Resumen

This study has been developed on a semi-arid catchment located in Mexico; the objective of this research is to measure rainfall interception, and to evaluate the effect of interception in Intensity, Duration, Frequency curves. The rainfall interception was determined from rainfall simulation at several intensity levels on grass vegetation coverage samples taken from experimental zone, where income precipitation, runoff, change in soil water storage and soil drainage were measured, with these, water balance for events of simulated rainfall on vegetation coverage were performed. From maximum rainfall in 24 hours intensity-duration-frequency relationships of rainfall for return period of 2, 5, 10 ,25, 50 and 100 years is obtained, evaluating the interception effect on those curves when establishing four sceneries of different coverage. From the rainfall simulations performed it was stated that the intercepted percentage on grass vegetation had an average of 2.33% of the totality of income. IDF curves were affected on approximately 2.89% on the scenery that consists of just grass vegetation coverage; on the scenery that consists of tree vegetation coverage, the effect was 11.15% and 19.85% on the scenery that consists of tree and grass vegetation coverage. Due to the above mentioned, the runoff in a basin decrease significantly.
