Abstract: Understanding the sediment transport processes in sand-bed rivers is a prerequisite for the morphological studies and modelling, and requires sampling of the sand fraction on and close to the riverbed. A limited number of devices are available for these kinds of measurements. This paper discusses the Bed Load Transport Meter Arnhem (BTMA) and the Delft Bottle (DB12), from their original design to the present one. Changes made by the manufacturer for easing the production of the samplers sometimes resulted in less efficiency and even erroneous measurements. Thanks to the feedback from users, improvements have been implemented to both instruments.
