Reactive Transport Of Solutes In The Hyporheic Zone
Abstract
The exchange processes at the surface-subsurface-interface (hyporheic zone) are of substantial relevance for river ecosystem functioning as they affect patterns of species distribution in relation to microbial transformations of organic matter and nutrients. The transport of chemical species through sediments are influenced in a complex fash- ion by a variety of factors, among others the morphology, the permeability of the river bed sediment, the variability of discharge and suspended load, groundwater gradients etc. In order to better understand the metabolism of the hyporheic zone a multidisci- plinary research project has been established on the River Lahn, a medium scaled river in Germany. The presentation will account on scale depending exchange processes and their effect on nutrient supply of the hyporheic zone.
