Computation of sediment transport and presentation of results
This article is a summary of chapter 4 of the Manual Sediment Transport Measurements in Rivers, Estuaries and Coastal Seas ^{[1]}. This article introduces how the total load transport can be calculated. A more complete article on this topic is Sand transport.
Calculation of load transport
When the suspended sediment samples are collected as pointintegrated samples, there are two methods to compute the depthintegrated suspended load transport. First, there is the socalled partial method which gives the suspended load transport between the bed and the highest sampling point using a linear interpolation between adjacent (measured) values. Second, there is the socalled integral method, which gives the total suspended load transport between the bed and the water surface by fitting a theoretical distribution to the measured flow velocity and concentration profiles. Applying this latter method, the suspended load in the unsampled zone is taken into account. The transport rate of the suspended silt (2 to 63 um) and suspended sand particles (>63 um) should be computed separately. If necessary, more fractions can be used.
The total load transport can be obtained by summation of bed load and suspended load transport.
