Gullies and drainage continue to be major issues in reclamation projetcs since soil erosion can be reactivated after the application of recovery measures. This paper describes a low-cost project framework for macrodrainage for a gully in Nazareno (MG, Brazil) to provide support to gully management and recovery. We used a simple methodology with the application of Geographic Information Systems (GIS) and cocentrated hydrologic and hydraulic models (freely available softwares). Tha basin has steep slopes (8 to 20%) and the water flows mainly to the northwest, wich contribute to exarcerbate erosion problems. We studied the effect to environmental conditions odf different simulations to elaborate a drainage system project using the free software tools. Therefore, the findings of this paper can aid gully management and recovery for this and other areas with similar issues.  aDrainage channels  aErosion control  aGeographic information systems  aGully erosion  aHydrologic models  aSimulation models  aSoil  aCanal de escoamento  aControle da erosão  aDrenagem  aHidráulica  aModelo de simulação  aRecuperação do solo  aSistema de informação geográfica  aSolo  aBarranco  aCanales de drenaje  aControl de la erosión  aErosión de cárcavas  aMétodo SCS  aMinas Gerais  aModelos de simulación  aModelos hidrológicos  aNazareno (MG)  aSCS method  aSistemas de información geográfica  aSoftware livre  aSuelo1 aRODRIGUES, V.
