| description | Riparian buffer zones play an important role as nutrient pollution controls for rivers.
We provide a harmonized, explorative quantitative and spatially explicit continental
assessment of nitrogen and phosphorus potential retention in riparian buffer zones along
the European river network CCM2 (Catchment Characterization and Modellling). Diffuse
emissions of nutrients from fertilized cropland and pasture, based on a statistical model
(GREEN (Geospatial Regression Equation for European Nutrient Losses)), are partitioned
into surface and subsurface flow pathways based on the innovative SUGAR (Surface
water/Groundwatercontribution index) index. Surface flow N and P emissions are assumed to
undergo attenuation as a function of riparian buffer width. In contrast, the attenuation
of subsurface flow emissions and emissions from wetlands is assumed to be independent of
buffer width. Buffer attenuation follows a nutrient-specific negative exponential decay
function. For the study area, we estimate retention in surface runoff emissions of 33% for
nitrogen and 65% for phosphorus. The results represent a valuable data source for water
basin management with respect to water quality improvement, in particular buffer zone
restoration. |
