Sources of eutrophication: hydrological pathways of catchment nutrient export

  title={Sources of eutrophication: hydrological pathways of catchment nutrient export},
  author={Louise Heathwaite},
The relative importance of different hydrological pathways (surface runoff, subsurface flow, preferential flow) for nitrogen (N) and phosphorus (P) delivery in agricultural catchments is evaluated. The assessment takes account of the different nutrient loads from agricultural land and the role of land use distribution and zonation (e.g. buffer zones) in modifying diffuse nutrient loads before they reach the drainage network. The paper draws on a number of research studies on nutrient transport… CONTINUE READING
