[Resumen] [Abstract] An automatic station for monitoring bedload transport has been installed in a gravel-bed river. The station has two slot samplers with the pressure-pillow system (Birbeck-type) that allow a continuous measurement of bedload transport. The paper shows the bedload sampler operation, the load tests and the first results obtained. It is the first time that bedload transport is registered continuously in a river of the Iberian Peninsula.

Snow depth and the movement of selected blocks at each site were recorded from October 1990 to June 1995. The relationship among late-lying snowpatches, geomorphologic heritage and current erosive processes was deternúned.
