| Sumario: | In the present work a description of the geomorphology, with special attention on the hydrologic system of Bella Vista town at Corrientes Province, located between Paraná River and the provincial route Nº 27, which determines the expansion of the urban plot, making it to grow progressively to the south. Its urban area is located at an altitude of 67 meters above sea level (IGN) presenting an unevenness of 25 to 30 meters with the river, forming canyons which irregular relief is a consequence of the soil type that is susceptible to water erosion, and produces the lost of large fractions of land. New urban settlements and the population concentration at consolidated areas with a high population density and an increment of the land imperviousness generates a higher direct runoff volume with consequences at the outlets to the water bodies receivers. The geomorphology of the place is analyzed, identifying the formation of gullies in urban areas and their backsliding effect which compromise the stability of structures. Actions of effects mitigation are evaluated taking as a reference studies and projects of storm and sewer drains of the following years: 1997, 1999, 2012 and 2015. |
