✦ Synopsis

A conceptual model is presented to estimate the concentrations of pesticides appearing in surface waters following their application as part of agricultural production. The model has been formulated particularly to deal with soils that are prone to bypass Ñow and require artiÐcial sub-surface drainage. Pesticide concentrations and loads can be calculated at Ðeld drainage outlets or for whole headwater catchments. The data required to run the model are generally readily available from published sources (within the UK) and these data have been detailed. The assumptions made in the model are stated and the limitations with respect to the general applicability of the model are discussed.
