First, there is the so-called 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 so-called 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.

Calculation of load transport

When the suspended sediment samples are collected as point-integrated samples, there are two methods to compute the depth-integrated suspended load transport. First, there is the so-called 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 so-called 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.
