Can rainfall seasonality trigger soil water repellency in a tropical riparian forest?

Abstract Though riparian areas generally have a shallow water table and higher soil moisture compared to upslope areas, climatic seasonality may trigger repellency in tropical forests, which, if persistent, could negatively affect essential ecosystem functions related resources protection such as reduced overland-flow, sediment transport, nutrient filtration. The objective of this study was answer the following: can forests develop repellency? If so, does infiltration on seasonal basis? For this, were measured grid 72 points during dry wet month forest with region highly marked seasonality. Water significantly different between months. affected month, its effect insignificant. As result, capacity observed over period. Previous research has claimed that development persistence soils promote other hydrological processes overland flow. findings shown here demonstrate phenomenon not persist longer than season.
