Abstract

The study of erosion shows different values depend on the measuring method. In the studied areas, erosion rates have been measured using three different methods: erosion pins (81.0 t/ha.year in BD1 site and 79.1 t/ha.year in BD2); profilometer (118.5 t/ha.year in BD1 and 79.1 t/ha.year in BD2) and dynamic method (100 t/ha.year and 60.5 t/ha.year). Differences between these values shows the importance of select an appropriate technique, furthermore we must taking into account the intrinsical mistakes for each method and different lithologies in which our sites are placed.


Key words: erosion pins, profilometer techniques, dynamic methods, Bardenas Reales.
