ABSTRACT
This article presents the comparison between the indirect determination of the
transported dissolved phosphorus (using the equation of Sharpley, 1995), based on usually used enrichment ratio and assumed share of the dissolved phosphorus in the total transported phosphorus during the erosion event, and the direct determination of the transported dissolved phosphorus amount, based on the newly derived methodology in the Býkovice catchment. The inputs into the calculation are the dissolved phosphorus concentration in runoff and the bioavailable phosphorus concentration in the soil (Melich III test) measured in the Býkovice catchment during the synthetic c rainfallrunoff events

Keywords: Water erosion, sediment transport, enrichment ratio, total phosphorus,
