The Four Interfaces' Components of Riparian Zones

Le résumé fourni par la source

Riparian zones are constituted of four interfaces with different biogeochemical drivers and effects on stream water quality and function. The interface between: upslope and wetland, wetland and stream surface water, stream surface water and groundwater, and stream surface water and the atmosphere. Wetlands classically present both soil anaerobic conditions and organic matter accumulation. Riparian subsurface flows are so heterogeneous that heavy hydrogeological monitoring is needed to predict the local residence time of nitrate, which limits the possibility to use this type of approach in environmental management plans. The transition between riparian groundwater, hyporheic zone, and surface stream water can be understood as a continuum of hydrological and biogeochemical conditions, precluding delineation of a physical boundary between these water bodies. Stream water temperature represents the balance of energetic fluxes across the surface water–groundwater and surface water–atmosphere interfaces.
