SCIMAP - Diffuse Pollution Risk Mapping
Steph Dixon has completed her MSc by Research that looked at how to incorporate temporal issues associated with rural diffuse pollution within the SCIMAP risk mapping framework. The full Masters by Research thesis is on the Durham University e Thesis site at http://etheses.dur.ac.uk/6895/

The hydrological and biogeochemical processes that operate in catchments influence the ecological quality of freshwater systems through delivery of fine sediment, solutes and organic matter. Most models that seek to characterise the delivery of diffuse pollutants from land to water are reductionist. The [...]

The concept of connectivity is increasingly being applied in hydrology as researchers attempt to move beyond the traditional partial or variable source area models for runoff generation and consequent material transport to recognize that the flux of water and the materials it [...]

Inverse modelling of diffuse pollution risks in agricultural catchments
Milledge, D, Lane, S N, Heathwaite, L and Reaney, S
Watershed scale processes can influence instream aquatic ecosystems, through delivery of fine sediment, solutes and organic matter. Certain areas in a watershed are critical sources, where the ability both to entrain [...]
