Resumo

Samborondón has a very high population growth rate; causing an increased urban development, pavement works and the reduction of the green areas, regarding the construction areas, producing a remarkable increase of the stormwater drainage, wich is conducted through hydraulics structures up to its final discharge in channels, estuaries or simply dumping it into the Babahoyo or Daule rivers. Babahoyo river geomorphology has provided information about islets due to the sediments buildup on its cause, because of the basin contribution, erosion and because of the tides entering the gulf. The present of this sediments inside the river cause, influences on the storm sewer system discharge levels; many times, causing its collapse and small floods, wich like the channels discharging directly into the river, have a backwater effect at the exact moment of discharge. This investigation, aims to zoning urban and riverside areas, which are more likely to be flooded, control and discipline urban occupation through a compatible densification according to the flood risks; in order to avoid urban areas hydrograph increment and to suggest possible theoretical solutions using hydraulic modeling samples.
