Predicting Sedimentgraphs Small Agricultural Catchment
2009/10/23
The key components of a sedimentgraph prediction procedure for small agricultural
catchments are outlined in the paper. An instantaneous unit sedimentgraph
(IUSG) based on the IUH and on a dimension...
Lacustrine wetland in an agricultural catchment：nitrogen removal and related biogeochemical processes
Lacustrine wetland agricultural catchment biogeochemical processes
2009/4/29
The role of specific catchment areas, such as the soil-river or lake interfaces, in removing or buffering the flux of N from terrestrial to aquatic ecosystems is globally recognized but the extreme va...
Water quality improvements from afforestation in an agricultural catchment in Denmark illustrated with the INCA model
afforestation arable land forest hydrology
2009/3/6
Intensive agricultural land use across Europe has altered nitrogen (N) budget of catchments substantially, causing widespread N pollution of freshwater. Although the N cycle in forests has changed du...

Nutrient leaching from agricultural production is still recognised as a major environmental problem in Finland.
Evidence for a delayed response of riverine phosphorus exports from increasing agricultural catchment pressures in the Lough Neagh catchment
riverine phosphorus exports riverine phosphorus exports
2014/4/30
Total phosphorus (TP) exports from the rivers draining into Lough Neagh increased between 1974 and 2000
despite lower TP inputs to the rivers from point sources. Over this period annual diffuse expor...
