Modeling diffuse pollution with a distributed approach
Water Science and Technology, 2002 The transferability of parameters for non-point source pollution models to other watersheds, especially those in remote areas without enough data for calibration, is a major problem in diffuse pollution modeling. A water quality component was developed for WATFLOOD (a flood forecast hydrological model) to deal with sediment and nutrient transport.

Evaluation of global change impacts on diffuse pollution [PDF]
F1000 Biology Reports, 2009 In a global change context, several recent advances in the field of hydrology and biogeochemistry suggest that a move from a riparian to a river drainage basin perspective is necessary to reframe research and thus provide a more integrated scientific understanding to inform water- and land-use management and policy.

Development and testing of a risk indexing framework to determine field-scale critical source areas of faecal bacteria on grassland. [PDF]
, 2009 This paper draws on lessons from a UK case study in the management of diffuse microbial pollution from grassland farm systems in the Taw catchment, south west England. We report on the development and preliminary testing of a field-scale faecal indicator
