ABSTRACT This study seeks from remote sensing techniques and GIS delineate the floodplain by the overflow occurred Soapaga river (Paz de Río sector, Boyacá); flooding occurs due to two factors: the strong rainy season occurred during the first half of 2012 and generated instability geological agents on the ground, causing damage to homes, water and sewer networks, roads, bridges, etc., located in urban area. The flooded area is determined from vector data (contours) obtained from the digital elevation model (DEM), assuming that the level of the flood did not exceed two meters in height from the middle of the Soapaga river and taking benchmark the dimension 2210. Additionally, it takes a geoprocessing layer between the municipality’s urban farm and the area enclosed, to estimate the number of farms and areas affected by the flood.

Palabras clave : Floodplain; digital elevation model; geoprocessing.
