Interception by vegetation is one of the primary variables controlling hydrological and geo-environmental issues comparable to erosion, landslides and floods. Interception, together with precipitation and evapotranspiration, is required for the modeling of infiltration, percolation and runoff. Unfortunately, the measurement of interception within the area is time consuming, burdensome and topic to testing parameters with comparatively excessive variability. In this context, experiments utilizing rainfall simulators (RSs) have the potential to offer another method that addresses most of the restrictions of area experiments. This paper presents a new method to guage interception that mixes a RS and the monitoring of the wetting entrance utilizing pore-water stress instrumentation at particular places of the specimen. Two specimens are required, one with and one other with out vegetation. The proposed method was utilized to Paspalum notatum (bahiagrass) and a tropical soil. The outcomes indicated a mean interception of 5.1 mm of the simulated rainfall for a slope at 15 levels, rainfall depth of 86 mm h−1, and period of 60 min. Furthermore, the vegetation decreased the floor runoff that contributes to erosion. The proposed technique will allow research on the interception mechanisms and the varied concerned variables, with advantages to the modeling of soil-vegetation-atmosphere interplay.
