Abstract

As a natural well known, but badly measured phenomenon fine sediments can be observed
in suspension in rivers and lakes. In natural rivers the sediment concentration in the suspension is
mostly a function of velocity and turbulence.
However, measurements of sediment concentrations are necessary, important but difficult. These
days especially turbidity probes are used for getting information about sediment concentration
continuously over longer periods. A well-known problem of this kind of measurement is its dependency on grain size, form and colour. A new methodology has been tested at Graz University of Technology for determining the sediment concentration in an easy way. A density probe, manufactured by the company Anton Paar GmbH, has been compared with a turbidity probe and conventional gravimetric analyses. The correlations are promising and the probe seems to be suitable to be used in rivers for measurements of suspended sediment concentration
