Abstract

This study has been developed on a semiarid zone 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 covered vegetation 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 covered vegetation were performed. From maximum rainfall in 24 h intensity-duration-frequency relationships (IDF) of rainfall for return period of 2, 5, 10, 20 and 50 years is obtained, evaluating the interception effect on those curves when establishing four sceneries of different coverage.

Key words: Rainfall interception, intensity-duration-frequency curves, water balance, rainfall simulation, rural hydraulic structures.
