Abstract
The use of dual drainage models have increased significantly in the past decades, mostly because of advances in mathematical and GIS tools methods. This type of modelling provides precise diagnosis and can be applied to evaluate storm water infrastructure and diverse drainage alternatives. This study aimed to analyse minor and major drainage relations in Dona Eugênia River Basin, located in the metropolitan area of Rio de Janeiro, Brazil. Two alternatives were simulated using MODCEL. The first one considered only the terrain surface layer, while in the second the layer containing a designed storm sewer was introduced. The results provided information on where minor drainage gaps were located and on the effects of the storm sewer network discharges in the major drainage system.
