Objective: This research study analyzed hydrological surface behavior of the lower basin of the Cauca, San Jorge and Loba tributaries of the Magdalena River in the so-called La Mojana Region in northern Colombia. Methods/Analysis: To determine hydrological behavior of the basins under study, an analysis of vegetation cover was used as the most dynamic condition; its soil use and granulometry as the natural condition, regarding the hydrological pressure degree of the territory, as well as climatic behavior in the last 40 years in the area. Findings: Results show that cover and land use do not contribute favorably to basin hydrological regulation, considering that 45.9% have pasture cover, being this least favored hydrological regulation. Application/Improvements: 92.3% of the total study area (21,650.2 km2 ) shows curve numbers greater than 80, so that there is a high hydrological pressure on the territory. At the meantime, temperature shows a 0.8°C increase, while Evapotranspiration (ET) and vapor density have increases of 50.6 mm and 0.7 g m-1 respectively.
