BOCCO, Gerardo. Análisis estadístico de datos hidrometeorológicos en estudios de erosión acelerada: Un estudio de caso en la cuenca del río Tlalpujahua, México. Invest. Geog [online]. 1989, n.20, pp.9-27. ISSN 2448-7279.

The statistical analysis of hydrometeorological data is proposed in order to assess the influence of the relationship precipitation/runoff in the development of man-induced gullies. The results allow two logical models of erosion development. In the metamorphics: less antecedent moisture required for runoff to start → quick hydrologic response → superficial flows → gullies. In the volcanics: more antecedent moisture → delayed hydrologic response → soil slumping → gullying in disturbed areas.
