Abstract

Vegetation is widely accepted as an effective and environmentally friendly approach to mitigating slope failure. However, due to global warming, very high rainfall intensity might become more common. Rainwater infiltration in a sloping ground was studied, using a vegetated slope model subjected to very high rainfall intensity. The model slope was planted with the grass species Axonopus compressus to create two soil layers of uniform thickness, one with plant roots and one without. It was found that, for every simulated rainfall intensity used in this study, water infiltrated vertically in both soil layers. Furthermore, even under simulated rainfall of very high intensity, there existed a final infiltrated water content (

θ_{f}

) whose magnitude could be approximated from the k-function of the soil and the final infiltration capacity. Results from this study would enhance the knowledge of rainwater infiltration in a vegetated slope subjected to high rainfall intensity, and hence the stability assessment of vegetated slopes.

期刊介绍： Physics and Chemistry of the Earth is an international interdisciplinary journal for the rapid publication of collections of refereed communications in separate thematic issues, either stemming from scientific meetings, or, especially compiled for the occasion. There is no restriction on the length of articles published in the journal. Physics and Chemistry of the Earth incorporates the separate Parts A, B and C which existed until the end of 2001. Please note: the Editors are unable to consider submissions that are not invited or linked to a thematic issue. Please do not submit unsolicited papers. The journal covers the following subject areas: -Solid Earth and Geodesy: (geology, geochemistry, tectonophysics, seismology, volcanology, palaeomagnetism and rock magnetism, electromagnetism and potential fields, marine and environmental geosciences as well as geodesy). -Hydrology, Oceans and Atmosphere: (hydrology and water resources research, engineering and management, oceanography and oceanic chemistry, shelf, sea, lake and river sciences, meteorology and atmospheric sciences incl. chemistry as well as climatology and glaciology). -Solar-Terrestrial and Planetary Science: (solar, heliospheric and solar-planetary sciences, geology, geophysics and atmospheric sciences of planets, satellites and small bodies as well as cosmochemistry and exobiology).
