Abstract
An overview of modern bed load measurement methods in rivers with fine alluvium is performed. Four groups of the methods are identified: measuring with bed load samplers, dune-tracking with a single-beam echo-sounder, dune-tracking with a multi-beam echo-sounder and measurement using acoustic Doppler current profilers. Strengths and weaknesses of each method are considered. Due to the fact that bed load transport occurs in the form of dunes the most promising methods seem to be based on the use of echo-sounders since they make it possible to take into account the integrity of bed forms directly.
