BOCCO, Gerardo. El inventario de erosión antrópica: acarcavamientos en la cuenca del río Tlalpujahua, México. Invest. Geog [online]. 1989, n.19, pp.55-68. ISSN 2448-7279.

An inventory of the anthropic erosion in the Tlalpujahua river basin, based upon an applied geomorphological approach, is presented 16% of the metamorphic terrain and 4.5% of the volcanic terrain are severely eroded. As a whole, 5% of the catchment is badly affected. Most of the erosion processes occurs in areas of accumulation, in ondulating terrains, gently sloping to sloping, with moderately deep to deep clayey soils. The main differentiating factor among the erosion patterns in the volcanic and non volcanic terrains is the slope hydrology (superficial flows in the metamorphics vs subsuperficial flows in the volcanics).
