The hydrological behavior of the Retama sphaerocarpa has been studied in the east of Madrid. For it, experiments with rainfall simulator have been carried out with an intensity of 108 mmh1 on the study parcels. Based on the obtained results, we can say that the witnesses of the Retama favors the infiltration, either in association with the vegetation that grows under their canopy or without her, and that the absence of that herbaceous vegetation causes an increase of the runoff. On the other hand, the curves of variation of the runoff rate are adjusted to the equation developed by Mitscherlich, with a half r of 0,97, for a significance of p <0,001.
Key words: erosion, runoff, retama, hydrological behavior, infiltration, simulated rainfall.
