sediment concentration

sediment concentration

[′sed·ə·mənt ‚kän·sən′trā·shən]
(hydrology)
The ratio of the dry weight of the sediment in a water-sediment mixture (obtained from a stream or other body of water) to the total weight of the mixture.

It represents an additional and efficient option to overcome the limitations of traditional suspended sediment concentration (SSC) monitoring (Pavanelli & Bigi, 2005).
The international team behind this latest research developed a new method of analysing archived measurements of water discharge into the Mekong River to detect sediment concentration dating back over two decades (1981-2005).
Table-5: Mean values for the total aromatic hydrocarbons (TArH) in the studied sites compared with the sediment quality guidelines [33]: sediment concentration (ppm, dry weight), effects range low (ERL), and effects range median (ERM) for the five sites.
Runoff rates and sediment concentration were used to calculate the sediment yield, total runoff, runoff coefficient, and erosion rates.
The independent variables of discharge and sediment concentration are single- valued functions and, therefore, are applicable to cases where the discharge is relatively uniform with time.
Equally appropriate for agricultural engineering, civil engineering, and hydrologic science, this graduate textbook introduces Shannon entropy, the principle of maximum entropy, concentration theorem, and the principle of minimum cross-entropy, and applies the concepts to sediment concentration and discharge, hydraulic geometry, channel design, water flow rating curves, water level monitoring networks, and reliability analysis of water distribution systems.
The equilibrium time is when the outlet sediment concentration reaches a constant value.
The sediment deposition and retention in the inundated valley increase quickly with rising water discharges, since in this case the sediment discharge also increases, and the decrease of sediment concentration because of their deposition is then compensated in the main channel.
In the watershed with high-intensity recreation, the stream consistently carried 8x the daily average sediment concentration than the stream in the watershed with low-intensity recreation.
This may be associated with high concentrations of Ni and Cu in water samples observed at sites A2 and A6 and high sediment concentration of Zn observed at site A3.
Two rainfall intensities were compared and evaluated for soil loss and sediment concentration at the equivalent of a total rainfall amount of 40 mm, although the kinetic energies of the simulated rainfall for 60 and 40 mm/h, which were computed using the formula proposed by van Dijk et al.
