Zusammenfassung |
In river basins, soils, groundwater, riparian zones and floodplains,
streams, rivers, lakes and reservoirs act as successive filters in which the
hydrology, ecology and biogeochemical processing are strongly coupled and
together act to retain a significant fraction of the nutrients transported.
This paper compares existing river ecology concepts with current approaches
to describe river biogeochemistry, and assesses the value of these concepts
and approaches for understanding the impacts of interacting global change
disturbances on river biogeochemistry. Through merging perspectives,
concepts, and modeling techniques, we propose integrated model approaches that
encompass both aquatic and terrestrial components in heterogeneous
landscapes. In this model framework, existing ecological and biogeochemical
concepts are extended with a balanced approach for assessing nutrient and
sediment delivery, on the one hand, and nutrient in-stream retention on the
other hand. |
