentration data to generate nine partial years of ...

Florida Submergence Curve Revised: Its Relation to Coastal Sedimentation Rates

Science, 1969
New data substantiate as well as modify the south Florida submergence curve, which indicates that eustatic sea level has risen continuously, although at a generally decreasing rate, during the last 6500 to 7000 sidereal years (5500 standard radiocarbon years) to reach its present position.

Reliability of sediment rating curves for a deciduous forest watershed in Iran

Hydrological Sciences Journal, 2010
Abstract The suspended sediment load in a river is an indicator of its health. Yet, the direct measurement of suspended sediment load is difficult. Most assessments of suspended sediment load are therefore estimated from relationships developed between suspended sediment concentration and discharge, as sediment rating curves.

Estimation of suspended-sediment rating curves and mean suspended-sediment loads

Journal of Hydrology, 1991
Suspended-sediment loads are often estimated from an empirical relation between suspended-sediment load (L) and streamflow (S). This relation is usually defined as a power function, L = aSb, and is referred to as a suspended-sediment rating curve. This function can be formulated as either a linear or non-linear model to find the solution of the rating ...

Development of Integrated Sediment Rating Curves Using ANNs

Journal of Hydraulic Engineering, 2001
Correct estimation of sediment volume being carried by a river is very important for many water resources projects. Conventional sediment rating curves, however, are not able to provide sufficiently accurate results. Artificial neural networks (ANNs) are a simplied mathematical representation of the functioning of the human brain.

Channel Geometry Controls Downstream Lags in Sediment Rating Curves

Journal of Hydraulic Engineering, 2018
AbstractIn transport-limited alluvial streams, the suspended sediment concentration C exhibits power functional relationships with the flow discharge Q at a given station.

Use of the Lorenz Curve to Quantify Statistical Nonuniformity of Sediment Transport Rate

Journal of Hydraulic Engineering, 2009
The Lorenz curve and the Gini index are statistical tools that have been widely used to quantify nonuniformity in economics, ecology, and medicine, but have apparently not been previously applied in hydraulic engineering. In this work, the Lorenz curve was applied to the analysis of sediment transport data from several experiments with natural and ...
