Resumen
Descripción
Runoff on susceptible terrains that is not associated with adequate drainage causes soil erosion, as gullies. 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.
