The area was divided in three climatics grounds beginning with the temperate humid climate lands (Th) that reaches to 10.8% of the whole area with temperatures between 19.4 and 24.9?? C. The year average precipitation are about 2173 milimeters with heights varying from 1250 to 1350 meters. Within that climate unit were diferentiated an extensive agradational geoform known by "Dissected Hidrovolcanic Piedemont". The main kinds of soils ocurring in it belong to the Inceptisols Order. This large geoform overcome the limits of the humid temperate climate reaching the domains of the less humid temperate climate lands (Tu). Here, the heights are between 1250 -1000m and ocupy 44% of the whole area, where the landscapes are identifyed as "Body and Base of the ancient Alluvial Fan buried with volcanic ash". In these positions the soils are respectively Ultisols, and Alfisols Molisols Inceptisols and Entisols. Another geoform that appears in this situation is the " Montain and Hilly's relief of Santa Barbara's chain". The end of the area is located in a warm-dry climate lands (Wd) and makes 45.2% of the whole area with heights below 1000m. The temperatures are in the range of 26.4 - 23.3??C and the year average precipitation is 1614 milimeters. The main geoforms are the "Complex Piedemont of Santa Barbara's Mountain" with soils as a Alfisols, and the "Alluvial Valleys" of the Cauca and La Vieja rivers respectively with Molisols and Entisols.  aIndex terms: Alluvial fan  aLandscapes  aTectonic depression  tIn: REGIONAL CONFERENCE ON GEOMORPHOLOGY, ., 1999, Rio de Janeiro.
