Abstract
An experiment on water discharge gauging and suspended sediment sampling performed in the Amazon River basin on 24 March 1995, during a rising-water period is described. The experiment involved different devices, including an Acoustic Doppler Current Profiler (ADCP) for water discharge measurements. From the different samplers used, one specially built for the HiBAm project was tested successfully. An attempted use of the relationship between the ADCP signal and the total suspended sediment (TSS) was performed for sediment yield calculations. Different calculation methods were used with the TSS data obtained by the samplers and the results are discussed. The mean water discharge (Q) and TSS sediment yield (Qs) results were 172 400 m3 s-1 and 3.15 × 106 t day-1, respectively. A relationship between the Qs value at depth and the surface Qs value is also proposed.

This paper reports an experiment performed at Óbidos on 24 March 1995, by the HiBAm team, using for the first time an Acoustic Doppler Current Profiler (ADCP) operated together with different water samplers, including one built for the HiBAm field cruisers. [Note: HiBAm is a Brazilian abbreviation for the Hydrology and Geochemistry of the Amazon River Basin Project conducted by CNPq – the Brazilian Research and Technology Council and IRD – the French Research Institute for Development.] This test evaluated the performance of Doppler technology for water discharge measurements, sediment sampling, and TSS discharge calculation using different methods, beneath the largest river of the world.
