Abstract: The purpose of this article is to predict the maximum discharge caused by runoff on hillslopes from very small rural basins. It is known that runoff generated by torrential rainfall in very small rural basins is difficult to predict but very important to know because of the damage it causes in isolated households or even villages. This work uses a methodology of determining the surface runoff hydrograph when the storm characteristics are known. The methodology was automated in a Geographic Information System model that can be used in any study if the user can provide the necessary parameters. The model, built by implementing some well known hydrologic methods in GIS, consists of four components that address the following requirements: the runoff depth in mm, the runoff coefficient, the travel/concentration time and the discharge. The discharge calculation is carried out by applying the rational method in each cell of the watershed to determine the specific dischar!
ge for that cell. If data from the meteorological predictions is used as an input, the model can be used as a tool included in a warning system as a method to anticipate flash flood.
