Trends and median slope of daily rainfall that can affect aggressiveness cause erosion in the Bogotá - Duitama corridor were studied. For this, records 26 stations (35 years, from 1980 to 2014) evaluated, using Sen's statistic Mann-Kendall test with confidence levels higher than 90%. The studied area covered about 8,100 km2, located between 2,100 3,300 m a.s.l. Colombian Andes. Four positive trends annual found (from 6.90 mm/year 28.80 mm/year) one station a decrease -6.86 mm/year. In order analyze pluvial as main agent soil erosion, Modified Fournier Indices (MFI) generated for periods 10 days. With maximum decadal (MFIdmax) each year, it was possible establish trend (Sen) five three negative trends. Through correlation degree square average values year (MFIdmax2) precipitation, coefficient determination (R2) greater 0.50 found. validation MFIdmax2 explain is new useful methodology land use planning monitoring. this way, developing countries have possibility tool face processes vulnerability adaptation climate change.
