Abstract

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.
