PEREZ VEGA, Azucena  and  ORTIZ PEREZ, Mario Arturo. Vegetation change and flood vulnerability in the Papaloapan river lowlands, Veracruz. Invest. Geog [online]. 2002, n.48, pp.90-105. ISSN 2448-7279.

The study showed that the increase in maximum flows in the watersheds of the left side of the River Papaloapan is due to forest cover clearing on shallow slope areas (less than 6°) in the watersheds of the rivers Obispo, Tesechoacan and San Juan Evangelista. Forest clearing affected from 21 to 43 % of the total area of each watershed during the period 1973-1993. The analysis of annual rainfalls in these watersheds indicated no change in rainfall tendency during 1955-1990.
