Valoración de los diferentes métodos empleados en Galicia para la medida de la erosión de los suelos, con especial referencia a los suelos afectados por incendios forestales

Abstract

Several methods for assesing soil erosion that are being applied in Galicia are critically reviewed: theoretical methods of calculation of the Climatic Erosivity, experimental methods of estima te the suspended material carried by streams, measurement of soil loss in experimental micro-basins or according to the cover of buried stakes and microtopographic measurements of soil level. Erosion in Galicia for the Historical Period is also analyzed, according to pollinic diagrams of sediments and to historical documentation.
