    This paper examines the partitioning of total P (TP) between dissolved (TDP) and particulate (PP) phases in the 2900 km2 catchment of the River Avon, Warwickshire, over the period December 1994 to June 1995. Flow, sediment concentration, TP, TDP and PP data are presented for a selection of sites. P erosion potential has been determined by measuring the concentration of P in the < 63 μm particle size fraction of 18 soil types. Results indicate that PP accounts for 52% of the weighted daily TP load at the catchment outlet. Higher PP concentrations occur in rivers with major sewage effluent inputs. The greatest P erosion potential is associated with surface-water gleyed soils. Many soils have as much as 80% of P in bioavailable form.
